	  one printer or class added (STR #3094)

	- 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,

	  all work.
	- "AccessLogLevel actions" did not hide client-error-not-found errors.
	- AP_FIRST_InputSlot did not work with number-up.

	  values.
	- The cups-deviced helper program could miss reporting some backend
	  devices (STR #3108)
	- The cupsSideChannelSNMP* functions did not work.
	- The scheduler could consume 100% CPU when jobs were canceled.
	- Clicking on "Select Another Make/Manufacturer" in the web interface

	  permissions.

	  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)
	- The scheduler did not track the "paused" reason properly if a
	  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
	  microseconds in the date and time that are logged.
	- 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
	  printer discovery (STR #3065)

	  in length (STR #3072)
	- Fixed pdftops issues with page sizes (STR #3063)

	- 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.
	- SNMP lookups via side-channel did not work for NULL-VALUE and
	  and OCTET-STRING OIDs containing nul characters.

	- The scheduler did not set the printer-commands attribute correctly
	  for some PPDs.
	- The ppdi utility did not work.

	  web browsers (STR #3049)
	- CUPS now conforms to the draft IPP/2.0 and IPP/2.1 specification.

	  have associated translation text (STR #3045)
	- 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
	  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.

        - The CUPS-Get-Devices operation now supports the include-schemes
	  attribute.
	- The print filters now support a replacement for the fitplot
