   4 CHANGES IN CUPS V1.1.5
   5
   6         - Documentation updates.
   7         - Makefile/configure script updates.
   8         - The RPM spec file didn't work out-of-the-box under
   9           RedHat or Mandrake.
  10         - Minor code cleanup to remove extraneous compiler
  11           warnings.
  12         - cupsTempFile() was using %p for the temporary
  13           filename; this should have been %08x (just 8 digit
  14           hex)
  15         - Deleting a printer with active print jobs would still
  16           crash the server.
  17         - ippWrite() and ipp_write_file() didn't send the
  18           correct value length for name-with-language and
  19           text-with-language attributes.
  20         - Updated IPP code to support copied strings (that
  21           should not be freed); this provides slightly more
  22           efficient IPP server performance.
  23         - Updated PDF filter to Xpdf 0.91.
  24         - httpGets() could go into an infinite loop if a line
  25           longer than the input buffer size was sent by a
  26           client. This could be used in a Denial-of-Service
  27           attack.
  28         - The lpstat and CUPS API functions now request only the
  29           data required when getting the list of printer or
  30           class information.  This should improve performance
  31           with large numbers of printers on slower machines.
  32         - The scheduler was always enforcing the FilterLimit,
  33           even if FilterLimit was set to 0.
  34         - Updated the Linux USB backend to support Mandrake's
  35           /dev/usb/usblp# filenames.
  36         - The PRINTER and LPDEST environment variables did not
  37           override the lpoptions default printer.
  38         - The PPD read functions incorrectly included trailing
  39           characters (usually whitespace) after quoted string
  40           attributes.
  41         - The multiple-document-handling attribute handling code
  42           did not check for the correct value for collated
  43           copies (separate-documents-uncollated-copies).
  44         - The EPSON driver did not work with OKIDATA printers in
  45           EPSON emulation mode (needed change-emulation command)
  46         - The HP-GL/2 filter did not scale the plot properly in
  47           scale mode 2.
  48         - Added PPD files for 9-pin and 24-pin OKIDATA printers.
  49         - The httpSeparate() function didn't handle passwords
  50           that started with a number.
  51         - ippDelete() could free the character set string
  52           multiple times in name-with-language and
  53           text-with-language attributes.
  54         - The scheduler would access freed memory right after
  55           freeing it (for debug messages); these parts of the
  56           code have been reordered to avoid this situation
  57           which was causing sporatic errors and crashes.
  58         - The ppdClose() function didn't free all of the strings
  59           in the ppd_file_t structure.
  60         - The LoadAllJobs() function in the scheduler did not
  61           close the spool directory.
  62         - Changed all sprintf's that use string formats to
  63           snprintf's, even if the destination buffer is
  64           larger than the source string(s); this protects
  65           against buffer overflows caused outside of CUPS...
  66         - Changed all strcpy's to strncpy's between local and
  67           global variables, even if the destination buffer is
  68           larger than the source string; this protects
  69           against buffer overflows caused outside of CUPS...
  70         - The CUPS certificate functions didn't use the
  71           CUPS_SERVERROOT environment variable when set.
  72         - The directory services code was copying instead of
  73           comparing the remote printer info, resulting in
  74           unnecessary updates of the printer attributes for
  75           remote printers.
  76         - Added new mime.types rules to allow automatic raw
  77           printing of PCL and ESC/P files; PJL headers are
  78           parsed to differentiate between PostScript and
  79           PCL job files.

  82 CHANGES IN CUPS v1.1.4
  83
  84         - Makefile and configure script fixes.
  85         - **** Changed the default Printcap setting **** to
  86           /etc/printcap. There are just too many people asking
  87           why application XYZ doesn't see their printers!
  88         - The web admin interface now displays an error if it
  89           can't get the list of printer drivers from cupsd.
  90         - The IPP backend was putting the copies option before
  91           the other job options were set. This caused the IPP
  92           request to contain attribute groups in the wrong
  93           order, which prevented remote printing.
  94         - Added checks in scheduler to free memory used for
  95           IPP requests and language information when closing
  96           a client connection.
  97         - Fixed the duplex option in the HP LaserJet driver.  It
  98           should now work with all LaserJet printers (and
  99           compatibles)
 100         - The add-printer web interface didn't initialize the
 101           "old info" data pointer, which caused random crashes
 102           on many OS's.
 103         - Fixed many page sizes defined in the Level 1
 104           compatibility file "gs_statd.ps" to match reality.
 105         - Fixed another bug in the setpagedevice "code" in
 106           Ghostscript.  It should now accept all standard
 107           Adobe attributes on all platforms.
 108         - Fixed pstoraster so that it reallocates memory for
 109           color depth changes as well as size/resolution
 110           changes.  This removes an ordering constraint on
 111           the color, page size, and resolution options in
 112           PPD files.
 113         - The IPP backend didn't use the job's character set
 114           when the destination printer supported it.  This
 115           caused problems when printing text files to other
 116           CUPS servers.
 117         - Updated the logic used to determine when to rebuild
 118           the PPD file database.  The scheduler now checks the
 119           dates and the number of PPD files (was just checking
 120           the dates.)
