CHANGES IN CUPS V1.1.20

        - The signal handlers did not need to call sigset();
          this caused a recursion problem on some versions of
          IRIX (STR #422)
        - Moved the scheduler termination code into the mainline
          to be consistent with the way other signals are
          handled (STR #423)
        - The cupsaddsmb program didn't export the new CUPS
          driver for Windows properly (STR #390)
        - The ppdOpen() functions did not issue an error when a
          translation string exceeded the maximum allowed by the
          Adobe PPD specification (STR #399)
        - The default landscape orientation was not the same as
          that defined in the PPD file (STR #397)
        - Updated the pstoraster patch files and CUPS driver to
          work with Ghostscript 8 (STR #402)
        - The hpgltops filter did not skip PJL commands (STR
          #379)


CHANGES IN CUPS V1.1.20rc6

        - "lp -i jobid -H restart" would often return an error
          even though the job restarted successfully (STR #362)
        - The scheduler did not check for invalid allow/deny
          addresses such as "11.22.33.44/24". It now masks off
          the extra address bits and logs a warning message in
          the error_log file (STR #337)
        - The cupstestppd utility now checks for missing
          ImageableArea and PaperDimension attributes for each
          defined PageSize (STR #365)
        - The IPP code did not wait for a reply indefinitely on
          HTTP connections in "blocking" mode (STR #377)
        - The web interfaces did not rewrite the default printer
          URI properly (STR #369 and #299)
        - The LPD backend passed the C and L commands in the
          wrong order (STR #378)
        - The Dymo label printer driver did not set the label
          length properly (STR #373)
        - The scheduler did not support job IDs higher than
          99999 (STR #371)
        - The Visual C++ project files did not work (STR #366)
        - The scheduler's cupsLangSeek() function did not reset
          the "EOF" flag, preventing compressed files from being
          typed properly in some cases (STR #368)
        - The cupsLangGet() cache was only used if the locale
          name provided an explicit character set name (STR
          #354)
        - The CUPS API convenience functions did not call
          cupsLangFree() when they were done with the
          localization data (STR #354)
        - The scheduler did not return the
          job-hold-until-supported or job-hold-until-default
          attributes (STR #356)
        - The cupsaddsmb program did not support the new CUPS
          driver for Windows (STR #357)


CHANGES IN CUPS V1.1.20rc5

        - The scheduler did not initialize the browse socket
          file descriptor properly when only SLP browsing was
          enabled (STR #259)
        - The scheduler accessed the job attributes before they
          were set (STR #347, fix to STR #335)
        - The cupsCancelJob() function did not return 0 when the
          job could not be canceled (STR #340)


CHANGES IN CUPS V1.1.20rc4

        - The scheduler did not move the incoming job attributes
          in the operation group to the job group (STR #335)
        - The cupsDoFileRequest() function did not check for an
          early HTTP response while sending the file (STR #314)
        - The web interfaces did not quote #, ?, or . in printer
          names, which caused some problems with the generated
          URLs (STR #320)
        - CUPS couldn't be completely compiled with the -dDEBUG
          option (STR #331)


CHANGES IN CUPS V1.1.20rc3

        - More SLP changes (STR #259)
        - Revamped the child signal handling code to completely
          avoid deadlock issues on Solaris (STR #325)
        - The lpadmin command displayed an incorrect error
          message when the "-u" option was provided with no
          arguments (STR #313)
        - The web admin interface did not display an error
          message if the PPD file could not be loaded (STR #308)
        - The ppdEmit() functions did not use the correct
          orientation value position for custom page sizes (STR
          #292)


CHANGES IN CUPS V1.1.20rc2

        - The serial backend set the IXANY option on the port
          for XON/XOFF flow control; this caused problems with
          printers that returned status info but were not ready
          for more print data (STR #287)
        - The scheduler didn't support scripted index files
          (index.php, index.pl, etc. - STR #290)
        - The scheduler did not correctly localize script files
          with "GET" variables (STR #268)
        - Changes in job classification are now logged (STR
          #289)
        - Fixed a few more SLP-related bugs (STR #259)
        - Updated the user/group configure checks for MacOS X
          10.3 (STR #270)
        - Fixed an offset bug in the PDF filter (STR #284)
        - The cupsDoRequest() and cupsDoFileRequest() functions
          did not map several HTTP status codes to their IPP
          counterparts. This made detecting certain conditions
          very difficult (STR #277)
        - Config, spool, and status files are now owned by the
          scheduler user (usually root) with read permission for
          the filter group (STR #283)
        - The HP-GL/2 filter did not support the SI command,
          some values for the AD and SD commands, and did not
          rotate labels properly via the DI command (STR #282)
        - The fax support did not update/set the job-hold-until
          attribute when a fax job fails (STR #269)
        - The cupsLangGet() function didn't support locales of
          the form "ll.charset" (STR #271)
        - The scheduler did not use the charset when getting the
          language localization for a request; this caused extra
          disk IO for every request (STR #271)
        - The scheduler did not support requests with more than
          one language specified (STR #267)


CHANGES IN CUPS V1.1.20rc1

        - The scheduler now waits up to 60 seconds before
          restarting to allow active jobs to complete printing
          and pending requests to be processed (STR #226)
        - The web interface did not work on systems where time_t
          is 64 bits (STR #262)
        - Added backend tweeks and content-length check from Red
          Hat (STR #253)
        - The USB backend now uses the 8255 constants instead of
          the standard constants when reporting printer status
          bits on Linux (STR #254)
        - Added new cupsDoAuthentication(), cupsGetFd(),
          cupsGetFile(), cupsPutFd(), and cupsPutFile() functions
          to the CUPS API (STR #112)
        - The PDF filter always scaled and offset pages; this
          caused problems under MacOS X, so now the "fitplot"
          option controls whether PDF files are scaled to fit
          within the printable area of the page (STR #250)
        - The LPD backend did not support the port number in a
          URI (STR #247)
        - Some filters didn't properly support boolean options
          (STR #249)
        - Landscape PDF files were not always offset by the
          correct amount when rotating (STR #243)
        - The scheduler could hang in a call to localtime() when
          logging messages from the signal handler (STR #242)
        - The PDF filter no longer prints form widgets; this
          duplicates the behavior of Acrobat Reader (STR #241)
        - cupsGetPPD() didn't handle a late termination of a
          HTTP connection with the server (STR #220)
        - ppdOpen() did not correctly check for "*PPD-Adobe-4."
          on the first line of a PPD file. This caused incorrect
          PASS results for some PPD files (STR #233)
        - cupsEncodeOptions() did not allow boolean options to
          use "yes" and "on" for true values (STR #227)
        - The pstops filter only sent the TBCP exit sequence if
          it was defined in the JCLEnd attribute in the PPD file
          (STR #224)
        - Support for more than 1024 files was broken on Solaris
          9 (STR #217)
        - The setgroups() calls now pass in 1 group (the
          configured group) instead of 0 for compatibility with
          BSD and Darwin (STR #213)
        - The scheduler's built-in broadcast throttling was
          ineffective since incoming packets would cause the
          next group of outgoing packets to be sent immediately
          rather than waiting for the next time slot (STR #211)
        - Added a new ppdSetConformance() function to set the
          conformance requirements for PPD files. Currently only
          two levels are defined, PPD_CONFORM_RELAXED and
          PPD_CONFORM_STRICT, and the default is the relaxed
          level (STR #212)
        - The IPP backend did not correctly execute the
          pictwpstops filter on OSX (STR #210)
        - The LPD backend did not set the banner class when the
          "banner=yes" option was specified in the device URI
          (STR #209)
        - The imagetoraster filter did not support all of the
          page device attributes (STR #208)
        - The pdftops filter incorrectly auto-rotated pages when
          the user already had specified the proper orientation
          (STR #207)
        - Fixed AIX shared library support (STR #201)
        - Added support for live testing with Valgrind (STR
          #193)
        - The CGI programs now collect the list of needed
          attributes for the class, job, and printer template
          files (STR #192)
        - The scheduler now passes the first port that is bound
          to the local loopback or "any" addresses to the CGI
          programs rather than the port that the browser
          connected to (STR #103)
        - The cupstestppd program now checks for bad
          JobPatchFile attributes and incorrect versions of the
          Manufacturer attribute for HP printers (STR #155)
        - The filter makefile incorrectly installed
          libcupsimage.a in the filter directory (STR #180)
        - The scheduler did not verify that the job history
          files define the job-priority and
          job-originating-user-name attributes (STR #178)
        - The pstops filter didn't handle poorly-formed binary
          PostScript files that had CTRL-D's in them (STR #156)
        - The ppdOpen*() and cupsLangGet() functions did not
          make a copy of the old locale strings when using the
          POSIX locale when reading files, which apparently
          caused problems with some implementations of the
          standard C library. (STR #159)
        - The pdftops filter did not work properly with some
          embedded Type1C fonts (STR #177)
        - Updated the pdftops filter to be based upon Xpdf
          2.02pl1 (STR #191)
        - The scheduler did not reset the group list when
          running CGI and filter processes (STR #185)
        - The scheduler no longer calls malloc and free from the
          signal handlers (STR #190)
        - The USB backend now uses the manufacturer and model
          strings if the description string is not available
          (STR #174)
        - The ppdOpen functions still supported the
          VariablePaperSize attribute, which was removed in v4.0
          of the PPD spec.  This caused problems with PPD files
          that relocated the PageSize option to a non-standard
          group (STR #158)
        - The cups.list file referenced MAN1EXT, MAN3EXT, and
          MAN5EXT, but none of those were actually defined (STR
          #147)
        - Chunked requests could cause a Denial of Service if
          the connection is terminated before the first byte of
          chunk data is sent/received (STR #143)
        - Printers with special characters in their names were
          not accessible from the web interface (STR #120)
        - The lpstat command now shows the correct interface
          script or PPD file, if any, for a print queue (STR #89)
        - The lpstat command now shows the printer-state-message
          and printer-state-reasons attributes whenever they are
          not blank (STR #152)
        - The French and German option-conflict.tmpl template
          files did not get installed (STR #148)
        - The cups.list.in file did not work when compiling
          without shared libraries (STR #149)
        - The DSOFLAGS included the LDFLAGS, which causes
          problems on at least HP-UX (STR #150)
        - The fax printer support did not keep track of the fax
          capability bit (STR #144)
        - The appleLangDefault() function could leak a small
          amount of memory (STR #145)
        - The ppdOpen() functions now mirror all normal
          attributes to the attribute list; previously only
          certain unassigned attributes would be added (STR
          #139)
        - The ppdEmitJCL() function wrote JCL commands to stdout
          instead of the passed file pointer (STR #142)
        - The httpGets() function could, in certain states,
          block waiting for data (STR #132)
        - The cupsEmitJCL() function not outputs an empty @PJL
          command after the PJL language escape to work around
          bugs in certain PJL implementations (STR #131)
        - The cupsEmit*() functions didn't set the orientation
          value properly (STR #127)
        - The cups.spec file didn't list the rc2.d init
          directory or the cupstestppd file (STR #134)


CHANGES IN CUPS V1.1.19

        - The GNU TLS code incorrectly used
          gnutls_check_pending() instead of
          gnutls_record_check_pending() (STR #128)
        - The ppdEmit() functions output "PageSize Custom"
          instead of "CustomPageSize True" in the DSC comments.
          Also, the custom page size code did not use the
          ParamCustomPageSize attributes (STR #127)
        - The cupstestppd command did not list the conflicting
          options (STR #123)
        - The lpq command did not ensure that there was
          whitespace between the fields in the job listing (STR
          #117)
        - The German web templates had errors (STR #119)
        - The configure script didn't specify the static
          libraries properly when configuring with the
          --disable-shared option (STR #104)
        - The cups.list file used file dependencies for package
          formats other than portable, RPM, and Debian (STR #98)
        - cupsLangGet() didn't use its language cache (STR #97)
        - "lpq -P" would segfault instead of showing a usage
          message (STR #94)
        - Fixed compiler warnings in pdftops filter (STR #96)


CHANGES IN CUPS V1.1.19rc5

        - Jobs with banner pages that were printed to implicit
          classes would get double banner pages for each
          file/banner in the job (STR #68)
        - The mime.convs file was missing the filter definition
          for Windows BMP (image/x-bitmap) files (STR #85)
        - The scheduler allowed some READ-ONLY job attributes to
          be set, which could cause the scheduler to fail on the
          next restart (STR #82)
        - The lp and lpr commands did not report when the
          scheduler was not responding; instead, the user would
          incorrectly see a "no default destination" error (STR
          #70)
        - cupsLangGet() could fail on OSX due to a corrupt
          language preference (STR #78)
        - Added more checks for HTTP request timeouts.
        - The scheduler dropped the first non-alpha character
          after an open brace when doing attribute substitutions
          in banner pages (STR #77)
        - The scheduler child might send SIGUSR1 to the parent
          before the signal handler was installed; this didn't
          prevent the scheduler from starting but produced an
          annoying error message (STR #45)


CHANGES IN CUPS V1.1.19rc4

        - The lp command did not accept "-" for printing from
          the standard input as required by POSIX 1003.1 (STR
          #59)
        - Added the job-originating-host-name information for
          the page_log file documentation in the SAM (STR #31)
        - The German web interface templates did not use the
          right paths for job operations (STR #54)
        - The scheduler would consume all available CPU if
          started with a pending job in the queue (STR #35)
        - The polling daemon allocated an extra localization
          buffer but did not free it, causing cups-polld to
          eventually use all available memory (STR #40)


CHANGES IN CUPS V1.1.19rc3

        - The scheduler could get in an infinite loop cancelling
          jobs using "cancel -u user dest" (STR #48)
        - The "cancel -u user" command did nothing (it should
          cancel all jobs on all printers owned by the named
          user - STR #48)
        - The scheduler would write 0-length job control files
          (STR #46)
        - Updated the French man pages (translation provided by
          Gilles QUERRET)
        - The scheduler would delete all printers from
          printers.conf if a job was active when a HUP signal
          was handled (STR #47)
        - The cups-polld program would leak memory if it was
          unable to send browse packets to the loopback
          interface (STR #40)
        - The scheduler did not put the
          job-originating-host-name attribute in the job
          attributes group.
        - The text filter did not default to wrapping text as
          defined by the IPP implementation document.
        - Scan backends first, PPDs second (STR #37)
        - Updated the Netatalk documentation in the SAM (STR #38
          and #39)
        - The test suite sent text files to a non-PS print queue,
          which requires ESP Ghostscript (provided separately).
          Now send the JPEG test file (STR #33)
        - The test suite did not show the estimated disk space
          requirements (STR #33)
        - The test suite did not set the MaxLogSize directive to
          0 to prevent log file rotation (STR #33)
        - The test suite still setup the old CUPS Ghostscript
          symlinks (STR #33)
        - The pstops filter did not report the correct number of
          copies for the page_log file when printing collated
          copies to a printer that doesn't support them in
          hardware (STR #32)
        - cupsLangGet() needs to set the CTYPE locale to "C"
          (POSIX) to avoid erroneous tolower/toupper values (fix
          suggested by Bjoern Jacke)
        - Fixed a typo in the cups.list.in file.
        - Updated all of the Western European locales to default
          to ISO-8859-15 (for Euro support, suggested by Bjoern
          Jacke)
        - Updated the German message catalog (update provided by
          Bjoern Jacke)


CHANGES IN CUPS V1.1.19rc2

        - cupsLangGet() now sets the encoding field based on the
          trailing charset in the locale name, and doesn't look
          for a message catalog in a specific locale.charset
          directory.  This fixes STR #26 and is more in line
          with the CUPS 1.2 implementation.
        - The configure script now aborts if the "ar" command or
          compilers cannot be found.
        - The static cupsimage library was not built by default.
        - The path for the "ln" command was hardcoded in
          Makedefs.in instead of being checked at configure time
          (STR #28).
        - Banner pages containing unescaped { characters would
          not work.
        - The printer-state-time collection attribute was
          encoded as an enumeration instead of an integer.
        - The printer-is-accepting-jobs collection attribute was
          was not added to the collection value.
        - The printer-state-sequence-number collection attribute
          was not added to the collection value.
        - Fixed typo and const mismatch in IPP backend.
        - Updated the man pages for the new configuration
          directives.
        - Updated the SAM for MacOS 10.2, the CUPS drivers for
          windows, the available LPD backend options, and the
          new configuration directives.
        - The imagetops filter didn't position images properly
          on the page (STR #18)
        - The configure script didn't add CPPFLAGS to the
          compiler options or LDFLAGS to the DSO options (STR
          #13)
        - The scheduler would try to write a debug log message
          when starting a job that contained a NULL string. 
          Since not all versions of snprintf() support NULL
          string pointers this caused some problems (STR #20)
        - The testipp program now supports reading of IPP
          message files such as those used for the job history
          in /var/spool/cups.


