 133           that cupstestppd looks for...)
 134         - cupsLangDefault() did not return the correct language on Mac OS X.
 135         - The Mac OS X USB backend did not handle aborted or stalled pipe

 155         - The scheduler now automatically logs the last N debug messages for
 156           failed print jobs.
 157         - You can now modify a raw print queue (STR #3133)
 158         - Fixed a number of ppdi issues and added a unit test to validate that
 159           ppdc + ppdi can generate and import the same data (STR #3152)
 160         - Moving jobs in the web interface now shows an error if you only have
 161           one printer or class added (STR #3094)
 162         - Since classes have never truly supported the printer-error-policy
 163           stuff added in CUPS 1.2, update the code to reflect the current
 164           reality and support only the retry-current-job policy for now
 165           (STR #3171)
 166         - Revised the password callback support (STR #2953)
 167         - ppdEmit*() did not choose between PageSize and PageRegion properly.
 168         - Make some fairly substantial changes to the Kerberos support code so
 169           that CUPS can work in multi-realm environments and does not require
 170           delegatable credentials.  Shared printing still requires delegation,
 171           however "delegation by policy" can be enabled in the KDC to make this
 172           all work.
 173         - "AccessLogLevel actions" did not hide client-error-not-found errors.
 174         - AP_FIRST_InputSlot did not work with number-up.

 176           lack of kernel buffers.
 177         - The IPP and LPD backends did not respond to side-channel requests
 178           while copying print data to a temporary file.
 179         - cupsWriteRequestData() flushed the output buffer unnecessarily,
 180           causing reduced performance in some situations.
 181         - If a CGI process died before sending its MIME headers, the request
 182           would hang on the client.
 183         - The printer/class/job search feature on the web interface did not
 184           work (STR #3132)
 185         - The scheduler did not write the printers out for classes.
 186         - CUPS-Get-PPDs did not work properly when filtering by language,
 187           product, or psversion (STR #3136)

 189           (configurable) to cancel or hold the job.
 190         - The cupstestppd program did not validate the capitalization of
 191           filenames in the PPD file.

 197         - The scheduler could consume 100% CPU when jobs were canceled.
 198         - Clicking on "Select Another Make/Manufacturer" in the web interface
 199           incorrectly added the printer (STR #3095)
 200         - The scheduler no longer uses programs with insecure file
 201           permissions.
 202         - httpAssembleURI*() did not escape backslashes in hostnames.
 203         - The dnssd backend did not unquote "full names" before creating the
 204           device URI.
 205         - The scheduler now supports JobRetryInterval values less than 10
 206           seconds.
 207         - Updated the Spanish localization (STR #3090)
 208         - The scheduler did not redo Bonjour/DNS-SD registrations when updating

 212         - ppdOpen*() incorrectly loaded PPDs with multiple JobPatchFile
 213           keywords.
 214         - The network backends no longer report the SNMP "offline" or
 215           maintenance status bits since they are inconsistently implemented and
 216           often unreliable.
 217         - The scheduler no longer logs child processes killed via SIGKILL as
 218           "crashed".

 224         - The PPD compiler did not search for localization files properly
 225           (STR #3084)
 226         - cupsGetNamedDest() did not use the fallback default like
 227           cupsGetDests*() (STR #3082)
 228         - The scheduler now provides a LogTimeFormat directive to enable
 229           microseconds in the date and time that are logged.
 230         - The scheduler now provides a MultipleOperationTimeout directive to
 231           control the timeout for multi-file print jobs.

 242         - cupsGetPPD3() did not look for local PPDs in the right directory.
 243         - SNMP lookups via side-channel did not work for NULL-VALUE and
 244           and OCTET-STRING OIDs containing nul characters.
 245         - The libusb-based USB backend did not work.
 246         - The scheduler did not set the printer-commands attribute correctly
 247           for some PPDs.
 248         - The ppdi utility did not work.
 249         - The web interface no longer uses multi-part output with old or broken

 260           present in most PPD files.
 261         - The scheduler did not honor MIME type priorities.
 262         - The commandtops filter incorrectly used the JCLBegin code to end
 263           its jobs.
 264         - The default BrowseLocalProtocols value was not set properly.
 265         - Since the commandtops filter does not actually support ReportLevels
 266           all on its own, don't list that printer command by default for PS
 267           printers.
 268         - The scheduler did not give filters a chance to log errors or update
 269           printer attributes when a job was canceled.
 270         - The scheduler did not clear the "connecting-to-device" reason keyword
 271           when a job finished.

 275
 276         - Documentation updates (STR #2983, STR #2998, STR #3021)
 277         - The cupstestppd utility now validates the FileVersion and
 278           FormatVersion values in PPD files.
 279         - The default cupsd.conf file did not reflect the
 280           --with-local-protocols value set at compile-time (STR #3037)
 281         - The cupsGetPPD* APIs now create symlinks to local PPD files
 282           rather than copying them whenever possible.
 283         - Various performance optimizations in the string pool, dests, and
 284           options implementations.
 285         - The cupsGetDests* APIs now return the marker and printer-commands
 286           attributes.
 287         - Side-channel SNMP lookups would not work when cupsSNMPSupplies
 288           was set to False in the PPD file.
 289         - Localized the device descriptions for the SCSI, serial,
 290           and network backends (STR #3014)
 291         - Added a Spanish localization (STR #3015)