 121         - Updated the ippSetCGIVars() function (used by the
 122           web interfaces) to only filter valid string values.
 123         - The PostScript filter was scaling 2-up pages
 124           incorrectly.  This caused the edges of some pages to
 125           be clipped.
 126
 127
 128 CHANGES IN CUPS v1.1.3
 129
 130         - Makefile fixes.
 131         - RPM spec file changes.
 132         - Documentation updates.
 133         - Enabled pstoraster debug messages for everything
 134           (only logged when LogLevel set to "debug"...)
 135         - Changed the Input/OutputAttributes fix in
 136           pstoraster so that it works on all platforms.
 137         - The HP-GL/2 filter didn't set the right green
 138           color value in encoded polylines or text.
 139         - Updated the "fitplot" code to handle plot sizes
 140           specified as "PSwidth,length" and "PSlength,width".
 141         - Updated the Linux parallel and USB backends to open
 142           the device files prior to looking in /proc for
 143           autoprobe info. This makes sure that loadable device
 144           driver modules are in fact loaded...
 145         - Added new FilterLimit directive to limit the number
 146           of processing jobs/filters on a system.
 147         - set-job-attributes didn't change the job-state to
 148           held/pending when the job-hold-until attribute was
 149           specified.
 150         - set-job-attributes didn't save the new job attributes.
 151         - Now change the "requesting-user-name" attribute in
 152           requests from remote systems to "remroot" when an
 153           unauthenticated "root" user is sent. This can be
 154           changed using the new RemoteRoot directive in
 155           cupsd.conf.
 156         - The cancel-job, hold-job, release-job, and restart-job
 157           operations didn't log the authenticated username.
 158         - The cups-lpd mini-daemon now checks for a
 159           document-format option before forcing raw mode with
 160           filter mode 'l'.
 161         - The cups-lpd mini-daemon now supports "-o" options
 162           on the command-line (passed by inetd) to set global
 163           defaults for all print queues.
 164         - The pstops filter assumed that a file with a Trailer
 165           comment would also have an EOF comment.
 166         - Added new cupsSetPasswordCB(), cupsSetServer(),
 167           cupsSetUser(), and ippSetPort() functions to better
 168           support client applications (especially GUIs...)
 169         - The CUPS-add-class and CUPS-add-printer operations
 170           didn't reset the printer-name attribute on remote
 171           print queues that had to be renamed when a local
 172           printer was defined with the same name.
 173         - The lpoptions command now supports a "-r" option to
 174           remove options for a printer or instance.
 175         - The lpadmin and admin.cgi programs no longer allow
 176           class and printer names to begin with a number; this
 177           caused the command-line utilities to become confused.
 178         - The Linux USB backend now looks for both the parallel
 179           and usblp driver names in the device list.
 180         - Added a new FontPath directive to cupsd.conf, and also
 181           a "--with-fontpath" option for the configure script to
 182           specify alternate font paths for pstoraster.
 183         - The CUPS-move-job operation didn't update the
 184           job-printer-uri attribute.
 185         - The scheduler only looked up printers and classes by
 186           name in IPP requests, instead of using the full URI.
 187           This caused problems with KUPS and friends with
 188           remote printers.
 189         - The scheduler now handles better localization of
 190           hostnames (e.g. server is host.foo.com, remote is
 191           host.subfoo.foo.com, localized is not host.subfoo...)
 192         - The scheduler logging functions now use a common
 193           log file checking/rotation function (courtesy of
 194           Crutcher Dunnavant at Red Hat)
 195         - The scheduler could accept more client connections
 196           than it allocated for if more than one Port or Listen
 197           line was present in cupsd.conf.
 198         - Other minor scheduler performance tweeks.
 199         - The lpq and lprm commands didn't support the default
 200           printer set using lpoptions.
 201         - The lpoptions command now supports a "-l" option to
 202           list the printer-specific options and their current
 203           settings.
 204         - The web printer and class lists now show a link to the
 205           default printer or class at the top of the page.
 206         - The text filter now supports pretty printing of shell
 207           and perl scripts as well as C/C++ source files.
 208         - The top and bottom margins were reversed for landscape
 209           text printing.
 210         - The lpq and lprm commands didn't understand printer
 211           instances.
 212         - The scheduler only selected on the first 100 file
 213           descriptors instead of the maximum file descriptor
 214           limit.
 215         - The scheduler client, listener, and mainline functions
 216           now share code to disable and enable monitoring for
 217           new client connections.
 218         - The imagetoraster filter didn't support all of the
 219           required pagedevice parameters.
 220         - The serial backend now checks for 100 serial ports
 221           under Linux.
 222         - The scheduler used sscanf() to pull out the remote
 223           printer location, description, and make/model strings,
 224           but if any of these options was empty then sscanf()
 225           would stop processing.
 226         - Added "debug2" log level to provide a little less
 227           verbose debugging information at the "debug" level.
 228         - The scheduler would crash if you stopped a printer
 229           that was currently printing a job.
 230         - The scheduler incorrectly allowed jobs in the cancelled,
 231           aborted, or completed state to be cancelled.
 232         - The image filters did not load TIFF images properly
 233           for bottom-to-top and right-to-left orientations.