CHANGES IN CUPS V1.1.19rc1

        - Added CUPS support files for Java, Perl, and PHP
          (located in the "scripting" subdirectory...)
        - The scheduler now supports fast-reloads of the
          cupsd.conf file when it is updated via HTTP.
        - The scheduler always changed the ownership of log
          files; it now only does so if they are not in the /dev
          directory (i.e. don't want to change the ownership and
          permissions of /dev/null...)
        - Added libpaper support (patch from Jeff Licquia)
        - Added a new istring() rule for MIME types files that
          does a case-insensitive comparison of strings.
        - The cups-lpd mini-daemon now sends jobs to the default
          queue when an empty queue name (or "lp" and there is
          no "lp" queue) is sent.
        - The scheduler now supports fax queues identified by a
          "*cupsFax: True" attribute in the PPD file. When a job
          can't be sent, it is held for 5 minutes by default
          while other jobs are attempted.  The FaxRetryLimit and
          FaxRetryInterval directives control the number of
          retries and the time between retries.
        - The scheduler now preserves the default options of PPD
          files when modifying/upgrading an existing PPD file.
          When installing a new printer, the scheduler sets the
          default media size to Letter or A4 as appropriate for
          your locale.
        - The scheduler no longer limits the number of
          BrowseAddress, BrowsePoll, BrowseRelay, Listen, Port,
          SSLListen, and SSLPort directives to 10.
        - The scheduler now supports print files that have been
          compressed using gzip.
        - The scheduler used the stdio functions to read any job
          ticket information in a PostScript print job. Since
          some platforms limit the number of stdio files to 256,
          job ticket information was ignored when the server had
          a large number of clients connected to the system.
        - Filters and backends may now report the total number
          of pages ("PAGE: total NNN") to the scheduler.
        - The LPD backend now supports timeout and
          sanitize_title options (default to 300 and yes,
          respectively) and has some additional changes to
          reduce the chances of multiple copies being printed
          when only one copy was requested.
        - Fixed a polygon drawing bug in the HP-GL/2 filter.
        - Added a robots.txt file to the standard install to
          prevent search engines from indexing the CUPS server.
        - Added support for STATE: messages
          (printer-state-reasons), printer-state-history, and
          printer-state-time to the scheduler.
        - When using RunAsUser, the scheduler would initially
          start any previously queued (pending) jobs with
          RunAsUser disabled - all backends would be running as
          root.
        - If a backend failed for a printer, CUPS would
          incorrectly requeue the job for printing again.
        - Added support for IPP collections and files.
        - Added experimental support for generic CGI scripts and
          programs, Java, Perl, PHP, and Python to the
          scheduler. See the file "CGI.txt" for more
          information.
        - The CUPS API now supports HTTP cookies and the Expect:
          field.
        - The cancel command now correctly supports the "-u
          user" option to cancel all jobs for the named user.
        - The Purge-Jobs operation now supports the my-jobs
          boolean attribute and a new purge-jobs boolean
          attribute to control whether job history data is
          purged from the scheduler; the default is false for
          my-jobs and true for purge-jobs to match the original
          implementation.
        - The scheduler would not timeout printers when only
          using SLP browsing.
        - If the scheduler was unable to execute a filter, it
          would try to restart the job indefinitely until the
          filter could be executed.
        - When writing BSD printcap files, the scheduler now
          includes the rm and rp attributes, allowing the file
          to be exported to LPD clients. [Patch from Dominic
          Kubla]
        - The scheduler optimization to reference IPP attribute
          data instead of performing a full copy caused problems
          when the referenced data was deleted before it was
          sent.  It now only references attributes that change
          only when the scheduler is restarted.  The change also
          reduced the memory footprint of a printer object to
          2k.
        - The scheduler now holds signals while logging messages
          to avoid potential deadlock issues when handling
          signals on Solaris 8.
        - The lpadmin command now allows printer access control
          by group name as well as user name.
        - "lpoptions -l" got in an infinite loop if no default
          printer was available.
        - The scheduler now logs the job-originating-host-name
          attribute in the page_log file, and uses "-" for any
          empty fields (patch from Dominik Kubla).
        - The pdftops filter now scales PDF pages within the
          printable area of the page.
        - The pstops filter didn't include the page-label and
          classification boxes when printing EPS or non-
          conformant PS files.
        - The imagetops filter didn't always correctly position
          the image on the page when printing in landscape
          orientation.
        - The ppdEmit() functions now support the
          RequiresPageRegion attribute when sending InputSlot
          and ManualFeed commands.
        - The PPD loading code now supports standard options
          outside of OpenUI/CloseUI as required by the PPD spec.
        - The cupstestppd program has been upgraded to provide a
          concise PASS/FAIL report, additional detailed
          conformance testing, and support for gzip'd PPD files.
        - The PPD loading code is now much more strict when
          loading a PPD file, and tracks more format errors.
        - The scheduler ignored child signals when gathering the
          list of available devices, when it should have been
          using the default signal handler.
        - The cupsEncodeOptions() function could encode an
          option with a NULL last string.
        - The socket backend could report the wrong number of
          backchannel bytes if an error occurred on the link.
        - The cups-polld program now only sleeps after getting
          all printers and classes.  This allows for longer
          intervals without excessive delays before classes show
          up...
        - Added a new httpWait() function to support waiting for
          data for a specific number of milliseconds.
        - httpGets() now times out after 1 second on
          non-blocking HTTP connections.
        - The scheduler no longer accepts rangeOfInteger values
          that are out of order (e.g. 5-1)
        - The sides attribute was incorrectly sent as a name
          value; it is a keyword value.
        - The IPP backend now detects if the destination queue
          has gone away and reports an error.
        - The scheduler and HTTP API now allocate their select()
          sets to support larger numbers of clients on systems
          that support it.
        - The scheduler now sets the CFProcessPath environment
          variable under MacOS X.
        - The cupsLangDefault() function now uses the
          CoreFoundation localization API under MacOS X.
        - The httpSeparate() function didn't handle file URIs of
          the form "file:///path" properly.
        - The lpadmin command now supports a "protocol" option
          for specifying the binary communications protocol to
          use when printing binary PostScript data.
        - The scheduler did not properly parse the SystemGroup
          directive, so only the first group would be used.
        - Revamped how strings are stored in the scheduler,
          providing a substantial improvement in memory usage
          for systems with large numbers of printers.
        - The PostScript filter now supports binary PostScript
          files and files beginning with the PJL language escape
          sequence.
        - The PPD API now provides additional information from
          the PPD file.
        - The USB backend didn't compile on Solaris Intel.
        - The cupstestppd utility now supports the "-q" option
          (quiet) for use in scripts, etc.
        - Merged several weight-reducing changes into the CUPS
          baseline donated by Apple.
        - Added preliminary support for CDSA; patch provided by
          Apple.
        - Implicit classes are now created from identical
          printer classes on the network.
        - The lp command now supports a "-H restart" option to
          restart previously printed jobs.  This functionality
          only works if you have enabled the PreserveJobFiles
          option.
        - The scheduler now supports URIs in HTTP request lines
          to conform to the HTTP/1.1 specification.
        - The time-at-xyz attributes were not recognized in
          banner files if prefixed by a question mark, e.g.
          "{?time-at-creation}".
        - Added support for pre-filtering application/pictwps
          files on MacOS clients before sending them to a server
          via IPP.
        - The scheduler now allows file:/dev/null device URIs
          even if FileDevices is set to No.
        - CUPS uses strerror() for hostname resolution errors,
          when it should have used hstrerror().
        - The USB backend no longer tries to guess the serial
          number of a device from the USB devices file; this
          means that printers that don't report their serial
          numbers in the device ID string will not be
          individually selectable.
        - The pstops filter didn't handle page ranges properly
          when a page contained an embedded document.
        - Added a translation of the web interface to German.
        - When printing using the OutputOrder=Reverse option
          with duplexing, the output order is now truly
          reversed; the order of sub-pages when printing N-up is
          the same.
        - The pstops filter did not always output the extra
          blank page when printing a document with an odd number
          of pages with duplexing enabled.
        - The ippAddXYZ functions no longer allow the
          application to add less than 1 value.
        - Fixed a URL rewrite bug in the web interface - local
          access was sometimes redirected away from localhost...
        - The ppdOpen() functions could get in an infinite loop
          if the PPD file contained a keyword or text that was
          too large for the buffer.
        - Added preliminary support for GNU TLS; patch provided
          by Jeff Licquia.
        - Now timeout IPP attribute reads after 1 second inside
          an attribute definition.
        - Now timeout connections that have been shutdown (due
          to errors) after 30 seconds instead of the Timeout
          setting (300 seconds by default).  This provides
          faster recovery from DoS attacks.
        - A denial-of-service attack warning message was being
          written to the log files by the scheduler for every
          detection.  This caused a DoS of its own in some
          situations. The warning message is now written no more
          than once per minute.
        - Fixed the CIE colorspace support code in the image and
          PS RIPs.
        - The job-quota-period, job-page-limit, and job-k-limit
          attributes were not flagged as integers, so setting
          quotas would not work.
        - Added an additional response check in the scheduler to
          more quickly recover from denial-of-service attacks.
        - The cupstestppd file was incorrectly installed in the
          /usr/sbin directory instead of /usr/bin.
        - The EPM list file did not include the cupstestppd
          program or man page files.


CHANGES IN CUPS V1.1.18

        - Fixed a bug in the Set-Job-Attributes code in the
          scheduler that would cause it to crash or continuously
          write a job control file.
        - SECURITY FIX: The scheduler now provides a FileDevice
          directive to control whether new printers can be added
          using device URIs of the form "file:/filename".  The
          default is to not allow printers with these device
          URIs.
        - The scheduler did not compute the cost of filters
          properly, nor did it choose a multi-filter solution
          with a lower cost than a single filter solution.
        - Now install CUPS PPD file test utility (cupstestppd)
          to support basic conformance testing of PPD files.
        - The scheduler now logs an error message when it sees a
          non-conforming PPD file.
        - Upgraded pdftops filter to Xpdf 2.01 with fixes for
          TrueType fonts.
        - Added a MaxClientsPerHost configuration directive to
          provide limited protection against Denial of Service
          attacks.
        - SECURITY FIX: Potential underflow/overflow bug in web
          interface.
        - SECURITY FIX: Race condition in certificate creation.
        - SECURITY FIX: Bad URIs in browse packets could be used
          to exploint the web interface underflow/overflow bug.
        - SECURITY FIX: Some types of Denial of Service attacks
          were not handled properly, so once the attack was over
          the scheduler did not close the connections
          immediately on all platforms.
        - SECURITY FIXES: Added integer overflow/underflow
          checks for all image formats.
        - The pstops filter didn't reset the showpage operator
          back to its original at the end of a job; this
          prevented the concatenation of documents (used
          primarily for CUPS 1.2...)
        - The cupsGetPPD() function didn't always set the
          cupsLastError() value when an error occurred.
        - The IPP media, output-bin, and sides attributes took
          precedence over the corresponding PPD options, which
          caused inconsistent behavior under MacOS X with some
          PPD files.
        - The cupsaddsmb utility specified the wrong number of
          arguments to the adddriver command when adding the
          Win9x PostScript drivers.
        - The web interface did not always report the correct
          error message.
        - The scheduler did not clear the POSIX signal action
          structure when waiting for the child to send it a
          SIGUSR1 signal; this could cause the signal handler
          not to be called properly, preventing the parent
          process from returning.


CHANGES IN CUPS V1.1.17

        - The "manual_copies" option did not work when the LPD
          backend had to retry a print job.
        - The image filters did not convert GIF images properly.
        - The RunAsUser option was incompatible with the new
          daemon-mode code in 1.1.16.
        - Fixed a problem with the Set-Job-Attributes and
          PostScript job ticket code in the scheduler - the
          "last" attribute pointer was never updated, which
          could cause the scheduler to crash when applying job
          ticket data.
        - Fixed a problem in the scheduler that caused it to
          continue processing HTTP requests on a connection
          after it was shutdown.
        - The scheduler now allows accounts authenticated via
          PAM to not have a corresponding UNIX account, but
          group membership still requires the account name to be
          listed in the UNIX group file(s)...
        - The scheduler used a fixed-size (16k) buffer for
          encoding job options for filters; it now dynamically
          allocates and expands the buffer as needed depending
          on the options that are sent in a job.
        - The pdftops filter didn't support all of the MacOS
          characters for MacRoman encoded fonts.
        - The cupsEncodeOptions() and cupsParseOptions()
          functions now conform to the grammer defined by the
          current draft of the PAPI specification.  The main
          difference is that option=yes and option=no are no
          longer treated as boolean options.
        - The IPP backend didn't honor the encryption settings
          in /etc/cups/client.conf.
        - Fixed a potential bug in the HTTP code which was
          caused by servers sending the status line and
          newline(s) in separate packets.
        - User-defined classification strings are now printed
          verbatim - previously the classification box would be
          empty.
        - Re-added Spanish to the list of PPD languages that
          CUPS supports.
        - CUPS API library user and temp file updates for
          Windows.
        - The image filters did not properly handle grayscale
          printing of Sun Raster images.
        - The scheduler never reset the NumJobs variable before
          loading the job list (previously this only happened on
          a full start, so the problem was never apparent...)
        - The HTTP and IPP read/write code didn't handle EINTR
          (interrupted system call) errors.
        - When under high load, the scheduler could abort due to
          the wrong errno value after a select() call.  This was
          caused by the child signal handler.
        - Added new load tests to the test target to verify that
          cupsd can handle hundreds of simultaneous jobs without
          error.
        - The Solaris USB backend now supports the new device
          URI syntax.
        - The ppdOpen*() functions now reset the numeric locale
          settings while loading a PPD file.
        - Fixed the libtool build rules.
        - The manpage make rules didn't use $(MAKE) and
          $(MFLAGS) for the language subdirectories.
        - Now set the LC_TIME locale category to get the
          properly localized time string.
        - Fixed a problem in the scheduler that would cause the
          web interface problems when adding, modifying, or
          configuring a printer or class.
        - The backends now ignore SIGPIPE so that failed job
          filters will not stop a print queue.
        - The lpstat command did not allow for destination lists
          ("lpstat -v printer1,printer2")
        - Fixed parsing of long filter status messages in the
          scheduler.
        - Added some startup performance enhancements to the
          scheduler so that the printer object information is
          regenerated fewer times and the MIME type database is
          not filled with lots of empty filters for raw/direct
          queues.
        - The LPD backend now sends the job title as the print
          filename.
        - Added support for variable sizes in the EPSON dot
          matrix printer drivers.  This allows for pages as
          short as 1/2" (1 row of labels) and does not do an
          automatic form feed.
        - French translation updates.
        - The filters did not quote the page label string when
          embedding it in PostScript output.
        - The serial backend now enumerates serial ports under
          MacOS X.
        - The pdftops filter contained font rasterizer code that
          wasn't being used and that depended on X11.  This code
          has been removed.


