CUPS 1.4 RC1 / 1.3.10

CUPS provides a portable printing layer for UNIX-based operating systems.
CUPS is a tool created and maintained by Easy Software Products to promote a standard printing solution and is the standard printing system in MacOS X and most Linux distributions.
CUPS uses the Internet Printing Protocol ("IPP") as the basis for managing print jobs and queues and adds network printer browsing and PostScript Printer Description ("PPD") based printing options to support real-world printing.

Enhancements
- 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 compilers #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.
