Release Notes

CUPS 1.4rc1 (June 8, 2009)

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)

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 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.

CUPS 1.4b3 (May 19, 2009)

Documentation fixes (STR #3044, STR #3057, STR #3153, STR #3158, STR #3173)

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.

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.

SNMP lookups via side-channel did not work for NULL-VALUE and and OCTET-STRING OIDs containing nul characters.
The libusb-based USB backend did not work.
The scheduler did not set the printer-commands attribute correctly for some PPDs.
The ppdi utility did not work.
The web interface no longer uses multi-part output with old or broken web browsers (STR #3049)

The scheduler did not honor MIME type priorities.

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 printers.