CHANGES IN CUPS V1.1.16

        - The cancel and lprm commands now both display an error
          message and return a non-zero exit status if an
          attempt is made to cancel a job on a non-existent
          printer.
        - The lpoptions command incorrectly complained if a
          request to delete a non-existent printer was made.
        - If the client.conf file defines an alternate server
          name, the "configure printer" action in the web
          interface might not work.
        - The lpstat command now supports a "-W" option so that
          you can display completed jobs as well as
          not-completed (pending) jobs.
        - The lp and lpr commands did not return an error when
          one or more files in a set of files for printing could
          not be printed.
        - The lp, lpadmin, and lpstat commands now consistently
          return with a non-zero exit status when an error
          occurs.
        - The scheduler would not accept print jobs sent to a
          stopped remote printer.
        - The texttops filter incorrectly converted the page
          numbers in the prettyprint header to double-byte
          characters when printing a non-Unicode text file. This
          caused an extra space to appear between each digit in
          the page number.
        - The scheduler did not use a case-insensitive
          comparison when adding filters for a printer.
        - Upgraded the pdftops filter to Xpdf 1.01.
        - The scheduler no longer passes the page-border and
          number-up-layout attributes to filters when printing
          banner pages.
        - The LPD backend now uses a 30-second timeout when
          sending commands and control files, and a 30-second
          timeout when retrieving responses from an LPD server. 
          If a timeout occurs, it retries indefinitely.  This
          helps to make LPD printing over VPNs work more
          reliably.
        - The USB backend now supports device URIs based on the
          printer serial number and/or model number under Linux.
          This avoids the "wrong device filename" problem when
          using more than one USB printer.
        - Now just shutdown the receiving end of a client
          connection when sending an error that requires the
          server to disconnect from the client afterwards.  This
          fixes a problem when doing remote administration with
          encryption enabled.
        - The scheduler did not send a printer-state-message
          attribute if the string was empty; it now always sends
          this attribute.  This caused the printer message to be
          displayed for other printers in the web interface.
        - The LPD backend now supports a "manual_copies" option,
          e.g.: "lpd://server/queue?manual_copies=no", in order
          to handle copies for raw jobs to printers that don't
          implement the LPD protocol properly...
        - The "mirror" option was not being handled by the
          PostScript or image filters.
        - Updated the cupsaddsmb command to support the new CUPS
          driver for Windows NT/2k/XP.
        - Filter status lines longer than 1023 characters could
          cause the scheduler to get into an infinite loop.
        - The scheduler didn't reset the job state to pending
          when modifying an active printer.
        - Now limit the maximum number of recursion steps when
          searching for a filter for a job, in case a user
          defines a circular filter rule.
        - The PostScript filter would embed an invalid
          requirements comment in some cases.
        - Added support for embedded job tickets in PostScript
          files.
        - The PostScript filter now detects EPS files and should
          better handle printing EPS files.
        - The cancel command now ignores a trailing destination
          name when cancelling a specific job ID (Solaris
          compatibility).
        - The scheduler now rejects jobs with copies outside the
          range of 1 to MaxCopies, inclusive.
        - Added new MaxCopies directive to set the maximum
          number of copies that a user can request.
        - The scheduler didn't block signals while it processed
          others and when it forked processes.
        - The scheduler checked for new jobs to print when
          stopping a job.  This caused jobs to restart before a
          shutdown.
        - Updated the CUPS startup script to better support
          different timezones and to support the RedHat/Mandrake
          init script functions, if available.
        - The scheduler did not properly handle backslashes in
          banner files; it incorrectly assumed that "\c" should
          always be replaced by "c", instead of only looking for
          "\{" and replacing it by "{".
        - The texttops filter didn't handle prettyprint=no.
        - The text and HP-GL/2 filters didn't check for other
          common duplex option names like cupsMarkOptions() did.
        - "lpoptions -x printer" no longer clears the "default
          printer" status of the printer.
        - cupsTempFd() now stops trying to create a temporary
          file after 1000 tries, and aborts on any error other
          than EEXIST.  This should prevent lp/lpr hangs due to
          a bad or missing temporary directory.
        - The lpadmin command did not send the right URI to the
          scheduler when setting options on classes.  This
          caused a client-error-bad-request error.
        - The CUPS API convenience functions would attempt to
          connect to the remote server name in a
          "printer@server" printer name instead of dealing with
          the default (usually local) server.  Aside from
          causing user confusion, the remote server name might
          not be resolved properly, causing further problems.
        - "lp -q" would cause the "lp" command to segfault, as
          the program would try to print the option letter that
          caused the error using the wrong index into the
          command-line; bugfix from Debian.
        - Fixed a minor inconsistancy in the encoding of boolean
          attributes from printer options in
          cupsEncodeOptions().
        - Added a FilterNice directive which sets the priority
          of job filter processes that are run by the scheduler.
        - Added Solaris x86 USB printer support.
        - The USB backend now reports both the ulpt and unlpt
          devices under *BSD.
        - The "lpstat -o" command would truncate the
          "printer-jobid" string if it was longer than 21
          characters.
        - The PJL-based MIME type rules now look in the first
          1024 bytes instead of just the first 512 bytes to find
          the language mode.
        - The image file types are now listed explicitly in the
          mime.convs file so that additional image file formats
          do not use the standard CUPS image filters by default.
        - Updated the Software Programmers Manual to include
          all of the CUPS API functions.
        - ppdOpen*() no longer sorts choices for an option.
        - The web interface now enforces constraints in PPD
          files when configuring a printer.
        - When stopping a printer, the scheduler didn't set the
          printer state before stopping the current job.
        - The cupsaddsmb utility now lists all data files for
          Win9x and WinMe clients when installing that Windows
          driver.
        - Jobs submitted to a class now bounce immediately to
          the next available printer rather than waiting until
          that printer is available.
        - Filters and backends now also get the CLASS
          environment variable set when a job is printed to a
          printer class instead of a normal printer.
        - Added French translations of the web interface, CUPS
          Overview, Software Administrators Manual, and Software
          Users Manual contributed by Marian REYT-LLABRES.
        - Added several "hint" messages for common configuration
          problems that are stored in the error_log file.
        - httpSeparate() now unquotes %xx characters in the
          username:password field of a URI.
        - When starting the scheduler in daemon mode, the parent
          process now waits for the child to signal it is ready
          to accept connections.
        - Added -F option to cupsd to run cupsd in the
          foreground but detach from the controlling terminal
          and current directory.
        - The scheduler did not reload jobs when receiving a HUP
          signal; this would cause problems since the pointers
          into the file type database would no longer be valid
          for existing jobs.
        - The scheduler did not save the network interface list
          update time, thus no caching of the network data was
          actually provided.
        - Updated the SuSE PAM configuration file.
        - The LPD backend now supports a "reserve" option and no
          longer reserves a priviledged port by default.
        - The cupsaddsmb command now continues past printers
          that do not have a PPD file to export.
        - The lpstat command didn't treat printer names as
          case-insensitive.
        - The lpstat command now reports the printer location
          attribute with "lpstat -l -p".
        - Fixed a bug in the vsnprintf() emulation function,
          which was used on old versions of HP-UX, IRIX, and
          Solaris.
        - The number-up option was incorrectly being used when
          printing banner pages.
        - Added support for Greek and Slovak PPD files.
        - CUPS now supports printer names containing any
          printable character, e.g. "123-abc", "foo-bar", etc.
        - The null filter was not supported in mime.convs due to
          a bug in the filter validation code.
        - Changes in the default printer and printer attributes
          were not always reflected in the generated printcap
          file.
        - Implicit classes did not inherit the location or
          description from member printers.
        - The httpGetHostByName() function did not handle
          hostnames that started with a number.
        - Updated the filters to use the %cupsRotation comment
          instead of %%Orientation to auto-rotate pages, since
          the use of %%Orientation is inconsistent.
        - Added the RootCertDuration directive to control how
          often the root authentication certificate is updated.
        - Increased the size of the IPP write buffer to 32k to
          allow for larger attribute values and to provide more
          efficient output of large numbers of attributes.
        - The polling daemon now retries the initial connection
          to the remote server; this fixes a problem when the
          remote server is unavailable when the scheduler starts
          up...
        - The scheduler didn't validate Digest users against the
          system group(s), so Digest and BasicDigest
          authentication didn't work for administration
          operations.
        - The scheduler now passes the SHLIB_PATH environment
          variable to child processes (HP-UX shared libraries)
        - The scheduler now maps accesses from the loopback
          interface to "localhost".
        - The cups-lpd mini-daemon sent a status code byte in
          response to queue state commands, but those commands
          only return textual data.


CHANGES IN CUPS V1.1.15-1

        - The lpc and lprm sources didn't include the CUPS
          string function header, which is required on systems
          that don't have their own snprintf() function.
        - The French manpage Makefile tried to install the
          language subdirectories when it (obviously) didn't
          have to.


CHANGES IN CUPS V1.1.15

        - Updated the CUPS license agreement for the new MacOS
          and OpenSSL license exceptions.
        - The printer-info attribute now defaults to the printer
          name if no value has been set.
        - ppdOpen() and friends now add an "Auto" InputSlot
          option if none is provided to automatically select the
          correct tray.
        - Updated the ppdEmit() and ppdEmitFd() functions to
          (re)mark the correct PageSize or PageRegion option
          depending on the selected ManualFeed or InputSlot
          options.
        - ppdEmitFd() didn't handle custom page sizes.
        - Darwin uses <pam/pam_appl.h> instead of
          <security/pam_appl.h>.
        - The jobs.cgi web interface now handles all job
          operations, allowing the administrator to allow "job
          administrators" or operators to manage jobs (but not
          queues) on the server.
        - The cupsDoFileRequest() function now checks if the
          filename passed into the function is a directory, and
          returns the IPP_NOT_POSSIBLE error if so.
        - New SCSI printer backend.
        - Cleaned up handling of locales with trailing character
          set definitions.
        - Fixed handling of invalid PPD attributes inside
          OpenUI/CloseUI.
        - Fixed a problem with SSL and the job, printer, and
          admin CGIs on ports other than 443.
        - The scheduler didn't handle AuthClass properly.
        - Added French translation of man pages.
        - Updated the text filter to support the const_cast,
          dynamic_cast, and static_cast keywords in ISO C++.
        - Now use strlcat() and strlcpy() (or emulation
          functions) for easier string/buffer protection.
        - The auto-generated printcap/printers.conf files now
          have a small comment header explaining where the file
          comes from...
        - The PostScript filter now supports 6, 9, and 16-up
          output, as well as new page-border and
          number-up-layout options.
        - The lpoptions command didn't set options properly when
          using the default printer.
        - Added ConfigFilePerm and LogFilePerm directives.
        - Increased maximum size of MIME types to IPP_MAX_NAME
          to allow for longer printer names.
        - No longer create remote printers when loading job
          history data.
        - The printer-make-and-model attribute wasn't set when
          the PPD file didn't contain a NickName attribute.
        - Now handle PPD files with translation strings longer
          than 80 bytes - they are truncated if they go over...
        - The scheduler didn't handle signals until after it
          loaded the configuration files the first time; this
          caused problems on some installations that would
          restart the scheduler as the system booted into run
          level 3.
        - Now throttle broadcasts like we do for polling.
        - Fixed a bug in the reading of PPD files using CR's
          instead of CR LF's or LF's.
        - The scheduler would crash if cupsd.conf contained a
          BrowseProtocols line with no protocols listed.
        - The HTML job operation templates now link back to the
          destination printer or class.
        - The serial backend now detects USB serial devices.
        - The LPD mini-daemon (cups-lpd) now passes the
          job-originating-host-name attribute to the scheduler
          (cupsd).
        - Updated the IPP backend to reconnect after downgrading
          from IPP/1.1 to 1.0, and when sending requests to HP
          JetDirect interfaces that don't support HTTP
          Keep-Alive like they should.
        - Now pass NLSPATH and DYLD_LIBRARY_PATH environment
          variables, if defined, to CGI and job processes.
        - Removed the pstoraster filter (based on GNU
          Ghostscript 5.50) and now provide the raster "driver"
          and patch file necessary to use the current GNU
          Ghostscript 7.05 release.
        - Removed unnecessary fonts and updated the Courier and
          Symbol fonts to the latest versions to better support
          non-ISOLatin1 text.
        - The text filter now always embeds the Courier and
          Symbol fonts to ensure that they contain the full set
          of glyphs.
        - The lp and lpr commands now only override the SIGINT
          handler if it is not being ignored (patch from Robert
          Ambrose for some interactive software that catches
          SIGINT and will gracefully cancel the print...)
        - The PostScript image filter (imagetops) now supports
          printing CMYK images using the CMYK colorspace.
        - The image filters now support CMYK JPEG files, and
          correctly handles the inverted files from Photoshop
          (which seems to save RGBW data, not CMYK...)
        - Added a "check" target to the top-level makefile to
          conform with GNU standards (same as "test").
        - The IPP code didn't always map the POSIX locale "C" to
          the proper IPP language code.
        - The cupsaddsmb program was updated to use the
          setdriver command instead of addprinter.
        - Banner pages were not handled properly for implicit
          classes.
        - When tunneling to a remote system using SSH, the
          printer URIs for local printers on the remote system
          did not reflect the correct port number.
        - The Allow, Deny, BrowseAllow, BrowseDeny, and
          BrowseAddress directives now support the network
          interface names "@LOCAL" and "@IF(name)" for access
          control and browsing based on the current interface
          addresses instead of fixed names or IP addresses.
        - The texttops filter did not properly recognize the
          "nowrap" (wrap=false) option.
        - The InstallableOptions group name in a PPD file is now
          translated separately (CUPS_MSG_OPTIONS_INSTALLED) so
          that UIs can accurately detect the presence of this
          group.
        - The scheduler no longer keeps job history data for
          remote printers on the client (just on the server.)
        - The parallel and USB backends now retry if the backend
          detects that the printer is not connected to the
          system (rather than stopping the queue...)
        - The network backends now retry if the backend detects
          that the printer is not connected to the network or is
          unreachable (rather than stopping the queue...)
        - The cupsGetDests() function no longer lists options
          and instances for printers that no longer exist.
        - The scheduler now converts the document language to
          the correct LANG string.
        - The cupsaddsmb program now supports alternative CUPS
          and SAMBA server names.
        - The PostScript filter now supports the Orientation
          comment and rotates the page as needed automatically.
        - Revamped the makefiles slightly to use automatically
          generated dependencies.
        - Build fixes for OS X.
        - The TIFF reading code depended on the newest version
          of libtiff; now conditionally compile that portion of
          the loader.
        - The PPD code now decodes all JCL options in the
          JCLSetup group, not just those options that start with
          the prefix "JCL".
        - The backends now read print data using the read()
          system call to ensure that the current page is printed
          while the next page is being processed.
        - The pdftops filter did not support shading type 3
          (radial fill) for the "sh" operator.
        - The cups-polld program now throttles the local
          broadcasts of polled printers and classes so that the
          local system is not overwhelmed with hundreds of
          printers and classes all at once.
        - Updated the serial backend to support 230,400 baud for
          the Linux PPC port.
        - The cupsGetJobs() function wouldn't report completed
          jobs that did not have a document-format attribute
          value.
        - The cupsEncodeOptions() function now maintains a table
          of known boolean and numeric options, and encodes all
          other options as strings.
        - Now add a newline before the end-of-page code in the
          PostScript filter; this fixes a problem with files
          that don't end with a newline.
        - The image filters looked for the "orientation" option
          instead of the correctly named "orientation-requested"
          option.
        - The cupsEncodeOptions() function now handles mixed
          integers and ranges.
        - New translation guide for developers to provide native
          language support for CUPS.