 234         - Added new cupsEncodeOptions() function to encode
 235           CUPS options as IPP job attributes.
 236         - The IPP backend, LPD mini-daemon, client commands,
 237           and CUPS API did not properly encode multiple
 238           option values separated by commas.
 239         - Added new scheduler malloc logging in debug mode
 240           (provides summary of total arena size, allocated,
 241            and free bytes once a minute)
 242         - The EPM-based distributions didn't install the
 243           correct symlinks for a few man pages.
 244         - Fixed a memory leak in the scheduler - wasn't
 245           freeing old filters when deleting or renaming
 246           printers.
 247         - The scheduler now queries the primary IP address
 248           for the name of the server and maps any incoming
 249           requests from that address to the server name.
 250           This fixes web admin mapping problems from
 251           server.domain.com to localhost.
 252         - The web printer modify interface now remembers
 253           the previous device and driver settings (except
 254           for serial ports.)
 255         - The job-k-octets attribute is now stored as part of
 256           the job attributes; this preserves the information
 257           after a job is completed when job file history is
 258           turned off.
 259         - Dropped option sub-group parsing code for the moment,
 260           since many Xerox PPD files abuse this feature in PPD
 261           files and don't follow the hierarchy rules.
 262         - Added new wrapper code around options so that duplex
 263           options for some HP printers don't prevent prints.
 264         - Added support for Digital UNIX/Tru64 UNIX/OSF/1 format
 265           for "lpstat -v" output.
 266         - Now show the URI for remote printers instead of
 267           /dev/null in "lpstat -v" output.
 268         - Creating classes and adding printers to a class with
 269           the lpadmin command didn't work.
 270         - The banner pages and test page should now format
 271           correctly in both portrait and landscape orientations.
 272         - Updated banner page substitution so that { can appear
 273           by itself without quoting.
 274
 275
 276 CHANGES IN CUPS v1.1.2
 277
 278         - Makefile/configure fixes
 279         - RPM spec file and EPM list file fixes
 280         - The cupsTempFile() function now uses a different
 281           algorithm for generating temp files and "reserves"
 282           them to avoid possible security exploitation.
 283         - Now use /dev/random (if available) to seed the random
 284           number generator for certificates.
 285         - The /var/spool/cups and /var/spool/cups/tmp directories
 286           were incorrectly owned by root; they are now owned by
 287           the filter user, typically "lp".
 288         - The scheduler now resets the permissions on the spool
 289           and temp directories as needed to match the filter
 290           user.
 291         - Now expose ppdCollect() as an externally callable
 292           function.
 293         - The image filters now support filtering from the
 294           standard input.
 295         - The imagetoraster filter now collects all printer
 296           options and job patch files and applies them to the
 297           page header as needed.
 298         - Added format and banner options to LPD backend.
 299         - The send-document operation didn't start a job
 300           immediately when last-document was true.
 301         - The set-job-attributes operation didn't correctly
 302           replace the current job-hold-until value.
 303         - Removed the option wrapper code from ppdEmit() and
 304           friends since it caused problems with Ghostscript
 305           and many PS printers.
 306         - Was setting TZ environment variable twice for job
 307           filters.
 308         - Added syslog logging in cups-lpd to aide in
 309           debugging problems.
 310         - The HP-UX parallel port backend did not list the
 311           available parallel ports on some systems (printf
 312           calling problem...)
 313         - The lp and lpr commands overrode user options if
 314           -d/-P were specified after -o.
 315         - The scheduler would crash with a */* filter.
 316         - Added support for a "default" filter for unknown file
 317           types.  The example provided in the mime.types and
 318           mime.convs file prints unknown files as if "-oraw" was
 319           specified for the job.  This functionality is disabled
 320           by default.
 321         - The "compatibility" mode fix for older backends did not
 322           work for smbspool.  Added a workaround for it.
 323         - The HP-GL/2 filter didn't perform the right pen scaling
 324           with some files and the "fitplot" option.
 325         - New Software Performance Specification document that
 326           describes the memory, disk, and CPU usage of all the
 327           CUPS software.
 328
 329
 330 CHANGES IN CUPS v1.1.1
 331
 332         - The pstoraster Makefile still referenced one of the
 333           old PDF filter files.
 334         - The filter Makefile used INSTALL_DATA instead of
 335           INSTALL_LIB to install the CUPS image library.
 336         - The administration CGI didn't work properly with
 337           network devices.
 338         - The BrowseACL variable was not updated after the
 339           cupsd.conf file was loaded.
 340         - The lpd mini-daemon didn't support printer instances.
 341         - Now use a default umask of 077 for child processes.
 342         - Now put temp files in /var/spool/cups/tmp for child
 343           processes and the root user, unless TMPDIR or TempDir
 344           is defined otherwise.
 345         - cupsGetPPD() no longer uses easy-to-guess filenames.
 346         - The CUPS-Delete-Class and CUPS-Delete-Printer
 347           operations now save classes.conf file as needed.
 348         - The lppasswd command wouldn't add a user.
 349         - The ppdOpen() function could cause a segfault if a
 350           0-length PPD file was read.
 351         - The image filters were not handling images with
 352           different X and Y resolutions properly.
