          to another queue (STR #56)

          ServerRoot directory (STR #1324)
        - The rastertodymo driver has been renamed to
          rastertolabel (a symlink is installed so that existing
          queues continue to work) and now also supports Zebra's
          CPCL language.

          comments section (STR #539, STR #830)
        - Added a new cups_array_t and cupsArray*() functions to

          a class - this allows the next printer in the class to
          print the job (STR #1084)
        - The scheduler now verifies that a printer supports
          Letter or A4 media sizes before setting them as the

          is disconnected or turned off (STR #1267)
        - Added new httpGetHostname() function to CUPS API, and
          use it instead of gethostname() so that the web

          is not the FQDN (STR #1266)
        - The scheduler now stops printers if the backend for the
          queue is missing on startup (STR #1265)
        - The configure script now supports "--disable-library"

          libraries, even if they are available on the build
          system (STR #1248)
        - The IPP backend did not always report on the total
          number of pages that were printed (STR #1251)

        - The cupstestppd program would segfault when testing
          certain broken PPD files (STR #1268)
        - Dramatically reduced the overhead of implicit classes.
        - Added new cupsDir*() functions to CUPS API.
        - Printers can now be published individually for sharing.
        - Fixed a bug in the scheduler's startup signalling code
          which caused cupsd to send the SIGUSR1 signal to the
          init process instead of the original parent process
          (STR #1258)
        - Added new on-line help CGI to web interface to provide
          searchable help.
        - Devices are now tracked dynamically, with each query
          doing a new device scan.  This eliminates a previous
          startup delay caused by slow backends and allows new
          printers to be seen without restarting the server,
          however it limits the amount of device URI checking
          that can be done (basically now the scheduler only
          requires a URI with a method that is a listed backend)
        - Added new printer auto-detection, server configuration,
          and log file viewing to the administration web page.
        - Added new "set allowed users" web interface to set the
          list of allowed users for a printer or class.
        - The scheduler, command-line, and web interfaces now
          limit the list of printers and classes to those
          accessible by a user.
        - cupsMarkOptions() now handles more non-standard
          duplexing options and choices (STR #915)
        - cups-lpd now honors remote banner requests with the
          "standard" banner whenever a printer does not have one
          defined (STR #1220)
        - The scheduler's denial-of-service checks did not work
          properly with IPv6 addresses (STR #1134)
        - The lp and lpr commands did not error out properly when
          they were unable to write to a temporary file (STR
          #1129)
        - The pstops filter did not handle Adobe-specific
          comments in Windows NT driver output (STR #1085)
        - "lpstat -l -p" incorrectly reported the printer
          interface (STR #936)
        - The web interface now operates exclusively with the
          UTF-8 encoding, and sends the appropriate character set
          and header information to the web browser (STR #919,
          STR #1007)
        - Added a "set allowed users" interface to the web
          interface so that you can set the list of allowed or
          denied users/groups for a printer or class.
        - Disallow the "#" character in printer names, since it
          has special meaning in the shell, config files, and in
          URIs (STR #917, STR #1202)
        - Added a new application/x-csource MIME type, and
          support for it to the texttops filter so that you can
          pretty print plain text files without the C/C++
          keywords being highlighted.
        - The pdftops filter did not compile with GCC 4.0 (STR
          #1226)
        - The texttops filter did not highlight preprocessor
          directives followed by a tab properly.
        - HP PJL output now uses both JOB DISPLAY and RDYMSG
          commands to show the current job on the printer's
          display (STR #1218)
        - Local authentication certificates are now stored in
          /var/run/cups/certs by default instead of
          /etc/cups/certs (STR #1211)
        - Backends now use "&" to separate options in device
          URIs; "+" is still recognized but is deprecated (STR
          #842)
        - The USB backend no longer supports the usb:/dev/foo
          format on systems that support device ID queries.
        - Forced classification markings did not work when the
          job-sheets parameters were "none,none".
        - "lpstat -l -p" incorrectly showed all users as allowed,
          even if the queue was restricted to certain users (STR
          #801)
        - The scheduler now automatically detects SSL/TLS clients
          without using the SSLPort/SSLListen directives.
        - The CUPS API and scheduler no longer support SSLv2-
          encrypted connections.
        - Updated the cupsaddsmb utility to correctly export the
          CUPS driver for Windows.
        - Fixed a signal-handling bug in httpRead() which
          ultimately caused the server to print multiple copies
          when it was busy (STR #1184)
        - The cupsFile API now uses the O_APPEND option when
          opening files in append mode (STR #990)
        - The md5.h header and md5_* functions are now officially
          private and have been renamed to avoid conflicts with
          other implementations with the same name.
        - The pdftops filter incorrectly embedded some Type1
          fonts (STR #1093)
        - The scheduler didn't detect a closed connection in the
          middle of an IPP request (STR #1153)
        - The scheduler could block trying to read the job status
          if there was input pending and the job was cancelled in
          the same input cycle (STR #1157)

          PostScript commands in a PPD file.
        - The CUPS browsing protocol now offers a "delete" bit

          (STR #793)
        - The CUPS_SERVER and ServerName directives (client.conf

          "server:port" and "/path/to/domain/socket".
        - The "cancel -u user" command now works for ordinary
          users (STR #751)

        - Added domain socket support (STR #656)
        - Added BrowseLocalOptions directive to allow the
          administrator to add printer URI options to the browse
          URI, e.g. "encryption=required" (STR #732)
        - Added BrowseRemoteOptions directive to allow the
          administrator to add standard URI options to the
          remote printer URI, e.g. "encryption=required" (STR
          #732)
        - Now put "-I.." compiler option in front of all others
          to ensure that local CUPS headers are used before

        - New cupsLangPrintf() and cupsLangPuts() for localized
          interfaces.

          PPD files.
        - Now provide functions to save PPD files.
        - New policy mechanism allows per-operation and
          per-printer control over what users and groups are
          allowed to do various IPP operations.
        - New error policy mechanism to control how aborted
          backend errors are handled by the scheduler
          (abort-job, retry-job, requeue-job, stop-printer)
        - Updated the printer test page with a better color
          wheel and a separate grayscale ramp.
        - A single backend process is now run to send all print
          data for a job.

          page data.