CHANGES IN CUPS V1.1.14

        - The ippRead() function did not verify that the
          attribute name length or string with language value
          was not larger than the read buffer.
        - The scheduler set the signal handlers before loading
          the configuration files the first time; this prevented
          the RunAsUser directive from blocking server reloads.
        - Added Swedish message catalog.
        - The parallel backend now recognizes the /dev/printers
          device directory under Linux 2.4.x.
        - MacOS X fixes.
        - The cupsaddsmb utility sent the server name after the
          user information when executing the rpcclient program.
          This caused problems with some versions of SAMBA
          2.2.x.
        - The IPP backend did not pass the requesting user name
          when checking on the print job status. This prevented
          it from waiting for the job to complete when
          communicating with some IPP implementations that
          require it.


CHANGES IN CUPS V1.1.13

        - The lpstat command did not report jobs submitted to
          regular printer classes.
        - The texttops filter didn't use sufficient precision
          when positioning text with some values of cpi and lpi.
          This could cause the alignment of text to stray.
        - cupsGetDests() didn't merge the options from the
          /etc/cups/lpoptions file with ~/.lpoptions - options
          in ~/.lpoptions overrode them completely.
        - Added support for KOI8-R and KOI8-U character sets,
          and added several Russian message catalogs.
        - The scheduler put the wrong timezone offset in the log
          files (e.g. +0500 instead of -0500 for EST...)
        - The scheduler did not ignore trailing whitespace in
          *.convs files.
        - The scheduler now forces all processes to exit (kill
          -9) when it is stopped.  This prevents parallel and
          USB devices from running in the background after cupsd
          goes away.
        - The cupsParseOptions() function didn't skip trailing
          whitespace after quoted values.
        - More changes to support CUPS on OS/2.
        - Added Simplified Chinese message catalog.
        - Added PAM support for IRIX.
        - The cupsGetPPD() function didn't remove the @server
          portion of the printer name, and since it would
          connect immediately to the remote server instead of
          the local server, the printer would not be found.
        - Classification and page labels were not rotated to
          match the page orientation.
        - Now set the TCP "no delay" option on network
          connections to improve performance/response time.
        - Improved the IRIX printing tools support with patches
          from Andrea Suatoni.
        - Added a new PrintcapGUI directive to specify the GUI
          option panel program to use for the IRIX printing
          tools support.
        - The cupsGetDests() function did not check to see if a
          user-defined default printer (set via lpoptions) still
          existed.
        - The pstops filter no longer assumes that the default
          dictionary is writable when doing N-up processing.
        - The pstops filter now supports printing N-up with the
          page-set option.
        - The imagetoraster filter now supports direct printing
          of CMYK image data without conversion/correction.
        - The IPP backend now reports printer state/error
          conditions when possible (toner low, media empty,
          etc.)
        - The lpstat command now supports the (undocumented)
          IRIX -l option ("-lprintername") for a compact job
          listing for a printer.
        - The lpstat command now includes printer date/time
          information in the output (always Jan 01 00:00) to
          make third-party tools happy.
        - The text filter now supports non-integer cpi and lpi
          values.
        - The Margins field in the CUPS raster header was not
          initialized by the pstoraster filter.
        - Added --with-optim="flags" option to configure script.
        - Updated the Italian message translations.
        - Updated the cups.list file to install the correct
          files.
        - The pstoraster filter accessed the third element of a
          2 element array.
        - The scheduler did not setup a status pipe for polling
          processes, so error messages went to whatever file
          descriptor 2 was pointing to when they were started.
        - The httpMD5Final() function didn't put a colon between
          the password and nonce strings.
        - The pstops filter did not default to Binary data for
          "%%BeginData:".
        - The pstops filter did not stop processing when a line
          containing a CTRL-D is seen.
        - The scheduler no longer replaces the JobSheets values
          from the printers.conf and classes.conf files with the
          classification level, if set.  This way the original
          banner settings are preserved when classification
          levels are changed or turned off.
        - The serial backend didn't drain the output queue, nor
          did it restore the original settings.
        - Updated the default system group under MacOS X.
        - If no SystemGroup was defined in cupsd.conf, the
          system default group was not used.
        - The cups-lpd mini-daemon now supports LPD clients that
          send multiple control files.
        - httpConnectEncrypt() now always uses encryption for
          connections on port 443, since port 443 is reserved
          for the "https" scheme.
        - Group authentication via certificates did not work
          from the web interface for accounts other than
          "root".       
        - The serial port backend did not clear the OPOST
          option, which could cause problems with some printers.
        - The cups-lpd mini-daemon didn't lookup the client IP
          address properly.
        - The parallel backend now identifies the polled and
          interrupt-driven devices under *BSD.
        - The scheduler allowed the "always" encryption mode
          inside a Location, which is not valid.
        - The CUPS startup script now checks for the timezone
          information under Linux.
        - Now also map the sides attribute to the JCLDuplex
          option (if present) in PPD files.
        - Updated pdftops to Xpdf 0.93a.
        - Added support for MD5 passwords under Slackware.
        - Added new AuthType BasicDigest that does Basic
          authentication using the MD5 password file managed by
          the lppasswd command.
        - The banner page attribute substitution code now
          retains {name} sequences in banner files when the
          named attribute is undefined.  Use {?name} to
          conditionally substitute an IPP attribute.
        - The scheduler now ensures that the ServerRoot
          directory and configuration files are owned by and
          writable by the User and Group in cupsd.conf.
        - The USB backend now lists all USB printer devices
          regardless of whether a printer is connected or not. 
          This allows new USB printers to be connected without
          restarting cupsd.
        - Added some more minor performance tweeks to the IPP
          protocol code to reduce copying and array indexing.
        - The cupsaddsmb utility now uses the -c option with
          smbclient and rpcclient to avoid the read length limit
          for commands on the standard input.
        - Added an include file to the CRD handling code in
          pstoraster so that it would compile properly on 64-bit
          pointer platforms...
        - The cups-config script reported the wrong version
          number.
        - The cups-config script was installed in $(bindir)
          instead of $(BINDIR).
        - The init script did not correctly check for a running
          cupsd under IRIX 5.x.


CHANGES IN CUPS V1.1.12

        - Added "Polish" to the list of known languages for PPD
          files.
        - Added missing directory definition to cups-config.
        - The CUPS-Move-Job operation did not set the
          destination type for the new destination.
        - The CUPS-Add-Printer operation did not support the
          allow=all or deny=none values to clear the per-user
          printer ACLs.
        - The SetPrinterAttrs() function did not handle invalid
          PPD files that were missing the required NickName
          attribute.  It now looks for NickName, ModelName, and
          then substitutes the string "Bad PPD File" for the
          printer-make-and-model attribute.


CHANGES IN CUPS V1.1.11

        - Added support for embedded TrueType fonts in PDF
          files.
        - Added support for PostScript functions in PDF
          files.
        - Added new "cupsaddsmb" utility for exporting
          CUPS printer drivers to SAMBA/Windows clients.
        - Added preliminary support for Darwin/MacOS X.
        - The CUPS-Add-Printer operation no longer allows
          arbitrary scheme names in device URIs to be used - it
          now restricts the available schemes to those found in
          the device list (lpinfo -m).
        - The ippRead() and ipp_read_file() functions could not
          handle more than IPP_MAX_VALUES (100) values in a
          1setOf attribute.  These functions have been updated
          to dynamically allocate more memory as needed, and the
          IPP_MAX_VALUES constant now represents the allocation
          increment.  [this caused some versions of the
          GIMP-print drivers to fail since the number of media
          options exceeded 100...]
        - The scheduler could crash when BrowseShortNames
          was set to "No".
        - The scheduler did not prevent MaxClients from being
          set to 0, which could cause the scheduler to go in an
          infinite loop when accepting a request.
        - Made some performance optimizations in the ippRead()
          functions to make IPP request/response processing
          faster.
        - The accept/reject/enable/disable command did not
          support properly support the "-h" or default
          server name.
        - The scheduler did not save the quota configuration
          when the job-quota-period attribute was set to 0.
        - The LPDEST and PRINTER environment variables did not
          support printer instances.
        - The text filter now handles more types of boldface and
          underline formatting.
        - The cupsTempFd() function did not fail if the
          temporary directory did not exist; this would cause it
          to loop indefinitely instead of returning an error
          (-1).
        - Stopping (disabling) a printer class did not stop jobs
          from printing to printers in that class.
        - The cupsGetDests() function was sending the
          requested-attributes attribute as a name instead of a
          keyword; this caused a serious performance problem on
          slower systems since more information had to be
          transferred from server to client.
        - The web interfaces did not always quote < and & in
          things like the job title.  This had the potential for
          browser-based security violations (on the browser's
          machine); bug report from SuSE.
        - The scheduler now treats unauthenticated usernames as
          case-insensitive when doing quota and allow/deny
          processing.
        - The lp command sent the "request ID is ..." message
          to stderr instead of stdout...
        - The PostScript filter (pstops) now handles EPS files,
          adding a showpage command to the files as needed.
        - The configure script checked for the <stdlib.h> header
          file before the JPEG libraries; since the JPEG headers
          can define HAVE_STDLIB_H, the configure check would
          cause the JPEG check to fail on some systems.
        - The scheduler now supports localized banner files,
          using the subdirectory approach, e.g. the "es"
          subdirectory under /usr/share/cups/banners is used for
          the Spanish banner files.
        - Updated the scheduler so it knows the correct
          language abbreviation to use for all supported
          PPD LanguageVersion values.  The new code also
          supports country codes as well, so "English-GB"
          maps to the "en_GB" locale.
        - The cups-lpd mini-daemon did not support
          anonymous printing (no username specified).
          While the username is REQUIRED by RFC-1179,
          MacOS clients do not send the REQUIRED username
          information when printing via LPD.
        - Added many warning and informational messages
          to cups-lpd where they were missing.
        - Added Czech message file contributed by SuSE.
        - The cups-lpd mini-daemon now returns a non-zero
          status if an invalid destination or job ID is
          provided.
        - The scheduler did not honor the KeepAlive setting in
          cupsd.conf.
        - Increased the size of the file read/write buffers to
          32k.
        - *BSD static library creation fixes.
        - Use mkstemps() instead of tmpnam() in pdftops whenever
          possible.
        - Added httpGetHostByName() function as a wrapper around
          gethostbyname() - some implementations of this
          function do not support IP addresses (e.g. MacOS X.)
        - Added casts to all printf's of file lengths, since
          there is currently no standard way of formatting long
          long values.
        - The client filename field was not cleared in all
          instances, resulting in old form data being submitted
          to CGIs.
        - The httpConnect*() functions now try all available
          addresses for a host when connecting for the first
          time.
        - The pstoraster filter would "lose" all drawing
          commands when the PageSize was set but the printer
          bitmap was  not reallocated.  This was most noticeable
          with the output from StarOffice 6 beta and would
          result in a blank page being output...
        - The IPP backend was sending a PAGE comment even when
          printing the output from a filter (it should only send
          page comments when printing files directly...)
        - The pdftops filter didn't properly map glyph names of
          embedded Asian TrueType fonts.
        - Changed the CUPS startup script to look for a program
          named "cupsd", not just any program with "cupsd" in
          the name (this caused the apcupsd UPS monitoring
          daemon to be stopped/restarted...)
        - The CUPS-Move-Job operation did not change the
          internal destination name for held jobs, so moved (but
          held) jobs would still show up as queued on the
          original destination.
        - The cups-polld program didn't send the
          requested-attributes attribute in the
          CUPS-Get-Printers and CUPS-Get-Classes requests, which
          made it use more CPU and bandwidth than required.
        - The scheduler and CUPS API incorrectly added a
          job-sheets-default attribute for remote printers. This
          caused banner pages to be omitted from client system
          prints.


CHANGES IN CUPS V1.1.10-1

        - Minor fixes to the filter, systemv, and template
          makefiles to install files properly.


CHANGES IN CUPS V1.1.10

        - Added a driver for DYMO label printers.
        - Added new ClassifyOverride directive to allow users
          to override the classification of individual jobs.
        - Added new BrowseProtocols directive to control which
          browse protocols are used (currently CUPS and SLP).
        - Added SLPv2 support (thanks to Matt Peterson for
          contributing the initial implementation for CUPS.)
        - Adding a raw printer on a remote CUPS server now
          correctly redirects PPD file requests to the remote
          server.
        - The serial backend now limits writes to 1/10th
          second worth of data to avoid buffer overflows
          with some types of flow control.
        - The scheduler did not properly process PUT requests,
          so configuration files could not be uploaded to the
          server.
        - The scheduler did not strip trailing whitespace on
          lines in the configuration files.
        - The httpWrite() function did not transition the PUT
          request to the HTTP_STATUS state to get the status
          from the server.
        - The scheduler did not properly handle trailing null
          ("-") filters when testing a driver that sent data
          to the file: pseudo-backend.
        - The IPP backend now only sends a document-format of
          "application/vnd.cups-raw" when printing to another
          CUPS server using a local printer driver or interface
          script.  Previously the job's document format was
          used, which was incorrect.
        - The lpadmin command didn't use the ppd-name attribute
          with the -m option; this prevented the use of the
          "raw" model from the command-line.
        - The pstoraster filter output draft (1-bit) 6-color
          output in the wrong order; this resulted in yellow
          being printed instead of black on Stylus Photo
          printers.
        - The pdftops filter did not have the Japanese and
          Chinese text support compiled into it.
        - The IPP and AppSocket backends did not clear the
          "waiting for print job to complete" status message,
          which caused some confusion... :)
        - The serial backend now opens the port in "no delay"
          mode to avoid DCD detection problems with some OS's.


CHANGES IN CUPS V1.1.9-1

        - The configure script did not substitute the
          correct user and group names.
        - The configure script did not use the full path
          to the install-sh script when it was used.
        - The pstoraster filter did not correctly support
          DuplexTumble mode for printers that used flip
          duplexing.
        - The cups.list.in file was missing from the
          distribution.
        - The New DeskJet series driver did not use the
          correct OrderDependency for the Duplex option.
        - Use read() instead of fread() to read piped
          print files in lpr/lp.  This avoids a bug in the
          HP-UX 10.20 fread() function.
        - Updated the pstoraster filter to use the MIPS_FIXADE
          system call under IRIX to fix bus error problems on
          R12000 processors (Ghostscript is not 64-bit clean...)
        - Some Xerox PPD files (most notably the Phaser 790)
          have illegal whitespace in the option keyword in the
          OpenUI line.  This caused the PageRegion option to not
          be recognized properly for the Phaser 790.