 353         - The imagetoraster filter defaulted to RGB output
 354           instead of black output like pstoraster.
 355         - The pstops filter didn't handle binary data properly.
 356         - The pstops filter didn't handle copies properly for
 357           PS files lacking DSC comments.
 358         - The pstops filter now appends %%EOF to the end of
 359           documents if they don't have it.
 360         - The cupsGetPPD() function didn't work with remote
 361           printers lacking the @server in the name.
 362         - The configure script didn't work right when only
 363           --prefix was specified.
 364         - The ppdEmit() code now wraps all printer commands so
 365           that buggy PostScript printers will still print a file
 366           after receiving an option that isn't available.
 367         - Fixed the DeskJet margin bug, and disabled 600dpi
 368           color mode until it can be fixed.
 369         - The cupsAddDest() function didn't sort instances
 370           correctly in all cases.
 371         - The time-at-xyz attributes now expand to the date and
 372           time in banner files.
 373
 374
 375 CHANGES IN CUPS v1.1
 376
 377         - Documentation updates.
 378         - Configuration script updates.
 379         - Didn't map charset and language value strings to lowercase
 380           and _ to - as required by SLP and IPP.
 381         - ppdLoadXYZ() didn't add the list of available fonts to the
 382           ppd_file_t structure.
 383         - The text filter common code was freeing the PPD file data
 384           before it was used.
 385         - The text filter now embeds missing fonts.
 386         - The CGI interface now maps local access to the server to
 387           the localhost address.
 388         - The HP-GL/2 filter didn't use the specified (or default)
 389           color ranges, resulting in strange colors.
 390         - The HP-GL/2 filter didn't default to no input window, which
 391           caused unnecessary clipping of plots.
 392         - Integrated Xpdf's pdftops filter into CUPS, which is a
 393           lightweight and reliable replacement for Ghostscript's
 394           PDF support.
 395         - Removed all PDF support from Ghostscript.
 396         - Updated HP driver to set top margin; this seems to fix
 397           the offset problem seen on HP DeskJet printers.
 398         - Fixed dependencies on the ZLIB and JPEG libraries in
 399           pstoraster.
 400         - The lpr command wasn't using the lpoptions defined by
 401           the user.
 402         - The lpr command would segfault if the CUPS server was
 403           not running.
 404         - The top-level makefile was not installing the CUPS
 405           initialization script.  It now does so if it sees there
 406           is an init.d directory in /sbin, /etc/rc.d, or /etc.
 407         - "lpstat -v all" didn't work.
 408         - pstoraster would crash on some platforms doing the
 409           setpagedevice operator.
 410         - The web administration interface now allows you to set
 411           the default banner pages.
 412         - Images can now be positioned on the page using the new
 413           "position" option.
 414         - The AccessLog, ErrorLog, and PageLog directives now
 415           support "%s" to insert the server name.
 416         - Added a new BrowseShortNames directive to allow for
 417           short remote printer names ("printer" instead of
 418           "printer@server") when possible.
 419         - The scheduler could crash if given an invalid PPD file
 420           with no PageSize attributes.
 421         - Updated the serial, parallel, and usb backends to do
 422           multiple writes and ignore ioctl() errors as needed;
 423           this should fix problems with serial printing on old
 424           serial drivers and with the UltraSPARC parallel port
 425           driver under Solaris 2.7.
 426         - Now propagate LD_LIBRARY_PATH to child processes from
 427           cupsd.
 428         - New DataDir directive for installing in alternate
 429           locations.
 430         - New CUPS_SERVERROOT and CUPS_DATADIR environment
 431           variables to specify installation directories as
 432           needed.
 433         - Queued remote jobs recreate remote printers as needed
 434           when the scheduler is started.
 435         - Deleting a printer also purges all jobs on that
 436           printer.
 437         - Old job and control files that don't belong to a
 438           printer are automatically deleted.
 439         - Wasn't updating time-at-processing and
 440           time-at-completed attributes in job.
 441         - Didn't send required multiple-operation-time-out
 442           attribute in response to a get-printer-attributes
 443           request.
 444         - cups-lpd now supports options set with lpoptions.
 445         - The job-hold-until attribute is now provided with all
 446           jobs. For jobs that are not currently held the value
 447           is "no-hold".
 448         - The scheduler was not sending "unknown" values in IPP
 449           responses.
 450         - The lpoptions command now accumulates options from
 451           previous runs rather than replacing all options for a
 452           printer.
 453         - The IPP backend now switches to IPP/1.0 if a 1.1
 454           request fails.
 455         - The lpadmin and admin.cgi programs now validate new
 456           printer and class names.
 457         - The access_log file now includes the number of IPP bytes
 458           received in a POST request.
 459
 460
 461 CHANGES IN CUPS v1.1b5
 462
 463         - Documentation updates.
 464         - The pstoraster filter didn't compile without the JPEG library.
 465         - The cupsd server didn't support the HTTP OPTIONS request
 466           method.
 467         - Dropped the "CLOSE" method supported by the cupsd server.
 468           (not defined in HTTP specification)
 469         - Makefile/configure script fixes.
 470         - Missing the job-restart template.
 471         - Added IPP test suite for testing.
