CHANGES IN CUPS V1.4rc1

        - The PPD compiler documentation was missing information on localization
          (STR #3212)
        - The IPP backend now reconnects after every request when talking to
          printers that claim IPP support but only use HTTP/1.0.
        - The PPD compiler crashed when both "Resolution" and "Group foo Option
          Resolution" were specified in the .drv file.
        - The PPD compiler's #if/#elif/#else/#endif did not work for undefined
          variables (STR #3210)
        - Static libraries could not be installed by a non-root user on systems
          needing a ranlib program (STR #3209)
        - The scheduler incorrectly always tried to copy Kerberos credentials
          for print jobs.
        - Updated the Spanish localization (STR #3204)
        - The scheduler crashed when getting the default paper size from
          libpaper (STR #3205, STR #3206)
        - The PPD compiler now defines six variables: CUPS_VERSION,
          CUPS_VERSION_MAJOR, CUPS_VERSION_MINOR, CUPS_VERSION_PATCH,
          PLATFORM_NAME, and PLATFORM_ARCH (STR #3203)
        - Fixed a whitespace skipping bug in cupsRasterInterpretPPD.
        - The scheduler did not return HTTP 403 (Forbidden) for authenticated
          users that were not authorized to do IPP operations (STR #3193)
        - The scheduler did not report more than 8 Product strings from a PPD
          file.  Some PPD files have as many as 24.
        - ppdOpen*() could crash if a keyword had no value string (something
          that cupstestppd looks for...)
        - cupsLangDefault() did not return the correct language on Mac OS X.
        - The Mac OS X USB backend did not handle aborted or stalled pipe
          conditions properly, which prevented drivers from ejecting partial
          pages when a job was canceled or held.


CHANGES IN CUPS V1.4b3

        - Documentation fixes (STR #3044, STR #3057, STR #3153, STR #3158,
          STR #3173)
        - Added complete localizations for German, Japanese, Polish, and
          Russian and partial localizations for Chinese, Danish, Finnish,
          French, Italian, Korean, Norwegian, Portuguese, and Swedish
          (STR #3096, STR #3098, STR #3109, STR #3111, STR #3141)
        - Updated the configure check for -fstack-protector (STR #3198)
        - The network backends now correctly convert SNMP supply descriptions to
          UTF-8 encoding as needed.
        - The scheduler could crash when deleting an attribute (STR #3197)
        - The cups-driverd program did not detect symlink loops (STR #3185)
        - The EPSON 24-pin series driver should now feed the correct amount
          (STR #2624)
        - The scheduler now automatically logs the last N debug messages for
          failed print jobs.
        - You can now modify a raw print queue (STR #3133)
        - Fixed a number of ppdi issues and added a unit test to validate that
          ppdc + ppdi can generate and import the same data (STR #3152)
        - Moving jobs in the web interface now shows an error if you only have
          one printer or class added (STR #3094)
        - Since classes have never truly supported the printer-error-policy
          stuff added in CUPS 1.2, update the code to reflect the current
          reality and support only the retry-current-job policy for now
          (STR #3171)
        - Revised the password callback support (STR #2953)
        - ppdEmit*() did not choose between PageSize and PageRegion properly.
        - Make some fairly substantial changes to the Kerberos support code so
          that CUPS can work in multi-realm environments and does not require
          delegatable credentials.  Shared printing still requires delegation,
          however "delegation by policy" can be enabled in the KDC to make this
          all work.
        - "AccessLogLevel actions" did not hide client-error-not-found errors.
        - AP_FIRST_InputSlot did not work with number-up.
        - cupsBackChannelRead() and cupsBackChannelWrite() could fail due to a
          lack of kernel buffers.
        - The IPP and LPD backends did not respond to side-channel requests
          while copying print data to a temporary file.
        - cupsWriteRequestData() flushed the output buffer unnecessarily,
          causing reduced performance in some situations.
        - If a CGI process died before sending its MIME headers, the request
          would hang on the client.
        - The printer/class/job search feature on the web interface did not
          work (STR #3132)
        - The scheduler did not write the printers out for classes.
        - CUPS-Get-PPDs did not work properly when filtering by language,
          product, or psversion (STR #3136)
        - The scheduler now kills job filters when it takes more than 30 seconds
          (configurable) to cancel or hold the job.
        - The cupstestppd program did not validate the capitalization of
          filenames in the PPD file.

          device URI.
        - The scheduler now supports JobRetryInterval values less than 10
          seconds.
        - Updated the Spanish localization (STR #3090)
        - The scheduler did not redo Bonjour/DNS-SD registrations when updating
          them failed.
        - The "authenticated" policy incorrectly required authentication for
          status operations.
        - ppdOpen*() incorrectly loaded PPDs with multiple JobPatchFile
          keywords.
        - The network backends no longer report the SNMP "offline" or
          maintenance status bits since they are inconsistently implemented and
          often unreliable.
        - The scheduler no longer logs child processes killed via SIGKILL as
          "crashed".
        - The printer link shown on the "job moved" template was bad (STR #3085)
        - Updated the HTML templates to use the final HTML 4 DOCTYPE (STR #3086)

          printer had other reasons associated with it.
        - cupsSendRequest() did not clear old local certificate auth data.
        - The PPD compiler did not search for localization files properly
          (STR #3084)

        - The scheduler now provides a MultipleOperationTimeout directive to
          control the timeout for multi-file print jobs.
        - The configure script incorrectly allowed Avahi to be used for DNS-SD

        - The scheduler incorrectly registered default profiles for PostScript
          printers with no specified colorspace.
        - The scheduler incorrectly created an empty org.cups.printers.plist
          file on Mac OS X.
        - cupsGetPPD3() did not look for local PPDs in the right directory.

        - Updated the Spanish localization (STR #3043)
        - Fixed build problems (STR #3040, STR #3047)
        - cupsResolveConflicts() did not resolve using the default option
          choice in some cases due to the mirror UIConstraints that are
          present in most PPD files.
        - The scheduler did not honor MIME type priorities.
        - The commandtops filter incorrectly used the JCLBegin code to end
          its jobs.
        - The default BrowseLocalProtocols value was not set properly.
        - Since the commandtops filter does not actually support ReportLevels
          all on its own, don't list that printer command by default for PS