CHANGES IN CUPS V1.1.9

        - Revamped the configure script to use a modular
          approach for the various tests.
        - Added --with-openssl-* options to properly reference
          the OpenSSL libraries in DSOs.
        - Added --with-cups-user and --with-cups-group
          options to specify the default user and group for
          CUPS.
        - Added AIX shared library support.
        - Added AIX device discovery for the serial and
          parallel ports.
        - Now use install program or script to install
          directories, files, and symlinks.
        - Updated pstops filter to use strict handling of EPS
          files embedded in a PostScript document.  The %%EOF
          handling in 1.1.8 caused some dvips files not to
          print.
        - Fixed yet another memory allocation bug in pstoraster
          that would cause it to crash.  This fix also ensures
          that all memory allocations are done on (at least) a
          64-bit boundary.
        - Fixed Digest authentication - httpGetSubField() didn't
          skip the Digest keyword.
        - The scheduler did not properly handle Digest
          authentication with the new multiple-group support.
        - The scheduler did not allow usernames that were
          not in the UNIX password file to be used for Digest
          authentication from passwd.md5.
        - The scheduler could not scan PPD files that only used
          a carriage return (i.e. MacOS PPD files); the new code
          is also about 40% faster, so servers with thousands of
          PPD files should start much faster now.
        - The scheduler now stores the PPD file size and
          modification times in the ppds.dat file, so it can now
          incrementally update the PPD database from the model
          directory, resulting in significantly faster startup
          times.
        - The lpinfo command did not return a non-zero status
          code if an error occurred.
        - Fixed a bug in the scheduler's UpdateJob() function.
          Basically, all jobs shared the same status buffer, and
          the "buffer start" pointer could point to 1 byte
          before the beginning of the buffer.  The new
          implementation uses a separate buffer for each job and
          eliminates the buffer start bug.
        - The IPP backend would send N copies of a document if
          the receiving device didn't support the copies
          attribute, even if the upstream driver already added
          the necessary commands to generate the copies.  This
          was most noticeable with HP printers where N * N
          copies would come out instead of N.
        - The PostScript filter (pstops) did not properly handle
          duplex printing on inkjet printers that provide this
          option.  Copies would be put on the front and back
          sides of the duplexed page, and the filter did not
          output an even number of pages.
        - The backends always caught SIGTERM after they
          connected to the printer.  This prevented raw jobs
          from being cancelled early.
        - The cupsSetDests() function now removes any printers,
          instances, and options that are not defined by the
          user or server.  This should prevent old system-wide
          options from being used in individual user accounts.
        - Updated the EPSON printer driver and added PPDs for
          the newer EPSON Stylus printers that only support the
          "ESC i" graphics command.
        - The lpadmin command didn't allow you to add remote
          printers to a local class.
        - The lpadmin command didn't allow you to set the
          options (quotas, etc.) for a class.
        - The scheduler did not load or save the
          job-sheets-default attribute for classes.
        - The scheduler did not automatically recreate remote
          printers that were part of a class.
        - It was possible for a printer class to list the same
          printer more than once.
        - The scheduler now makes a backup copy of classes.conf
          and printers.conf before writing the new file.
        - The lppasswd program incorrectly asked for a new
          password when deleting an existing MD5 password
          account.
        - The scheduler did not match "/printers/name.ppd"
          against a location of "/printers/name".
        - The client code did not always handle HTTP encryption
          upgrades properly.
        - The client code now caches the last Digest password so
          it can retry using a new resource path or nonce value,
          which are included in the MD5 sum sent to the server. 
          This should eliminate unnecessary password prompts
          when using Digest authentication.
        - The lppasswd command didn't have a man page.
        - Updated the PJL detection rules to allow the universal
          escape to occur anywhere in the first 128 bytes of the
          file.
        - The cups-polld program would poll servers continuously
          with no delay if there was an error contacting the
          server.
        - The IPP backend would send an empty job-name or
          requesting-user-name attribute if the corresponding
          job attribute was an empty string.  While this is
          allowed by the IPP specification, some HP JetDirect
          implementations return a client-error-bad-request
          error if an empty name attribute value is received.
          The new code only sends these attributes if they are
          not the empty string.
        - At least some versions of the HP JetDirect firmware
          do not correctly implement IPP.  Added additional
          checks to the IPP backend to eliminate extra,
          unsupported attributes which should normally be
          ignored by a compliant IPP device.
        - The scheduler did not copy the complete list of
          supported file types into the
          document-format-supported attribute. This caused
          clients to not send the local file type (such as
          application/vnd.cups-raw for raw print files) and the
          corresponding bad output in some cases.
        - The scheduler did not fully copy attributes from a
          set-job-attributes request - string attributes were
          only referenced, which could cause cupsd to crash
          or behave irratically.
        - The lp command didn't send the right value for the
          job-hold-until attribute when "-H resume" was
          specified.
        - The IPP backend now returns as soon as a job is
          completed or reported as "pending-held".
        - Added new ImplicitAnyClasses and HideImplicitMembers
          directives to the cupsd.conf file to make implicit
          classes more usable/transparent to the user.
        - Clients can now (with the appropriate authentication)
          retrieve and update the server configuration files
          using HTTP GET and PUT requests.
        - The web interface didn't allow you to modify the
          location or description of the printer.
        - The pdftops filter now uses its own temporary file
          function to work with PDF files using LZW compression
          (which use the uncompress program or gunzip)
        - The SystemGroup directive now supports specification of
          multiple groups.
        - Added new Include directive to cupsd.conf, a la
          Apache.
        - Added new pseudo-driver/PPD called "raw" that can be
          used to create/convert a raw queue.  This also allows
          raw queues to be created in the web interface.
        - The pdftops filter didn't handle image objects that
          used JPEG and Flate compression together.
        - The pstops filter counted pages wrong when using the
          N-up and even/odd printing options.  This prevented
          the page-ranges option from working properly.
        - Added another fix to pstoraster for a bus error
          condition caused by a lack of parenthesis in the
          Ghostscript code.
        - Added new "natural-scaling" option which scales the
          natural size of the image (percent of natural image
          size instead of percent of page size.)
        - The lppasswd program is now setuid to the CUPS user
          instead of root.
        - The PPD functions did not allow for PPD files that
          defined the page sizes and margins before the page
          size options.
        - The mime.types file now checks for the PJL "LANGUAGE =
          Postscript" command for PostScript files.
        - The scheduler did not truncate file: output files.
        - The PPD file reading code did not handle options with
          raw quotes (") in the human-readable names.
        - The pdftops filter now remaps the space character when
          (bad) PDF files contain a .notdef glyph for the space
          character.


CHANGES IN CUPS V1.1.8

        - Updated configure script to check for /etc/pam.d and
          to only set PAMDIR if it exists.
        - Updated spec file to generate separate cups-pstoraster
          package for pstoraster.
        - The spec file wasn't setting LOGDIR in the install.
        - The scheduler might restart a stopped printer after
          stopping a print job. Thanks to Florent
          Guiliani for finding this bug!
        - The init script showed run level 0 for the Red Hat
          chkconfig program.  This is incorrect because Red Hat
          doesn't use run level 0 for shutdown scripts.
        - The IPP backend did not handle the
          client-error-not-found error when checking the status
          of the job that was sent.  This caused remote queues
          to stop on client machines when the server had job
          history disabled.
        - Added httpConnectEncrypt() function to avoid
          performance penalty for setting up encrypted
          connections initially.
        - Use httpConnectEncrypt() in all client apps and in the
          CUPS API to ensure consistent usage of encryption
          throughout.
        - Jobs weren't queued to remote classes (fix from
          Richard Begg.)
        - AIX changes from Richard Begg.
        - Fixed the pstops fix for GNOME output - no longer use
          the page numbers in the %%Page: comment since GNOME
          puts a filename instead (!?@!#?!).  There is still an
          issue with N-up printing since GNOME defines its fonts
          in the first page instead of the document setup section
          (pages must be independent according to the DSC spec)
          People with GNOME printing problems should consult bug
          #54489...
        - The imagetops filter produced PAGE: messages when
          generating PostScript for a non-PostScript printer
          (only affects page-label and Classification
           options.)
        - The updated pdftops filter was looking for an options
          file called xpdf.conf instead of pdftops.conf.
        - The scheduler would not force the default job sheets
          for printers to the current classification setting.
        - Added a new ippFindNextAttribute() function to the
          CUPS API.
        - ppdEmitJCL() now strips any leading path info from
          the title string.  This is only an issue for non-CUPS
          clients that don't do this already...
        - Other pstops fixed from Helge Blischke for printing
          non-conforming documents.
        - The MaxJobs parameter was not reset when loading the
          cupsd.conf file.


CHANGES IN CUPS V1.1.7

        - Configuration script changes, including new
          "--with-docdir=/dir" option to relocate CUPS
          documentation and web content according to your
          favorite version of the FHS.
        - Documentation updates for encryption, SLP, etc.
        - New Software Test Plan and automated test script to
          test CUPS prior to installation.
        - All scheduler configuration files are now case
          insensitive to match Apache.
        - Added support for Apache ListenBackLog, Require,
          Satisfy, <Limit>, <LimitExcept>, and LimitRequestSize
          directives.
        - Added support for all Apache log levels...
        - Added support for "double" HostNameLookups.
        - Added new "RunAsUser" directive to support non-root
          configurations on the standard (priviledged) ports.
        - Added support for non-root invocation of the lpd
          backend (does no reserve a priviledged port, which
          might not work with some LPD servers...)
        - Added new PrintcapFormat directive to control the
          output format of the printcap file (BSD or Solaris
          formats are supported at present.)
        - The CUPS directory service routines now handle
          ECONNREFUSED errors gracefully rather than shutting
          all browsing off.
        - ippErrorString() now returns the recommended error
          messages from the IPP/1.1 Model and Semantics
          document.
        - Fixed a minor IPP compliance issue with responses
          to requests without the attributes-charset or
          attributes-natural-language attributes.
        - Sun fix: need httpFlush() call for chunked IPP
          requests in cupsDoFileRequest().
        - httpConnect() now looks up "localhost" by name and
          by address (127.0.0.1) for users the go to the
          trouble of removing the required localhost entry
          in /etc/hosts or on their DNS server...
        - Added support for Linux 2.4.x devfs parallel port
          filenames (/dev/parallel/N).
        - cupsDo[File]Request() and cupsGetPPD() no longer
          block trying to reconnect to a crashed or inaccessable
          server.
        - Added new ppdEmitJCL() function to better handle
          PJL commands from PPD files.
        - A bug in UpdateJob() would cause the scheduler to
          consume 100% CPU until another request was submitted.
        - The cancel command did not support the "-" option to
          cancel all jobs on all printers.
        - The cancel and lprm commands did not support cancelling
          the next/current job in the queue.
        - The pdftops and pstoraster filters were using unsafe
          temporary file functions; while this is not a problem
          in normal configurations (the CUPS temporary directory
          is restricted), they now use the cupsTempFd() function.
        - The mime.types file was missing the recognition rule
          for Sun Raster images.
        - The admin CGI was passing a printer make string to
          ippSetCGIVars() that was being replaced in that
          function.
        - "lpoptions -l" would resave the options...
        - The EPSON drivers now send the "end packet mode"
          command when printing to USB devices.
        - The scheduler initialized certificates before loading
          the cupsd.conf file.
        - The scheduler used /dev/random to collect random data,
          which could block if insufficient entropy information
          had been collected by the kernel.  Now use
          /dev/urandom.
        - Fixed a bug in the whitespace skipping code in
          httpGetSubField().
        - The LPD backend now supports a new "order" option:
          "lpd://server/queue?order=control,data" (default) and
          "lpd://server/queue?order=data,control".
        - The scheduler enforced a 30 second timeout on all
          clients regardless of the Timeout directive and if a
          CGI was currently running.
        - cupsParseOptions() now sets boolean options to
          option=true or option=false.
        - The "percent complete" calculations in the LPD backend
          could overflow on large files, causing the percentage
          to wrap to 0 every 40MB or so.
        - Fixed a memory reallocation bug in pstoraster that
          could cause it to crash.
        - The LPD backend now sanitizes the job title to avoid
          potential problems on remote LPD servers.
        - The lp command did not send the requesting-user-name
          attribute when altering a job.
        - The pstops filter did not handle PostScript files with
          lines longer than 8191 bytes.
        - The scheduler no longer uses inet_addr() to convert IP
          addresses in dot format (mmm.nnn.ooo.ppp) to the
          32-bit format, since it will not work for IPv6
          addresses.
        - New "Classification" directive to force labeling of
          the current classification on each page.
        - New "page-label" attribute to add per-page labels
          ("For Official Use Only", "Draft", etc.)
        - The scheduler now sets the HTTPS environment variable
          for CGI programs when a client connects using
          encryption.
        - Fixed a recursion bug in the scheduler that could
          cause cupsd to crash when a printer was removed.
        - The LPDEST and PRINTER environment variables didn't
          support instances.
        - Dropped the "file" backend from the device list that
          is reported, since it is only available for *testing*
          and should never be used in a production environment.
          The file: device can still be used, but it won't show
          up in the list of devices from lpinfo or the web
          interface.
        - Added support for /dev/lpa# parallel ports under *BSD.
        - Added META variables to the CGI header template to
          prevent caching of the results.
        - Fixed an unaligned memory buffer for the pstoraster
          clist states; this caused bus errors for some
          combinations of printers, drivers, and options.
        - Re-added black reduction for colorful colors; this
          helps to prevent dark colors from getting desaturated.
          (only used when converting RGB to CMYK)
        - Added two new directives - MaxJobsPerPrinter and
          MaxJobsPerUser - to allow an administrator to set
          the maximum number of pending jobs in a queue or
          submitted by a user.
        - The scheduler no longer stops a printer if it can't
          create the status pipe or run the filters or backend.
          This will allow heavily loaded servers to service
          clients or start print jobs as the load allows.
        - Fixed a bug in the Set-Job-Attributes code that could
          crash the scheduler (patch from Martin Zielinski)
        - cupsSetDests() did not quote option values with
          embedded spaces.
        - Added support for the Enable-Printer and
          Disable-Printer extension operations (same as
          CUPS-Accept-Jobs and CUPS-Reject-Jobs.)
        - The AppSocket and IPP backends now wait for the print
          job to be finished before exiting; this should prevent
          the loss of print jobs with older JetDirect firmware
          and make consecutive print jobs print faster.
        - The BMP loading code did not handle resolution values
          of 0.  This is a problem with BMP image files produced
          by the GIMP.
        - The HTTP Upgrade code (upgrade to TLS encryption)
          bypassed the authentication checks.
        - The HTTP Upgrade code did not send a 426 status code
          to the client and end the current request. This caused
          a race condition between the client and server for the
          upgrade to TLS.
        - Fixed a bug in the EOF and Trailer detection code in
          the pstops filter.
        - The imagetoraster filter did not add the margins to
          the custom page size in the raster header.
        - The imagetops filter did not adjust the custom page
          size to the size of the printed image.
        - The imagetops filter did not include DSC comments
          which are required by some printers.
        - The imagetops filter did not insert newlines in
          Base85 encoded output, causing files to contain
          lines longer than 255 characters (violation of the
          DSC).
        - Added support for the DeskJet 900 series duplexer
          and CRET color modes in the HP driver.
        - Added support for PPD-defined margins in the HP
          driver.
        - Fixed the debugging output from pstoraster - the
          font list was not terminated by a newline.
        - Some versions of the HP-UX pam_unix authentication
          module apparently do not pass the appdata_ptr argument
          to the conversation function, preventing the scheduler
          from authenticating users using PAM under HP-UX.  A
          workaround using a static variable has been added to
          address this problem.
        - Fixed a bug in the scheduler SortPrinters() function
          that could cause printers to disappear or the
          scheduler to crash when adding a printer.
        - Changed the pstops filter to not do per-page filtering
          if the file does not conform to at least version 3.0
          of the document structuring conventions.  This seems
          to "fix" printing with broken apps.
        - The image filters did not handle older TIFF files that
          lacked the samples-per-pixel and bits-per-pixel tags.
        - Added new cupsGetJobs() and cupsFreeJobs() functions
          to manage print jobs.
        - cupsEncodeOptions() would encode names of 0 length and
          cupsAddOption() and cupsParseOptions() would add names
          of 0 length.
        - The scheduler might block waiting for status messages
          after starting a new print job. Thanks to Florent
          Guiliani for finding this bug!