 472         - Missing IPP documentation from binary distributions.
 473         - Fixed multiple-document handling code when last-document
 474           not specified.
 475         - Added more checks to IPP requests to prevent bad requests
 476           from getting through.
 477         - Not all of the Ghostscript error output was being sent to
 478           stderr.
 479         - The PostScript filter now added PJL commands to set the
 480           job name and display string, if supported.
 481         - The scheduler would crash if the browse socket could not
 482           be bound. Now disables browsing if port 631 (reserved for
 483           IPP) is being used by a misbehaving daemon.
 484         - The USB backend now looks for the older Linux 2.2.x USB
 485           printer device filenames as well as the newer ones.
 486         - The IPP backend now uses the UTF-8 charset exclusively,
 487           since apparently only CUPS handles more than US-ASCII and
 488           UTF-8...
 489         - Wasn't quoting ( in PostScript banners...
 490         - Send-document requests with no document-format attribute
 491           could cause cupsd to crash.
 492         - Old jobs in the spool directory might cause cupsd to
 493           crash.
 494         - CUPS now supports all of the recommended job-hold-until
 495           keywords as well as name values of the form "HH:MM" and
 496           "HH:MM:SS".
 497         - Added placeholder pointer for TLS encryption to the HTTP
 498           connection structure.
 499         - Fixed the "fast poll" bug reported by DISA - the
 500           status pipe wasn't being closed for multi-file jobs.
 501         - Revamped put_params code in pstoraster to fix bitmap
 502           allocation bug with FrameMaker output.
 503         - Ripped out filename, etc. code from pstoraster as it
 504           is a potential security hole.
 505         - Added support for RIP_CACHE environment variable in the
 506           new pstoraster.
 507         - Fixed USB device filenames for Linux; now support new
 508           pre-2.4 devices (/dev/usb/lp#) and 2.2 devices
 509           (/dev/usblp#)
 510         - Fixed accept-jobs crash with classes.
 511         - Didn't include dot-matrix EPSON drivers in previous
 512           release.
 513
 514
 515 CHANGES IN CUPS v1.1b4
 516
 517         - Documentation updates.
 518         - Many makefile and configuration script fixes (should
 519           now compile better under *BSD.)
 520         - The MediaPosition attribute was being mishandled by
 521           GhostScript, causing the RIP to fail whenever a paper
 522           tray was selected.
 523         - The scheduler now logs the final line of log information
 524           from a filter, even if it doesn't end with a newline; this
 525           primarily affects GhostScript error output.
 526         - The scheduler was saving implicit classes, so after a few
 527           restarts you'll end up with AnyPrinter, AnyAnyPrinter, etc.
 528         - The JPEG autodetection didn't work with some JPEG files that
 529           came from digital cameras (JPEG but not JFIF); the new
 530           magic types should work with all images that the JPEG library
 531           can handle.
 532         - Fixed a bug in the new contains() MIME type rule that could
 533           cause cupsd to crash.
 534         - Switched to using strtol() in the MIME type code so that you
 535           can use hex, octal, or decimal constants as desired in the
 536           mime.types file.
 537         - Banner files are now treated as templates, allowing any type
 538           of file to be used as a banner.
 539         - Added a 30-second timeout to backend device reports so that a
 540           hung backend will not prevent the scheduler from starting.
 541         - Backends are once again terminated when jobs are stopped; the
 542           CUPS-supplied backends will stay alive until the downstream
 543           filters have had a chance to clear out old page data.
 544         - The charset lookup in the CUPS localization support was wrong
 545           (iso8859-x instead of iso-8859-x)
 546         - Changed the "cpNNNN" code page files to "windows-NNNN" to match
 547           the IANA registrations.
 548         - New PostScript banner pages.
 549         - Added Windows BMP and Alias PIX image file support to the image
 550           filter.
 551         - The PNG reading coded didn't free all of its buffers.
 552         - Added Digest authentication support to the client and server
 553           code.
 554         - Added Solaris options to System V commands.
 555         - Now support the output-bin job template attribute.
 556         - Now log the job-billing attribute in the page_log file, and
 557           keep track of the total number of pages in the
 558           job-media-sheets-completed attribute.
 559         - The penwidth option is now in micrometers to support more
 560           accurate width specification.
 561         - The image filters now support interlaced and transparent PNG
 562           files.
 563         - Didn't handle Keep-Alive for HTTP/1.0 clients.
 564         - The BrowsePoll support didn't handle when BrowseInterval
 565           was set to 0 (now uses 30 seconds if BrowseInterval is 0)
 566         - The DeskJet driver now supports 600 DPI color for printers
 567           that support it.
 568         - New lpinfo and lpmove commands.
 569         - The lpq command now supports the Digital UNIX output format.
 570         - The LPD mini-daemon now supports all required LPD operations.
 571         - Implemented timeouts for multi-file documents.
 572         - New cupsPrintFiles() function in the CUPS API library to
 573           print multiple files using create-job and send-document
 574           requests (1 job ID for multiple files)
 575         - The lp command now sends multiple files as a single job,
 576           matching the behavior of the System V command.
 577         - The "cancel -a" command now purges job history files.
