------------------------

CHANGES IN CUPS V1.4b3

	- CUPS now conforms to the draft IPP/2.0 and IPP/2.1 specification.
	- 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
	  printers.
	- The scheduler did not give filters a chance to log errors or update
	  printer attributes when a job was canceled.
	- The scheduler did not clear the "connecting-to-device" reason keyword
	  when a job finished.


CHANGES IN CUPS V1.4b2

	- Documentation updates (STR #2983, STR #2998, STR #3021)
	- The cupstestppd utility now validates the FileVersion and
	  FormatVersion values in PPD files.
	- The default cupsd.conf file did not reflect the
	  --with-local-protocols value set at compile-time (STR #3037)
	- The cupsGetPPD* APIs now create symlinks to local PPD files
	  rather than copying them whenever possible.
	- Various performance optimizations in the string pool, dests, and
	  options implementations.
	- The cupsGetDests* APIs now return the marker and printer-commands
	  attributes.
	- Side-channel SNMP lookups would not work when cupsSNMPSupplies
	  was set to False in the PPD file.
	- Localized the device descriptions for the SCSI, serial,
	  and network backends (STR #3014)
	- Added a Spanish localization (STR #3015)
	- Added support for marker-low-levels and marker-high-levels
	  attributes.

        - The CUPS-Get-Devices operation now supports the include-schemes
	  attribute.
	- The print filters now support a replacement for the fitplot
	  option called "fit-to-page".
	- The LPD backend no longer tries to collect page accounting
	  information since the LPD protocol does not allow us to
	  prevent race conditions.
	- The scheduler did not save the last marker-change-time value.
	- Fixed a problem with printing to some IPP printers, including
	  CUPS 1.1.x.
	- Fixed a redirection problem with the printer web page (STR #3012)