CHANGES IN CUPS V1.1.6-3

        - The configure script put the JPEG library before the
          TIFF library; this caused problems in some
          configurations since the TIFF library also supports
          JPEG compression of TIFF images.
        - Updated the configure script and makefiles to handle
          admin man pages with the "1m" extension (HP-UX, IRIX,
          Solaris, Tru64) and in odd directories (IRIX)
        - The updated cupsTempFile() function did not return
          the filename when called with a filename buffer of
          NULL (previously it used a static buffer.)
        - FreeBSD uses /dev/unlptN, but NetBSD and OpenBSD use
          /dev/ulptN.
        - DeletePrinter() didn't remove the printer from any
          classes it was a member of.
        - DeletePrinterFromClass() didn't preserve the
          implicit status of a class.
        - DeletePrinterFromClasses() didn't remove printers
          from implicit classes.
        - StartJob() didn't send the job-sheets, job-priority,
          and job-hold-until attributes to remote printers.
        - LoadAllJobs() was looking for job-sheets-completed
          instead of job-media-sheets-completed.  This would
          prevent accumulation of page data after a restart
          of the scheduler.
        - The pstops and imagetops filters now generate copies
          using the appropriate method for a Level 1, 2, or 3
          printer since some Level 2/3 printers don't support
          the /#copies variable anymore.
        - The man page for cups-lpd did not mention the "-o"
          option.
        - The IPP backend didn't handle version-not-supported
          errors and revert to IPP/1.0 (previously it only checked
          for a bad-request error)
        - Caldera fix: lpc now reports unimplemented commands as
          unimplemented, not invalid.
        - Caldera fix: lpq didn't recognize BSD lpq "-a" option.
        - Caldera fix: lpr didn't recognize BSD lpr "-1", "-2",
          "-3", "-4", "-q", or "-U" options.
        - RedHat fixes: patches to GNU Ghostscript
        - SuSE fix: temp file creation patch to GNU Ghostscript
          (pstoraster).
        - SuSE fix: remove cgi-bin/abort.c and cgi-bin/email.c,
          which are not used.
        - SuSE fix: missing NULL check in cgi_initialize_post().
        - SuSE fix: potential buffer overflows in
          cgi_initialize_string().
        - SuSE fix: potential buffer overflows in
          ippSetCGIVars()
        - SuSE fix: more NULL checks in ppdOpen(); also make
          sure that all memory is freed on error to avoid memory
          leaks.
        - SuSE fix: Exit from child if setgid() or setuid()
          fails.
        - SuSE fix: Added setgroups() calls after setgid() and
          setuid() calls.
        - SuSE fix: potential buffer overflows in httpEncode64()
          calls.
        - SuSE fix: potential buffer overflows in httpSeparate()
        - SuSE fix: potential buffer overflows in ippWrite() for
          bad input.
        - SuSE fix: potential nul skip in ppd_decode() for
          missing hex digits.


CHANGES IN CUPS V1.1.6-2

        - Added changes to support NetBSD startup scripts.
        - Added separate compiler options for pstoraster
          (Ghostscript) to avoid compiler-induced errors
          from Ghostscript's twisted code.
        - The mime.types file contained syntax errors.
        - Updated the *BSD USB device filenames to use
          the /dev/unlptN files so that the USB device
          is not reset prior to printing (causes print
          corruption on many printers)
        - Added new cupsTempFd() function to avoid serious
          security bug in glibc fopen() function.  The glibc
          fopen() function unlinks a file before creating it,
          which opens up possible symlink attacks.
        - Now reject 0-length names in add-printer and add-class
          requests.
        - Fix for pstoraster when ZLIB is not available.
        - cupsGetPPD() didn't reconnect when a HTTP connection
          was lost.
        - SuSE fix: httpConnect() didn't check that the
          value from gethostbyname() was a valid IPv4 address.
        - SuSE fix: httpConnect() didn't allow file descriptor 0
          to be used for a socket.
        - SuSE fix: ippRead() didn't confirm that all values in
          a set were numeric or string types.
        - SuSE fix: lppasswd race condition fixes.
        - SuSE fix: directive names could overflow buffer when
          reading *.conf files.
        - SuSE fix: HEAD requests for PPD files did not use the
          same logic as GET requests.
        - SuSE fix: possible buffer overflow when adding
          /index.html to requested directory name.
        - SuSE fix: possible buffer overflow when converting
          IPP attributes to string options for filters.
        - SuSE fix: creating file: device output with mode 0666
          instead of mode 0600.
        - SuSE fix: creating job info files with mode 0640
          instead of 0600.
        - SuSE fix: don't rely on snprintf() for including
          system name in log filenames.
        - SuSE fix: add bounds checking when copying quoted
          and hex strings.


CHANGES IN CUPS V1.1.6-1

        - Added configure check for getting the correct
          strftime() format string; %c is not Y2k safe,
          and %KC and NULL are not universally supported.


CHANGES IN CUPS V1.1.6

        - Fixed another possible DoS attack in httpGets()
        - Added check for "LANGUAGE = PCL" and "LANGUAGE =
          POSTSCRIPT" in mime.types.
        - Resolution options were not being passed into the
          filter programs properly.
        - The default compiler options for GCC no longer include
          "-g3", which apparently is deprecated in newer
          versions of GCC.
        - CheckJobs() could cause cupsd to crash if a job is
          cancelled in StartJob().
        - The printers.conf and classes.conf files are now
          written with restricted permissions.
        - The round-robin algorithm used by FindAvailablePrinter()
          had problems; fixes contributed by Joel Fredrikson.
        - If LoadAllJobs() is unable to determine the file type
          of a print job, assume "application/vnd.cups-raw".
        - The web interface now provides a job_printer_name
          value for any corresponding job_printer_uri value.
        - The cups-lpd mini-daemon now logs the client address
          and hostname as well as all commands and errors in the
          syslog file.
        - The IPP backend now detects the supported file formats
          and only specifies the document format if it is
          supported.  This makes IPP printing to network print
          servers and cards more reliable without affecting the
          capabilities of CUPS servers.
        - The time_at_xyz attributes are now converted to human-
          readable dates and times for the web interfaces.
        - The HP and EPSON sample drivers now correctly catch
          signals and eject the current page when a job is
          cancelled.
        - Fixed bug in CGI code - did not ignore control
          characters (e.g. newlines) in form data.  This caused
          sporatic web interface problems.
        - The file type logging code in the scheduler referenced
          the optional document-format attribute; the new code
          uses the resolved MIME type instead.
        - The client.conf parsing code now removes trailing
          whitespace.
        - The MaxJobs directive was being treated as a boolean
          instead of an integer.
        - The scheduler would not timeout remote printers if
          BrowseInterval was set to 0.
        - The lpadmin command now supports setting of options
          and user-level access control.
        - Added "-E" option to all printing commands to force
          encryption.
        - The client code did not consume the response to the
          OPTIONS request when switching to secure mode.
        - The scheduler did not output a Content-Length field
          when responding to an OPTIONS request.
        - Added documentation on using cups-lpd with xinetd
          to the man page.
        - The socket backend now starts retries at 5 seconds and
          increases the interval to 30 seconds.  This should
          provide faster printing when multiple jobs/files are
          queued for a printer.
        - The filters and backends no longer buffer output to
          stderr.  This should provide much more accurate status
          reporting.


CHANGES IN CUPS V1.1.5-2

        - Fixed configure check for OpenSSL to work with RSA
          code.
        - Added configure check for <sys/ioctl.h>, and use this
          check in backend/serial.c.
        - Updated configure script handling of data,
          configuration, and state directories to use datadir,
          sysconfdir, and localstatedir variables.
        - NetBSD uses different serial port filenames than
          FreeBSD and OpenBSD.
        - The pdftops filter didn't need some X-specific files.
        - The scheduler makefile doesn't do a chown anymore when
          installing (cupsd did this automatically on startup
          anyways)


CHANGES IN CUPS V1.1.5-1

        - There was a typo in the top-level Makefile
        - The top-level Makefile did not install an init script
          for run level 5. 
        - The configure script did not add the "crypto" library
          when checking for the OpenSSL library. 
        - The OKIDATA PPD files were missing. 
        - The config.h.in file defined the wrong version number. 
        - The serial backend did not define "funky_hex" under *BSD. 
        - Updated the Visual C++ project files and some of the
          CUPS API sources to compile under Windows again. 


CHANGES IN CUPS V1.1.5

        - Security updates - new default configuration does
          not broadcast printer information and only allows
          access from the local system.
        - EXPERIMENTAL encryption support - CUPS now optionally
          supports TLS/SSL encryption via the OpenSSL library.
        - Documentation updates.
        - Makefile/configure script updates.
        - The RPM spec file didn't work out-of-the-box under
          RedHat or Mandrake.
        - Minor code cleanup to remove extraneous compiler
          warnings.
        - cupsTempFile() was using %p for the temporary
          filename; this should have been %08x (just 8 digit
          hex)
        - Deleting a printer with active print jobs would still
          crash the server.
        - ippWrite() and ipp_write_file() didn't send the
          correct value length for name-with-language and
          text-with-language attributes.
        - Updated IPP code to support copied strings (that
          should not be freed); this provides slightly more
          efficient IPP server performance.
        - Updated PDF filter to Xpdf 0.91.
        - httpGets() could go into an infinite loop if a line
          longer than the input buffer size was sent by a
          client. This could be used in a Denial-of-Service
          attack.
        - The lpstat and CUPS API functions now request only the
          data required when getting the list of printer or
          class information.  This should improve performance
          with large numbers of printers on slower machines.
        - The scheduler was always enforcing the FilterLimit,
          even if FilterLimit was set to 0.
        - Updated the Linux USB backend to support Mandrake's
          /dev/usb/usblp# filenames.
        - The PRINTER and LPDEST environment variables did not
          override the lpoptions default printer.
        - The PPD read functions incorrectly included trailing
          characters (usually whitespace) after quoted string
          attributes.
        - The multiple-document-handling attribute handling code
          did not check for the correct value for collated
          copies (separate-documents-uncollated-copies).
        - The EPSON driver did not work with OKIDATA printers in
          EPSON emulation mode (needed change-emulation command)
        - The HP-GL/2 filter did not scale the plot properly in
          scale mode 2.
        - Added PPD files for 9-pin and 24-pin OKIDATA printers.
        - The httpSeparate() function didn't handle passwords
          that started with a number.
        - ippDelete() could free the character set string
          multiple times in name-with-language and
          text-with-language attributes.
        - The scheduler would access freed memory right after
          freeing it (for debug messages); these parts of the
          code have been reordered to avoid this situation
          which was causing sporatic errors and crashes.
        - The ppdClose() function didn't free all of the strings
          in the ppd_file_t structure.
        - The LoadAllJobs() function in the scheduler did not
          close the spool directory.
        - Changed all sprintf's that use string formats to
          snprintf's, even if the destination buffer is
          larger than the source string(s); this protects
          against buffer overflows caused outside of CUPS...
        - Changed all strcpy's to strncpy's between local and
          global variables, even if the destination buffer is
          larger than the source string; this protects
          against buffer overflows caused outside of CUPS...
        - The CUPS certificate functions didn't use the
          CUPS_SERVERROOT environment variable when set.
        - The directory services code was copying instead of
          comparing the remote printer info, resulting in
          unnecessary updates of the printer attributes for
          remote printers.
        - Added new mime.types rules to allow automatic raw
          printing of PCL and ESC/P files; PJL headers are
          parsed to differentiate between PostScript and
          PCL job files.  This should eliminate a lot of
          the reports of SAMBA printing problems due to
          the missing "-oraw" or "-l" options.
        - The mimeLoadType() function didn't handle the
          3-argument contains() function.
        - The LoadPPDs() function in the scheduler didn't
          properly set the alloc_ppds variable or handle a PPD
          database containing 0 printers.
        - The scheduler FindAvailablePrinter() function didn't
          use the same queuing logic as the CheckJobs()
          function.  This caused classes to stall if a remote
          printer was always busy.
        - Jobs are now assigned to printers in a class
          round-robin style.  This should prevent the first
          server in the class from bearing the brunt of the
          jobs.
        - The scheduler's LoadAllJobs() function didn't always
          restore remote printers for queued jobs on startup.
        - The serial backend didn't support the higher baud
          rates with the old termios interface. It now supports
          57600 and 115200 baud.
        - The serial backend now supports different types of
          flow control; previously it ignored the flow=XYZ
          option in the device URI.
        - The serial backend now supports DTR/DSR flow control,
          which is popular on dot-matrix printers (access with
          "flow=dtrdsr" in the device URI)
        - Added new job-originating-host-name attribute for
          jobs.  The new attribute provides the hostname or
          IP address of the machine that submitted the job.
        - The set-job-attributes code no longer allows read-only
          job attributes to be changed.
        - Expanded the click area for the navigation bar in the
          web interface.
        - Updated the lp and cancel commands to support all of
          the Solaris print options (some are simply ignored
          since they do not map)
        - Updated the scheduler to limit the number of file
          descriptors to the maximum select() set size.  This
          was causing problems on Solaris systems where the
          max FD count was increased beyond 1024.
        - The scheduler's LoadDevices() function was getting
          interrupted by the SIGCHLD signal handler; now ignore
          child signals while loading devices.
        - Added quota and allow/deny user support for printers
          and classes.
        - Removed black/CMY adjustment code from the PS and
          image file RIPs; it was interfering with some CUPS
          driver dithering code.
        - The lpc program stopped listing the queue statuses
          after the first active printer.
        - The cups-lpd program used an output format that the
          Solaris printing system did not understand.
        - Updated the lpq program to use the Solaris format
          except under Tru64 UNIX.
        - Some DEC PPD files incorrectly use "Off" for the null
          value in UI constraints. Added "Off" to the list of
          accepted null values.
        - Changed the *BSD define constants to __*BSD__ in all
          of the backends.
        - Added support for "lpstat printername", which is an
          undocumented feature in Solaris.
        - The HP-GL/2 filter now only sets the plot size if it
          is set in the plot file.
        - The lpmove command wasn't sending the requesting
          user name, causing it to always fail.
        - Updated the cupsTempFile() code to use GetTempPath()
          under Windows.
        - The cups-lpd mini-daemon didn't limit the number of
          data files accepted, didn't use cupsTempFile(),
          didn't handle control file job information in any
          order, and didn't free job options after printing
          a file.
        - The scheduler copy_banner() function did not
          explicitly set the owner and permissions of the banner
          files, which could prevent the banner pages from
          printing on some systems.
        - The lpstat program wasn't listing remote classes.
        - The scheduler did not verify that the printer-uri
          attribute was specified in all requests that required
          it.


CHANGES IN CUPS v1.1.4

        - Makefile and configure script fixes.
        - **** Changed the default Printcap setting **** to
          /etc/printcap. There are just too many people asking
          why application XYZ doesn't see their printers!
        - The web admin interface now displays an error if it
          can't get the list of printer drivers from cupsd.
        - The IPP backend was putting the copies option before
          the other job options were set. This caused the IPP
          request to contain attribute groups in the wrong
          order, which prevented remote printing.
        - Added checks in scheduler to free memory used for
          IPP requests and language information when closing
          a client connection.
        - Fixed the duplex option in the HP LaserJet driver.  It
          should now work with all LaserJet printers (and
          compatibles)
        - The add-printer web interface didn't initialize the
          "old info" data pointer, which caused random crashes
          on many OS's.
        - Fixed many page sizes defined in the Level 1
          compatibility file "gs_statd.ps" to match reality.
        - Fixed another bug in the setpagedevice "code" in
          Ghostscript.  It should now accept all standard
          Adobe attributes on all platforms.
        - Fixed pstoraster so that it reallocates memory for
          color depth changes as well as size/resolution
          changes.  This removes an ordering constraint on
          the color, page size, and resolution options in
          PPD files.
        - The IPP backend didn't use the job's character set
          when the destination printer supported it.  This
          caused problems when printing text files to other
          CUPS servers.
        - Updated the logic used to determine when to rebuild
          the PPD file database.  The scheduler now checks the
          dates and the number of PPD files (was just checking
          the dates.)
        - Updated the ippSetCGIVars() function (used by the
          web interfaces) to only filter valid string values.
        - The PostScript filter was scaling 2-up pages
          incorrectly.  This caused the edges of some pages to
          be clipped.