 578
 579
 580 CHANGES IN CUPS v1.1b3
 581
 582         - Documentation updates.
 583         - The startup script redirected stderr before stdout,
 584           which caused problems with some versions of Bourne
 585           shell and Bash.
 586         - Fixed a bug in the scheduler's PPD language reading
 587           code.
 588         - Fixed a bug in the scheduler's check for the
 589           manufacturer in the PPD.
 590         - The pstoraster filter didn't allow some input and
 591           output attributes to be set.
 592         - Added banner page support.
 593         - Added missing PAM configuration file.
 594         - Configuration script fixes for Linux and *BSD.
 595         - The log file code was using the wrong sign for the
 596           timezone offset.
 597         - The default printcap file is now empty (no printcap
 598           file is generated).
 599         - The scheduler did not start jobs destined for remote
 600           printers when they became available.
 601         - The scheduler now sends jobs to remote printers
 602           immediately. (when sending jobs to a class, the remote
 603           printer is only used when it becomes available)
 604         - The scheduler now supports printing of banner pages
 605           via the job-sheets attribute (banner files go in
 606           /usr/share/cups/banners)
 607         - The cupsd process now forks itself into the background
 608           (override with -f)
 609         - Added several *BSD enhancements.
 610         - Added UNSUPPORTED libtool option to configuration
 611           script to allow the use of libtool.  Note that this is
 612           UNSUPPORTED by us, but added by request of the *BSD
 613           folks.
 614         - The parallel, serial, and usb backends now retry the
 615           opening of their ports.  This allows multiple print
 616           queues to be associated with a single physical port,
 617           and will allow CUPS to support several types of
 618           parallel port auto-switches in the near future.
 619         - Set-Job-Attributes now supports adding, changing, and
 620           deleting job template attributes, and no longer allows
 621           job-printer-uri to be set (see CUPS-Move-Job)
 622         - Added CUPS-Move-Job operation to support moving of jobs.
 623         - The CGI template functionality now supports multiple
 624           languages (still only have templates for English)
 625         - The CUPS-Get-Printers and CUPS-Get-Classes operations
 626           now support filtering as defined in the IDD.
 627         - The Get-Jobs, CUPS-Get-Printers, and CUPS-Get-Classes
 628           operations no longer limit themselves to 1000 jobs,
 629           printers, or classes (believe it or not, this is
 630           needed for some sites)
 631         - The web interfaces now support language-specific
 632           templates.
 633         - The web admin interface now supports class management.
 634         - The web admin interface now shows a list of
 635           manufacturers before selecting the PPD/driver for a
 636           specific printer.
 637         - The web admin interface now supports configuration of
 638           the default printer options in the PPD file.
 639         - The web interface now uses printer/class
 640           authentication for the test page instead of admin
 641           authentication.
 642         - Updated the RPM spec file for the current release.
 643         - Updated language support for Windows code pages.
 644         - 8-bit character set files can now use multiple fonts
 645           (needed for Arabic, Greek, Hebrew, etc.)
 646         - Added basic right-to-left text support in the text
 647           filter.
 648         - The POSIX locale now uses ISO-8859-1 instead of
 649           US-ASCII.
 650         - Fixed PDF printing problems.
 651         - Fixed PostScript RIP page device dictionary elements
 652           that weren't getting passed in cups_get_params().
 653         - Added a new "contains" rule for the magic file typing.
 654         - The "printable" rule now accepts characters from 128 to 255
 655           (needed for Microsoft character sets)
 656         - Added support for ~/.cupsrc as well as /etc/cups/client.conf
 657           so that the default server can be configured on a per-user
 658           basis without environment variables.
 659         - Added LPD mini-daemon to support incoming LPD jobs.
 660
 661
 662 CHANGES IN CUPS v1.1b2
 663
 664         - Documentation updates.
 665         - The lp command didn't always load the user-defined
 666           destinations, preventing it from seeing the default
 667           printer.
 668         - Many configure script and makefile fixes.
 669         - The Microsoft code page files were missing from the
 670           distribution.
 671         - Added a workaround for the HP IPP client (which is sending
 672           an invalid printer-uri in requests)
 673         - Fixed the encoding of text-with-language and name-with-language
 674           to match the IPP spec.
 675         - Added support for unknown value tags in the IPP routines
 676           (previously they would be ignored)
 677         - Integrated GNU GhostScript 5.50 into the pstoraster filter.
 678         - Client hostname resolution was broken on little-endian
 679           machines.
 680         - Now look at client.conf file for client's default server
 681           and printer.
 682         - The cupsServer() function did not close the client.conf file
 683           if it contained a ServerName directive.
 684         - Added BrowseAllow, BrowseDeny, BrowseOrder, BrowsePoll, and
 685           BrowseRelay directives.
 686         - BrowseInterval 0 disables advertising of local printers, but
 687           still receives information on remote printers.
 688         - New browse polling daemon (for polling servers on different
 689           networks)
 690         - New PPD cache file for faster startup times with large numbers
 691           of PPD files.
 692         - The Host: field was incorrectly required for HTTP/1.0 clients.
 693         - New set-job-attributes operation now supported.
 694         - The mime_load_types() and mime_load_convs() functions did not
 695           close their input files.
