 128         - The scheduler did not minimize the number of printer state events that

 150           needing a ranlib program (STR #3209)

 164         - ppdOpen*() could crash if a keyword had no value string (something
 165           that cupstestppd looks for...)
 166         - cupsLangDefault() did not return the correct language on Mac OS X.
 167         - The Mac OS X USB backend did not handle aborted or stalled pipe
 168           conditions properly, which prevented drivers from ejecting partial

 179           (STR #3096, STR #3098, STR #3109, STR #3111, STR #3141)
 180         - Updated the configure check for -fstack-protector (STR #3198)
 181         - The network backends now correctly convert SNMP supply descriptions to
 182           UTF-8 encoding as needed.
 183         - The scheduler could crash when deleting an attribute (STR #3197)

 187         - The scheduler now automatically logs the last N debug messages for
 188           failed print jobs.
 189         - You can now modify a raw print queue (STR #3133)
 190         - Fixed a number of ppdi issues and added a unit test to validate that
 191           ppdc + ppdi can generate and import the same data (STR #3152)
 192         - Moving jobs in the web interface now shows an error if you only have
 193           one printer or class added (STR #3094)
 194         - Since classes have never truly supported the printer-error-policy
 195           stuff added in CUPS 1.2, update the code to reflect the current
 196           reality and support only the retry-current-job policy for now
 197           (STR #3171)
 198         - Revised the password callback support (STR #2953)
 199         - ppdEmit*() did not choose between PageSize and PageRegion properly.
 200         - Make some fairly substantial changes to the Kerberos support code so
 201           that CUPS can work in multi-realm environments and does not require
 202           delegatable credentials.  Shared printing still requires delegation,
 203           however "delegation by policy" can be enabled in the KDC to make this
 204           all work.
 205         - "AccessLogLevel actions" did not hide client-error-not-found errors.
 206         - AP_FIRST_InputSlot did not work with number-up.
 207         - cupsBackChannelRead() and cupsBackChannelWrite() could fail due to a
 208           lack of kernel buffers.
 209         - The IPP and LPD backends did not respond to side-channel requests
 210           while copying print data to a temporary file.
 211         - cupsWriteRequestData() flushed the output buffer unnecessarily,
 212           causing reduced performance in some situations.
 213         - If a CGI process died before sending its MIME headers, the request
 214           would hang on the client.
 215         - The printer/class/job search feature on the web interface did not
 216           work (STR #3132)
 217         - The scheduler did not write the printers out for classes.
 218         - CUPS-Get-PPDs did not work properly when filtering by language,
 219           product, or psversion (STR #3136)

 221           (configurable) to cancel or hold the job.
 222         - The cupstestppd program did not validate the capitalization of
 223           filenames in the PPD file.

 225           values.

 229         - The scheduler could consume 100% CPU when jobs were canceled.
 230         - Clicking on "Select Another Make/Manufacturer" in the web interface
 231           incorrectly added the printer (STR #3095)
 232         - The scheduler no longer uses programs with insecure file
 233           permissions.
 234         - httpAssembleURI*() did not escape backslashes in hostnames.
 235         - The dnssd backend did not unquote "full names" before creating the
 236           device URI.
 237         - The scheduler now supports JobRetryInterval values less than 10
 238           seconds.
 239         - Updated the Spanish localization (STR #3090)
 240         - The scheduler did not redo Bonjour/DNS-SD registrations when updating
 241           them failed.
 242         - The "authenticated" policy incorrectly required authentication for
 243           status operations.
 244         - ppdOpen*() incorrectly loaded PPDs with multiple JobPatchFile
 245           keywords.
 246         - The network backends no longer report the SNMP "offline" or
 247           maintenance status bits since they are inconsistently implemented and
 248           often unreliable.
 249         - The scheduler no longer logs child processes killed via SIGKILL as
 250           "crashed".
 251         - The printer link shown on the "job moved" template was bad (STR #3085)
 252         - Updated the HTML templates to use the final HTML 4 DOCTYPE (STR #3086)
 253         - The scheduler did not track the "paused" reason properly if a

 256         - The PPD compiler did not search for localization files properly
 257           (STR #3084)
 258         - cupsGetNamedDest() did not use the fallback default like
 259           cupsGetDests*() (STR #3082)
 260         - The scheduler now provides a LogTimeFormat directive to enable
 261           microseconds in the date and time that are logged.
 262         - The scheduler now provides a MultipleOperationTimeout directive to
 263           control the timeout for multi-file print jobs.

 265           printer discovery (STR #3065)

 274         - cupsGetPPD3() did not look for local PPDs in the right directory.
 275         - SNMP lookups via side-channel did not work for NULL-VALUE and
 276           and OCTET-STRING OIDs containing nul characters.
 277         - The libusb-based USB backend did not work.
 278         - The scheduler did not set the printer-commands attribute correctly
 279           for some PPDs.
 280         - The ppdi utility did not work.
 281         - The web interface no longer uses multi-part output with old or broken

 289         - Fixed build problems (STR #3040, STR #3047)
 290         - cupsResolveConflicts() did not resolve using the default option
 291           choice in some cases due to the mirror UIConstraints that are
 292           present in most PPD files.
 293         - The scheduler did not honor MIME type priorities.
 294         - The commandtops filter incorrectly used the JCLBegin code to end
 295           its jobs.
 296         - The default BrowseLocalProtocols value was not set properly.
 297         - Since the commandtops filter does not actually support ReportLevels
 298           all on its own, don't list that printer command by default for PS
 299           printers.
 300         - The scheduler did not give filters a chance to log errors or update
 301           printer attributes when a job was canceled.
 302         - The scheduler did not clear the "connecting-to-device" reason keyword
 303           when a job finished.

 311         - The default cupsd.conf file did not reflect the
 312           --with-local-protocols value set at compile-time (STR #3037)
 313         - The cupsGetPPD* APIs now create symlinks to local PPD files
 314           rather than copying them whenever possible.
