CHANGES IN CUPS V1.2rc3

        - The cups-lpd program always did reverse lookups on the

          properly, leading to a bad select() for multi-file jobs
          (STR #1559)

          queue is missing on startup (STR #1265)
        - The configure script now supports "--disable-library"
          to disable particular image file format support
          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)

          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

          "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)
        - The scheduler could crash when deleting a class due to
          infinite recursion.
        - Updated the Zebra ZPL label printer driver to use the
          run-length encoding and support more options.
        - Updated serial backend to scan for /dev/ttyC* as well
          as /dev/ttyc* for Cyclades serial ports (STR #1049)

          (STR #1046)
        - Moved enable and disable commands to sbindir to be
          consistent.
        - Added new cupsRasterInterpretPPD() function for RIP
          filters to setup the raster page header from
          PostScript commands in a PPD file.
        - The CUPS browsing protocol now offers a "delete" bit
          to remove printers as soon as they are deleted on the
          server or as soon as the server shuts down gracefully
          (STR #793)
        - The CUPS_SERVER and ServerName directives (client.conf
          and ~/.cupsrc) may now contain names of the form
          "server:port" and "/path/to/domain/socket".
        - The "cancel -u user" command now works for ordinary
          users (STR #751)
        - Added test run support to "make test" target (STR #64)

          backchannel data over file descriptor 3.
        - Updated the raster stream format to support more