 696

 698 CHANGES IN CUPS v1.1b1
 699
 700         - NEW web-based administration interface.
 701         - NEW EPSON printer drivers.
 702         - NEW user-defined printers and options.
 703         - NEW persistent jobs and job history
 704         - NEW IPP/1.1 support
 705         - NEW template-based web interfaces.
 706         - NEW CUPS-get-devices and CUPS-get-ppds operations.
 707         - NEW support for create-job and send-file operations.
 708         - NEW certificate-based authentication for local
 709               administration.
 710         - NEW USB backend.
 711         - The lpr command now produces human-readable error messages.
 712         - The lpq command now produces BSD standard format output
 713           instead of OSF/1 output.  This should resolve the SAMBA
 714           print queue problems that have been reported.
 715         - The IPP backend did not always detect when the "raw" option
 716           was being used.
 717         - The "lpstat -p" command would stop after the first active
 718           printer.
 719         - The "lpstat -v" command would stop before the first remote
 720           printer.
 721
 722
 723 CHANGES IN CUPS v1.0.5
 724
 725         - The HP-GL/2 filter did not correctly set the pen color
 726           for pens other than #1.
 727         - The scheduler would only accept 26 simultaneous jobs
 728           under some OS releases (mkstemp() limitation.)  It now
 729           handles up to 2^32 simultaneous jobs.
 730         - The PostScript filter loaded the printer's PPD file
 731           twice.
 732         - The PAM authentication code now uses pam_strerror() to
 733           provide a textual error message in the error_log file.
 734         - The scheduler now copies PPD and interface script
 735           files instead of moving them; this fixes installations
 736           with a separate requests directory.
 737         - The PostScript RIP did not generate correct 6-color
 738           output.
 739         - Several filters were marking PPD options twice when
 740           they didn't need to.
 741         - The scheduler did not save the printer or class state
 742           after an accept-jobs or reject-jobs operation.
 743         - The cupsGetDefault() function now ignores the PRINTER
 744           environment variable if it is set to "lp".
 745         - New ippErrorString() function to get textual error
 746           messages.
 747         - Better error reporting in the System V commands.
 748         - The lpadmin and lpstat commands always tried to
 749           connect to the default server.
 750         - The text filter didn't load the charset files from the
 751           correct location.
 752         - Wasn't sending a WWW-Authenticate: field to HTTP
 753           clients when authentication was required.
 754         - httpSeparate() didn't always set the default port
 755           number for known methods.
 756         - The HP-GL/2 filter now looks for "PSwidth,length"
 757           instead of (the correct) "PSlength,width" as
 758           documented by HP.  It appears that many major CAD
 759           applications are broken and this change allows the
 760           auto-rotation to work with them.
 761         - The IPP "printer-resolution" option was not being
 762           translated.
 763         - The charset files did not include the Microsoft
 764           "standard" characters from 128 to 159 (unused by the
 765           ISO-8859-x charsets)
 766         - The scheduler was chunking the Content-Type field from
 767           CGI programs; this problem was most noticeable with
 768           Microsoft Internet Explorer 5.
 769         - By popular demand, the printers, jobs, and classes
 770           CGIs no longer force a reload of the page every 10/30
 771           seconds.
 772         - The scheduler incorrectly required that the IPP client
 773           provide a document-format attribute for the
 774           validate-job operation.
 775         - Clients that sent bad IPP requests without the
 776           required attributes-natural-language and
 777           attributes-charset attributes would crash the
 778           scheduler.
 779
 780
 781 CHANGES IN CUPS v1.0.4
 782
 783         - Documentation updates.
 784         - Jobs would get stuck in the queue and wouldn't print
 785           until you enabled the queue.
 786         - The lp and lpr commands now catch SIGHUP and SIGINTR.
 787         - The lp and lpr commands now use sigaction or sigset
 788           when available.
 789         - CUPS library updates for WIN32/OS-2
 790
 791
 792 CHANGES IN CUPS v1.0.3
 793
 794         - Documentation updates.
 795         - The lpq man page was missing.
 796         - The configure script was not properly detecting the
 797           image libraries.
 798         - The top-level makefile was calling "make" instead of
 799           "$(MAKE)".
 800         - PostScript filter fixes for number-up, OutputOrder,
 801           and %Trailer.
 802         - The imagetops filter didn't end the base-85 encoding
 803           properly if the image data was not a multiple of 4
 804           bytes in length.
 805         - The imagetoraster filter didn't generate good banded
 806           RGB or CMY data (was dividing the line width by 4
 807           instead of 3...)
 808         - The imagetoraster filter now records the bounding
 809           box of the image on the page.
 810         - The CUPS image library cache code wasn't working as
 811           designed; images larger than the maximum RIP cache
 812           would eventually thrash using the same cache tile.
 813         - The CUPS image library TIFF loading code didn't
 814           handle unknown resolution units properly; the fixed
 815           code uses a default resolution of 128 PPI.
 816         - cupsGetClasses() and cupsGetPrinters() did not free
 817           existing strings if they ran out of memory.
 818         - The scheduler logs incorrectly contained 3 digits for
 819           the timezone offset instead of 4.