CHANGES IN CUPS v1.1.3

        - Makefile fixes.
        - RPM spec file changes.
        - Documentation updates.
        - Enabled pstoraster debug messages for everything
          (only logged when LogLevel set to "debug"...)
        - Changed the Input/OutputAttributes fix in
          pstoraster so that it works on all platforms.
        - The HP-GL/2 filter didn't set the right green
          color value in encoded polylines or text.
        - Updated the "fitplot" code to handle plot sizes
          specified as "PSwidth,length" and "PSlength,width".
        - Updated the Linux parallel and USB backends to open
          the device files prior to looking in /proc for
          autoprobe info. This makes sure that loadable device
          driver modules are in fact loaded...
        - Added new FilterLimit directive to limit the number
          of processing jobs/filters on a system.
        - set-job-attributes didn't change the job-state to
          held/pending when the job-hold-until attribute was
          specified.
        - set-job-attributes didn't save the new job attributes.
        - Now change the "requesting-user-name" attribute in
          requests from remote systems to "remroot" when an
          unauthenticated "root" user is sent. This can be
          changed using the new RemoteRoot directive in
          cupsd.conf.
        - The cancel-job, hold-job, release-job, and restart-job
          operations didn't log the authenticated username.
        - The cups-lpd mini-daemon now checks for a
          document-format option before forcing raw mode with
          filter mode 'l'.
        - The cups-lpd mini-daemon now supports "-o" options
          on the command-line (passed by inetd) to set global
          defaults for all print queues.
        - The pstops filter assumed that a file with a Trailer
          comment would also have an EOF comment.
        - Added new cupsSetPasswordCB(), cupsSetServer(),
          cupsSetUser(), and ippSetPort() functions to better
          support client applications (especially GUIs...)
        - The CUPS-add-class and CUPS-add-printer operations
          didn't reset the printer-name attribute on remote
          print queues that had to be renamed when a local
          printer was defined with the same name.
        - The lpoptions command now supports a "-r" option to
          remove options for a printer or instance.
        - The lpadmin and admin.cgi programs no longer allow
          class and printer names to begin with a number; this
          caused the command-line utilities to become confused.
        - The Linux USB backend now looks for both the parallel
          and usblp driver names in the device list.
        - Added a new FontPath directive to cupsd.conf, and also
          a "--with-fontpath" option for the configure script to
          specify alternate font paths for pstoraster.
        - The CUPS-move-job operation didn't update the
          job-printer-uri attribute.
        - The scheduler only looked up printers and classes by
          name in IPP requests, instead of using the full URI.
          This caused problems with KUPS and friends with
          remote printers.
        - The scheduler now handles better localization of
          hostnames (e.g. server is host.foo.com, remote is
          host.subfoo.foo.com, localized is not host.subfoo...)
        - The scheduler logging functions now use a common
          log file checking/rotation function (courtesy of
          Crutcher Dunnavant at Red Hat)
        - The scheduler could accept more client connections
          than it allocated for if more than one Port or Listen
          line was present in cupsd.conf.
        - Other minor scheduler performance tweeks.
        - The lpq and lprm commands didn't support the default
          printer set using lpoptions.
        - The lpoptions command now supports a "-l" option to
          list the printer-specific options and their current
          settings.
        - The web printer and class lists now show a link to the
          default printer or class at the top of the page.
        - The text filter now supports pretty printing of shell
          and perl scripts as well as C/C++ source files.
        - The top and bottom margins were reversed for landscape
          text printing.
        - The lpq and lprm commands didn't understand printer
          instances.
        - The scheduler only selected on the first 100 file
          descriptors instead of the maximum file descriptor
          limit.
        - The scheduler client, listener, and mainline functions
          now share code to disable and enable monitoring for
          new client connections.
        - The imagetoraster filter didn't support all of the
          required pagedevice parameters.
        - The serial backend now checks for 100 serial ports
          under Linux.
        - The scheduler used sscanf() to pull out the remote
          printer location, description, and make/model strings,
          but if any of these options was empty then sscanf()
          would stop processing.
        - Added "debug2" log level to provide a little less
          verbose debugging information at the "debug" level.
        - The scheduler would crash if you stopped a printer
          that was currently printing a job.
        - The scheduler incorrectly allowed jobs in the cancelled,
          aborted, or completed state to be cancelled.
        - The image filters did not load TIFF images properly
          for bottom-to-top and right-to-left orientations.
        - Added new cupsEncodeOptions() function to encode
          CUPS options as IPP job attributes.
        - The IPP backend, LPD mini-daemon, client commands,
          and CUPS API did not properly encode multiple
          option values separated by commas.
        - Added new scheduler malloc logging in debug mode
          (provides summary of total arena size, allocated,
           and free bytes once a minute)
        - The EPM-based distributions didn't install the
          correct symlinks for a few man pages.
        - Fixed a memory leak in the scheduler - wasn't
          freeing old filters when deleting or renaming
          printers.
        - The scheduler now queries the primary IP address
          for the name of the server and maps any incoming
          requests from that address to the server name.
          This fixes web admin mapping problems from
          server.domain.com to localhost.
        - The web printer modify interface now remembers
          the previous device and driver settings (except
          for serial ports.)
        - The job-k-octets attribute is now stored as part of
          the job attributes; this preserves the information
          after a job is completed when job file history is
          turned off.
        - Dropped option sub-group parsing code for the moment,
          since many Xerox PPD files abuse this feature in PPD
          files and don't follow the hierarchy rules.
        - Added new wrapper code around options so that duplex
          options for some HP printers don't prevent prints.
        - Added support for Digital UNIX/Tru64 UNIX/OSF/1 format
          for "lpstat -v" output.
        - Now show the URI for remote printers instead of
          /dev/null in "lpstat -v" output.
        - Creating classes and adding printers to a class with
          the lpadmin command didn't work.
        - The banner pages and test page should now format
          correctly in both portrait and landscape orientations.
        - Updated banner page substitution so that { can appear
          by itself without quoting.


CHANGES IN CUPS v1.1.2

        - Makefile/configure fixes
        - RPM spec file and EPM list file fixes
        - The cupsTempFile() function now uses a different
          algorithm for generating temp files and "reserves"
          them to avoid possible security exploitation.
        - Now use /dev/random (if available) to seed the random
          number generator for certificates.
        - The /var/spool/cups and /var/spool/cups/tmp directories
          were incorrectly owned by root; they are now owned by
          the filter user, typically "lp".
        - The scheduler now resets the permissions on the spool
          and temp directories as needed to match the filter
          user.
        - Now expose ppdCollect() as an externally callable
          function.
        - The image filters now support filtering from the
          standard input.
        - The imagetoraster filter now collects all printer
          options and job patch files and applies them to the
          page header as needed.
        - Added format and banner options to LPD backend.
        - The send-document operation didn't start a job
          immediately when last-document was true.
        - The set-job-attributes operation didn't correctly
          replace the current job-hold-until value.
        - Removed the option wrapper code from ppdEmit() and
          friends since it caused problems with Ghostscript
          and many PS printers.
        - Was setting TZ environment variable twice for job
          filters.
        - Added syslog logging in cups-lpd to aide in
          debugging problems.
        - The HP-UX parallel port backend did not list the
          available parallel ports on some systems (printf
          calling problem...)
        - The lp and lpr commands overrode user options if
          -d/-P were specified after -o.
        - The scheduler would crash with a */* filter.
        - Added support for a "default" filter for unknown file
          types.  The example provided in the mime.types and
          mime.convs file prints unknown files as if "-oraw" was
          specified for the job.  This functionality is disabled
          by default.
        - The "compatibility" mode fix for older backends did not
          work for smbspool.  Added a workaround for it.
        - The HP-GL/2 filter didn't perform the right pen scaling
          with some files and the "fitplot" option.
        - New Software Performance Specification document that
          describes the memory, disk, and CPU usage of all the
          CUPS software.


CHANGES IN CUPS v1.1.1

        - The pstoraster Makefile still referenced one of the
          old PDF filter files.
        - The filter Makefile used INSTALL_DATA instead of
          INSTALL_LIB to install the CUPS image library.
        - The administration CGI didn't work properly with
          network devices.
        - The BrowseACL variable was not updated after the
          cupsd.conf file was loaded.
        - The lpd mini-daemon didn't support printer instances.
        - Now use a default umask of 077 for child processes.
        - Now put temp files in /var/spool/cups/tmp for child
          processes and the root user, unless TMPDIR or TempDir
          is defined otherwise.
        - cupsGetPPD() no longer uses easy-to-guess filenames.
        - The CUPS-Delete-Class and CUPS-Delete-Printer
          operations now save classes.conf file as needed.
        - The lppasswd command wouldn't add a user.
        - The ppdOpen() function could cause a segfault if a
          0-length PPD file was read.
        - The image filters were not handling images with
          different X and Y resolutions properly.
        - The imagetoraster filter defaulted to RGB output
          instead of black output like pstoraster.
        - The pstops filter didn't handle binary data properly.
        - The pstops filter didn't handle copies properly for
          PS files lacking DSC comments.
        - The pstops filter now appends %%EOF to the end of
          documents if they don't have it.
        - The cupsGetPPD() function didn't work with remote
          printers lacking the @server in the name.
        - The configure script didn't work right when only
          --prefix was specified.
        - The ppdEmit() code now wraps all printer commands so
          that buggy PostScript printers will still print a file
          after receiving an option that isn't available.
        - Fixed the DeskJet margin bug, and disabled 600dpi
          color mode until it can be fixed.
        - The cupsAddDest() function didn't sort instances
          correctly in all cases.
        - The time-at-xyz attributes now expand to the date and
          time in banner files.


CHANGES IN CUPS v1.1

        - Documentation updates.
        - Configuration script updates.
        - Didn't map charset and language value strings to lowercase
          and _ to - as required by SLP and IPP.
        - ppdLoadXYZ() didn't add the list of available fonts to the
          ppd_file_t structure.
        - The text filter common code was freeing the PPD file data
          before it was used.
        - The text filter now embeds missing fonts.
        - The CGI interface now maps local access to the server to
          the localhost address.
        - The HP-GL/2 filter didn't use the specified (or default)
          color ranges, resulting in strange colors.
        - The HP-GL/2 filter didn't default to no input window, which
          caused unnecessary clipping of plots.
        - Integrated Xpdf's pdftops filter into CUPS, which is a
          lightweight and reliable replacement for Ghostscript's
          PDF support.
        - Removed all PDF support from Ghostscript.
        - Updated HP driver to set top margin; this seems to fix
          the offset problem seen on HP DeskJet printers.
        - Fixed dependencies on the ZLIB and JPEG libraries in
          pstoraster.
        - The lpr command wasn't using the lpoptions defined by
          the user.
        - The lpr command would segfault if the CUPS server was
          not running.
        - The top-level makefile was not installing the CUPS
          initialization script.  It now does so if it sees there
          is an init.d directory in /sbin, /etc/rc.d, or /etc.
        - "lpstat -v all" didn't work.
        - pstoraster would crash on some platforms doing the
          setpagedevice operator.
        - The web administration interface now allows you to set
          the default banner pages.
        - Images can now be positioned on the page using the new
          "position" option.
        - The AccessLog, ErrorLog, and PageLog directives now
          support "%s" to insert the server name.
        - Added a new BrowseShortNames directive to allow for
          short remote printer names ("printer" instead of
          "printer@server") when possible.
        - The scheduler could crash if given an invalid PPD file
          with no PageSize attributes.
        - Updated the serial, parallel, and usb backends to do
          multiple writes and ignore ioctl() errors as needed;
          this should fix problems with serial printing on old
          serial drivers and with the UltraSPARC parallel port
          driver under Solaris 2.7.
        - Now propagate LD_LIBRARY_PATH to child processes from
          cupsd.
        - New DataDir directive for installing in alternate
          locations.
        - New CUPS_SERVERROOT and CUPS_DATADIR environment
          variables to specify installation directories as
          needed.
        - Queued remote jobs recreate remote printers as needed
          when the scheduler is started.
        - Deleting a printer also purges all jobs on that
          printer.
        - Old job and control files that don't belong to a
          printer are automatically deleted.
        - Wasn't updating time-at-processing and
          time-at-completed attributes in job.
        - Didn't send required multiple-operation-time-out
          attribute in response to a get-printer-attributes
          request.
        - cups-lpd now supports options set with lpoptions.
        - The job-hold-until attribute is now provided with all
          jobs. For jobs that are not currently held the value
          is "no-hold".
        - The scheduler was not sending "unknown" values in IPP
          responses.
        - The lpoptions command now accumulates options from
          previous runs rather than replacing all options for a
          printer.
        - The IPP backend now switches to IPP/1.0 if a 1.1
          request fails.
        - The lpadmin and admin.cgi programs now validate new
          printer and class names.
        - The access_log file now includes the number of IPP bytes
          received in a POST request.


CHANGES IN CUPS v1.1b5

        - Documentation updates.
        - The pstoraster filter didn't compile without the JPEG library.
        - The cupsd server didn't support the HTTP OPTIONS request
          method.
        - Dropped the "CLOSE" method supported by the cupsd server.
          (not defined in HTTP specification)
        - Makefile/configure script fixes.
        - Missing the job-restart template.
        - Added IPP test suite for testing.
        - Missing IPP documentation from binary distributions.
        - Fixed multiple-document handling code when last-document
          not specified.
        - Added more checks to IPP requests to prevent bad requests
          from getting through.
        - Not all of the Ghostscript error output was being sent to
          stderr.
        - The PostScript filter now added PJL commands to set the
          job name and display string, if supported.
        - The scheduler would crash if the browse socket could not
          be bound. Now disables browsing if port 631 (reserved for
          IPP) is being used by a misbehaving daemon.
        - The USB backend now looks for the older Linux 2.2.x USB
          printer device filenames as well as the newer ones.
        - The IPP backend now uses the UTF-8 charset exclusively,
          since apparently only CUPS handles more than US-ASCII and
          UTF-8...
        - Wasn't quoting ( in PostScript banners...
        - Send-document requests with no document-format attribute
          could cause cupsd to crash.
        - Old jobs in the spool directory might cause cupsd to
          crash.
        - CUPS now supports all of the recommended job-hold-until
          keywords as well as name values of the form "HH:MM" and
          "HH:MM:SS".
        - Added placeholder pointer for TLS encryption to the HTTP
          connection structure.
        - Fixed the "fast poll" bug reported by DISA - the
          status pipe wasn't being closed for multi-file jobs.
        - Revamped put_params code in pstoraster to fix bitmap
          allocation bug with FrameMaker output.
        - Ripped out filename, etc. code from pstoraster as it
          is a potential security hole.
        - Added support for RIP_CACHE environment variable in the
          new pstoraster.
        - Fixed USB device filenames for Linux; now support new
          pre-2.4 devices (/dev/usb/lp#) and 2.2 devices
          (/dev/usblp#)
        - Fixed accept-jobs crash with classes.
        - Didn't include dot-matrix EPSON drivers in previous
          release.


