          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

          libpaper (STR #3205, STR #3206)

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)

        - 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.

          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

          devices (STR #3108)

          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)

          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)
        - cupsGetNamedDest() did not use the fallback default like
          cupsGetDests*() (STR #3082)
        - The scheduler now provides a LogTimeFormat directive to enable

          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