 820         - The scheduler now does a lookup for the default user
 821           and group ID; the previous hardcoded values caused
 822           problems with the LPD backend.
 823         - The cancel-job operation now allows any user in the
 824           system group to cancel any job.
 825         - The cancel-job operation stopped the print queue if
 826           the job was being printed.
 827         - Now only stop printers if the backend fails. If the
 828           filter fails then the failure is noted in the
 829           error_log and printing continues with the next file in
 830           the queue.
 831         - Now log whether a filter fails because of a signal
 832           or because it returned a non-zero exit status.
 833         - The root user now always passes the system group test.
 834         - Printers with an interface script and remote printers
 835           and classes didn't have a printer-make-and-model
 836           attribute.
 837         - Added logging of lost/timed-out remote printers.
 838         - The HP-GL/2 filter was scaling the pen width twice.
 839         - Updated the HP-GL/2 filter to use a single SP (Set
 840           Pen) procedure.  This makes the output smaller and is
 841           more appropriate since the filter keeps track of the
 842           pen states already.
 843         - The scheduler didn't handle passwords with spaces.
 844         - The IPP backend now does multiple copies and retries
 845           if the destination server requires it (e.g. HP
 846           JetDirect.)
 847         - The disable command didn't implement the "-c" option
 848           (cancel all jobs.)
 849         - Changed the CMYK generation function for the image file
 850           and PostScript RIPs.
 851         - The lp command didn't support the "-h" option as
 852           documented.
 853         - The AppSocket, IPP, and LPD backends now retry on all
 854           network errors.  This should prevent stopped queues
 855           caused by a printer being disconnected from the
 856           network or powered off.
 857         - The scheduler now restarts a job if the corresponding
 858           printer is modified.
 859         - The image RIPs now rotate the image if needed to fit
 860           on the page.
 861
 862
 863 CHANGES IN CUPS v1.0.2
 864
 865         - The HP-GL/2 filter didn't always scale the output
 866           correctly.
 867         - The HP-GL/2 filter now supports changing the page size
 868           automatically when the "fitplot" option is not used.
 869         - The cancel-job operation was expecting a resource name
 870           of the form "/job/#" instead of "/jobs/#"; this
 871           prevented the cancel and lprm commands from working.
 872         - The backends didn't log pages when files were printed
 873           using the "-oraw" option.
 874         - The authorization code did not work with the Slackware
 875           long shadow password package because its crypt() can
 876           return NULL.
 877         - The chunking code didn't work for reading the response
 878           of a POST request.
 879         - cupsGetPPD() now does authentication as needed.
 880         - The N-up code in the PostScript filter didn't work
 881           with some printers (grestoreall would restore the
 882           default blank page and device settings).
 883         - The N-up code in the PostScript filter didn't scale
 884           the pages to fit within the imageable area of the
 885           page.
 886         - Wasn't doing an fchown() on the request files.  This
 887           caused problems when the default root account group
 888           and CUPS group were not the same.
 889
 890
 891 CHANGES IN CUPS v1.0.1
 892
 893         - Documentation updates.
 894         - Fixed a bunch of possible buffer-overflow conditions.
 895         - The scheduler now supports authentication using PAM.
 896         - Updated the Italian message file.
 897         - httpEncode64() didn't add an extra "=" if there was
 898           only one byte in the last three-byte group.
 899         - Now drop any trailing character set from the locale
 900           string (e.g. "en_US.ISO_8859-1" becomes "en_US")
 901         - Fixed "timezone" vs "tm_gmtoff" usage for BSD-based
 902           operating systems.
 903         - Updated IPP security so that "get" operations can be
 904           done from any resource name; this allows the CGIs to
 905           work with printer authentication enabled so long as
 906           authentication isn't turned on for the whole "site".
 907         - The IPP code didn't properly handle the "unsupported"
 908           group; this caused problems with the HP JetDirect since
 909           it doesn't seem to support the "copies" attribute.
 910         - The HTTP chunking code was missing a CR LF pair at the
 911           end of a 0-length chunk.
 912         - The httpSeparate() function didn't handle embedded
 913           usernames and passwords in the URI properly.
 914         - Doing "lpadmin -p printer -E" didn't restart printing
 915           if there were pending jobs.
 916         - The cancel-job operation now requires either a
 917           requesting-user-name attribute or an authenticated
 918           username.
 919         - The add-printer code did not report errors if the
 920           interface script or PPD file could not be renamed.
 921         - Request files are now created without world read
 922           permissions.
 923         - Added a cupsLastError() function to the CUPS API to
 924           retrieve the IPP error code from the last request.
 925         - Options are now case-insensitive.
 926         - The lpq command now provides 10 characters for the
 927           username instead of the original (Berkeley standard)
 928           7.
 929         - The cancel command needed a local CUPS server to work
 930           (or the appropriate ServerName in cupsd.conf)
 931         - The cancel and lprm commands didn't report the IPP
 932           error if the job could not be cancelled.
 933         - The lp and lpr commands didn't intercept SIGTERM to
 934           remove temporary files when printing from stdin.
 935         - The lp and lpr commands didn't report the IPP error if
 936           the job could not be printed.