CHANGES IN CUPS v1.1b4

        - Documentation updates.
        - Many makefile and configuration script fixes (should
          now compile better under *BSD.)
        - The MediaPosition attribute was being mishandled by
          GhostScript, causing the RIP to fail whenever a paper
          tray was selected.
        - The scheduler now logs the final line of log information
          from a filter, even if it doesn't end with a newline; this
          primarily affects GhostScript error output.
        - The scheduler was saving implicit classes, so after a few
          restarts you'll end up with AnyPrinter, AnyAnyPrinter, etc.
        - The JPEG autodetection didn't work with some JPEG files that
          came from digital cameras (JPEG but not JFIF); the new
          magic types should work with all images that the JPEG library
          can handle.
        - Fixed a bug in the new contains() MIME type rule that could
          cause cupsd to crash.
        - Switched to using strtol() in the MIME type code so that you
          can use hex, octal, or decimal constants as desired in the
          mime.types file.
        - Banner files are now treated as templates, allowing any type
          of file to be used as a banner.
        - Added a 30-second timeout to backend device reports so that a
          hung backend will not prevent the scheduler from starting.
        - Backends are once again terminated when jobs are stopped; the
          CUPS-supplied backends will stay alive until the downstream
          filters have had a chance to clear out old page data.
        - The charset lookup in the CUPS localization support was wrong
          (iso8859-x instead of iso-8859-x)
        - Changed the "cpNNNN" code page files to "windows-NNNN" to match
          the IANA registrations.
        - New PostScript banner pages.
        - Added Windows BMP and Alias PIX image file support to the image
          filter.
        - The PNG reading coded didn't free all of its buffers.
        - Added Digest authentication support to the client and server
          code.
        - Added Solaris options to System V commands.
        - Now support the output-bin job template attribute.
        - Now log the job-billing attribute in the page_log file, and
          keep track of the total number of pages in the
          job-media-sheets-completed attribute.
        - The penwidth option is now in micrometers to support more
          accurate width specification.
        - The image filters now support interlaced and transparent PNG
          files.
        - Didn't handle Keep-Alive for HTTP/1.0 clients.
        - The BrowsePoll support didn't handle when BrowseInterval
          was set to 0 (now uses 30 seconds if BrowseInterval is 0)
        - The DeskJet driver now supports 600 DPI color for printers
          that support it.
        - New lpinfo and lpmove commands.
        - The lpq command now supports the Digital UNIX output format.
        - The LPD mini-daemon now supports all required LPD operations.
        - Implemented timeouts for multi-file documents.
        - New cupsPrintFiles() function in the CUPS API library to
          print multiple files using create-job and send-document
          requests (1 job ID for multiple files)
        - The lp command now sends multiple files as a single job,
          matching the behavior of the System V command.
        - The "cancel -a" command now purges job history files.


CHANGES IN CUPS v1.1b3

        - Documentation updates.
        - The startup script redirected stderr before stdout,
          which caused problems with some versions of Bourne
          shell and Bash.
        - Fixed a bug in the scheduler's PPD language reading
          code.
        - Fixed a bug in the scheduler's check for the
          manufacturer in the PPD.
        - The pstoraster filter didn't allow some input and
          output attributes to be set.
        - Added banner page support.
        - Added missing PAM configuration file.
        - Configuration script fixes for Linux and *BSD.
        - The log file code was using the wrong sign for the
          timezone offset.
        - The default printcap file is now empty (no printcap
          file is generated).
        - The scheduler did not start jobs destined for remote
          printers when they became available.
        - The scheduler now sends jobs to remote printers
          immediately. (when sending jobs to a class, the remote
          printer is only used when it becomes available)
        - The scheduler now supports printing of banner pages
          via the job-sheets attribute (banner files go in
          /usr/share/cups/banners)
        - The cupsd process now forks itself into the background
          (override with -f)
        - Added several *BSD enhancements.
        - Added UNSUPPORTED libtool option to configuration
          script to allow the use of libtool.  Note that this is
          UNSUPPORTED by us, but added by request of the *BSD
          folks.
        - The parallel, serial, and usb backends now retry the
          opening of their ports.  This allows multiple print
          queues to be associated with a single physical port,
          and will allow CUPS to support several types of
          parallel port auto-switches in the near future.
        - Set-Job-Attributes now supports adding, changing, and
          deleting job template attributes, and no longer allows
          job-printer-uri to be set (see CUPS-Move-Job)
        - Added CUPS-Move-Job operation to support moving of jobs.
        - The CGI template functionality now supports multiple
          languages (still only have templates for English)
        - The CUPS-Get-Printers and CUPS-Get-Classes operations
          now support filtering as defined in the IDD.
        - The Get-Jobs, CUPS-Get-Printers, and CUPS-Get-Classes
          operations no longer limit themselves to 1000 jobs,
          printers, or classes (believe it or not, this is
          needed for some sites)
        - The web interfaces now support language-specific
          templates.
        - The web admin interface now supports class management.
        - The web admin interface now shows a list of
          manufacturers before selecting the PPD/driver for a
          specific printer.
        - The web admin interface now supports configuration of
          the default printer options in the PPD file.
        - The web interface now uses printer/class
          authentication for the test page instead of admin
          authentication.
        - Updated the RPM spec file for the current release.
        - Updated language support for Windows code pages.
        - 8-bit character set files can now use multiple fonts
          (needed for Arabic, Greek, Hebrew, etc.)
        - Added basic right-to-left text support in the text
          filter.
        - The POSIX locale now uses ISO-8859-1 instead of
          US-ASCII.
        - Fixed PDF printing problems.
        - Fixed PostScript RIP page device dictionary elements
          that weren't getting passed in cups_get_params().
        - Added a new "contains" rule for the magic file typing.
        - The "printable" rule now accepts characters from 128 to 255
          (needed for Microsoft character sets)
        - Added support for ~/.cupsrc as well as /etc/cups/client.conf
          so that the default server can be configured on a per-user
          basis without environment variables.
        - Added LPD mini-daemon to support incoming LPD jobs.


CHANGES IN CUPS v1.1b2

        - Documentation updates.
        - The lp command didn't always load the user-defined
          destinations, preventing it from seeing the default
          printer.
        - Many configure script and makefile fixes.
        - The Microsoft code page files were missing from the
          distribution.
        - Added a workaround for the HP IPP client (which is sending
          an invalid printer-uri in requests)
        - Fixed the encoding of text-with-language and name-with-language
          to match the IPP spec.
        - Added support for unknown value tags in the IPP routines
          (previously they would be ignored)
        - Integrated GNU GhostScript 5.50 into the pstoraster filter.
        - Client hostname resolution was broken on little-endian
          machines.
        - Now look at client.conf file for client's default server
          and printer.
        - The cupsServer() function did not close the client.conf file
          if it contained a ServerName directive.
        - Added BrowseAllow, BrowseDeny, BrowseOrder, BrowsePoll, and
          BrowseRelay directives.
        - BrowseInterval 0 disables advertising of local printers, but
          still receives information on remote printers.
        - New browse polling daemon (for polling servers on different
          networks)
        - New PPD cache file for faster startup times with large numbers
          of PPD files.
        - The Host: field was incorrectly required for HTTP/1.0 clients.
        - New set-job-attributes operation now supported.
        - The mime_load_types() and mime_load_convs() functions did not
          close their input files.


CHANGES IN CUPS v1.1b1

        - NEW web-based administration interface.
        - NEW EPSON printer drivers.
        - NEW user-defined printers and options.
        - NEW persistent jobs and job history
        - NEW IPP/1.1 support
        - NEW template-based web interfaces.
        - NEW CUPS-get-devices and CUPS-get-ppds operations.
        - NEW support for create-job and send-file operations.
        - NEW certificate-based authentication for local
              administration.
        - NEW USB backend.
        - The lpr command now produces human-readable error messages.
        - The lpq command now produces BSD standard format output
          instead of OSF/1 output.  This should resolve the SAMBA
          print queue problems that have been reported.
        - The IPP backend did not always detect when the "raw" option
          was being used.
        - The "lpstat -p" command would stop after the first active
          printer.
        - The "lpstat -v" command would stop before the first remote
          printer.


CHANGES IN CUPS v1.0.5

        - The HP-GL/2 filter did not correctly set the pen color
          for pens other than #1.
        - The scheduler would only accept 26 simultaneous jobs
          under some OS releases (mkstemp() limitation.)  It now
          handles up to 2^32 simultaneous jobs.
        - The PostScript filter loaded the printer's PPD file
          twice.
        - The PAM authentication code now uses pam_strerror() to
          provide a textual error message in the error_log file.
        - The scheduler now copies PPD and interface script
          files instead of moving them; this fixes installations
          with a separate requests directory.
        - The PostScript RIP did not generate correct 6-color
          output.
        - Several filters were marking PPD options twice when
          they didn't need to.
        - The scheduler did not save the printer or class state
          after an accept-jobs or reject-jobs operation.
        - The cupsGetDefault() function now ignores the PRINTER
          environment variable if it is set to "lp".
        - New ippErrorString() function to get textual error
          messages.
        - Better error reporting in the System V commands.
        - The lpadmin and lpstat commands always tried to
          connect to the default server.
        - The text filter didn't load the charset files from the
          correct location.
        - Wasn't sending a WWW-Authenticate: field to HTTP
          clients when authentication was required.
        - httpSeparate() didn't always set the default port
          number for known methods.
        - The HP-GL/2 filter now looks for "PSwidth,length"
          instead of (the correct) "PSlength,width" as
          documented by HP.  It appears that many major CAD
          applications are broken and this change allows the
          auto-rotation to work with them.
        - The IPP "printer-resolution" option was not being
          translated.
        - The charset files did not include the Microsoft
          "standard" characters from 128 to 159 (unused by the
          ISO-8859-x charsets)
        - The scheduler was chunking the Content-Type field from
          CGI programs; this problem was most noticeable with
          Microsoft Internet Explorer 5.
        - By popular demand, the printers, jobs, and classes
          CGIs no longer force a reload of the page every 10/30
          seconds.
        - The scheduler incorrectly required that the IPP client
          provide a document-format attribute for the
          validate-job operation.
        - Clients that sent bad IPP requests without the
          required attributes-natural-language and
          attributes-charset attributes would crash the
          scheduler.


CHANGES IN CUPS v1.0.4

        - Documentation updates.
        - Jobs would get stuck in the queue and wouldn't print
          until you enabled the queue.
        - The lp and lpr commands now catch SIGHUP and SIGINTR.
        - The lp and lpr commands now use sigaction or sigset
          when available.
        - CUPS library updates for WIN32/OS-2


CHANGES IN CUPS v1.0.3

        - Documentation updates.
        - The lpq man page was missing.
        - The configure script was not properly detecting the
          image libraries.
        - The top-level makefile was calling "make" instead of
          "$(MAKE)".
        - PostScript filter fixes for number-up, OutputOrder,
          and %Trailer.
        - The imagetops filter didn't end the base-85 encoding
          properly if the image data was not a multiple of 4
          bytes in length.
        - The imagetoraster filter didn't generate good banded
          RGB or CMY data (was dividing the line width by 4
          instead of 3...)
        - The imagetoraster filter now records the bounding
          box of the image on the page.
        - The CUPS image library cache code wasn't working as
          designed; images larger than the maximum RIP cache
          would eventually thrash using the same cache tile.
        - The CUPS image library TIFF loading code didn't
          handle unknown resolution units properly; the fixed
          code uses a default resolution of 128 PPI.
        - cupsGetClasses() and cupsGetPrinters() did not free
          existing strings if they ran out of memory.
        - The scheduler logs incorrectly contained 3 digits for
          the timezone offset instead of 4.
        - The scheduler now does a lookup for the default user
          and group ID; the previous hardcoded values caused
          problems with the LPD backend.
        - The cancel-job operation now allows any user in the
          system group to cancel any job.
        - The cancel-job operation stopped the print queue if
          the job was being printed.
        - Now only stop printers if the backend fails. If the
          filter fails then the failure is noted in the
          error_log and printing continues with the next file in
          the queue.
        - Now log whether a filter fails because of a signal
          or because it returned a non-zero exit status.
        - The root user now always passes the system group test.
        - Printers with an interface script and remote printers
          and classes didn't have a printer-make-and-model
          attribute.
        - Added logging of lost/timed-out remote printers.
        - The HP-GL/2 filter was scaling the pen width twice.
        - Updated the HP-GL/2 filter to use a single SP (Set
          Pen) procedure.  This makes the output smaller and is
          more appropriate since the filter keeps track of the
          pen states already.
        - The scheduler didn't handle passwords with spaces.
        - The IPP backend now does multiple copies and retries
          if the destination server requires it (e.g. HP
          JetDirect.)
        - The disable command didn't implement the "-c" option
          (cancel all jobs.)
        - Changed the CMYK generation function for the image file
          and PostScript RIPs.
        - The lp command didn't support the "-h" option as
          documented.
        - The AppSocket, IPP, and LPD backends now retry on all
          network errors.  This should prevent stopped queues
          caused by a printer being disconnected from the
          network or powered off.
        - The scheduler now restarts a job if the corresponding
          printer is modified.
        - The image RIPs now rotate the image if needed to fit
          on the page.


CHANGES IN CUPS v1.0.2

        - The HP-GL/2 filter didn't always scale the output
          correctly.
        - The HP-GL/2 filter now supports changing the page size
          automatically when the "fitplot" option is not used.
        - The cancel-job operation was expecting a resource name
          of the form "/job/#" instead of "/jobs/#"; this
          prevented the cancel and lprm commands from working.
        - The backends didn't log pages when files were printed
          using the "-oraw" option.
        - The authorization code did not work with the Slackware
          long shadow password package because its crypt() can
          return NULL.
        - The chunking code didn't work for reading the response
          of a POST request.
        - cupsGetPPD() now does authentication as needed.
        - The N-up code in the PostScript filter didn't work
          with some printers (grestoreall would restore the
          default blank page and device settings).
        - The N-up code in the PostScript filter didn't scale
          the pages to fit within the imageable area of the
          page.
        - Wasn't doing an fchown() on the request files.  This
          caused problems when the default root account group
          and CUPS group were not the same.


CHANGES IN CUPS v1.0.1

        - Documentation updates.
        - Fixed a bunch of possible buffer-overflow conditions.
        - The scheduler now supports authentication using PAM.
        - Updated the Italian message file.
        - httpEncode64() didn't add an extra "=" if there was
          only one byte in the last three-byte group.
        - Now drop any trailing character set from the locale
          string (e.g. "en_US.ISO_8859-1" becomes "en_US")
        - Fixed "timezone" vs "tm_gmtoff" usage for BSD-based
          operating systems.
        - Updated IPP security so that "get" operations can be
          done from any resource name; this allows the CGIs to
          work with printer authentication enabled so long as
          authentication isn't turned on for the whole "site".
        - The IPP code didn't properly handle the "unsupported"
          group; this caused problems with the HP JetDirect since
          it doesn't seem to support the "copies" attribute.
        - The HTTP chunking code was missing a CR LF pair at the
          end of a 0-length chunk.
        - The httpSeparate() function didn't handle embedded
          usernames and passwords in the URI properly.
        - Doing "lpadmin -p printer -E" didn't restart printing
          if there were pending jobs.
        - The cancel-job operation now requires either a
          requesting-user-name attribute or an authenticated
          username.
        - The add-printer code did not report errors if the
          interface script or PPD file could not be renamed.
        - Request files are now created without world read
          permissions.
        - Added a cupsLastError() function to the CUPS API to
          retrieve the IPP error code from the last request.
        - Options are now case-insensitive.
        - The lpq command now provides 10 characters for the
          username instead of the original (Berkeley standard)
          7.
        - The cancel command needed a local CUPS server to work
          (or the appropriate ServerName in cupsd.conf)
        - The cancel and lprm commands didn't report the IPP
          error if the job could not be cancelled.
        - The lp and lpr commands didn't intercept SIGTERM to
          remove temporary files when printing from stdin.
        - The lp and lpr commands didn't report the IPP error if
          the job could not be printed.
