   4 CHANGES IN CUPS V1.4rc1
   5
   6         - The PPD compiler now defines six variables: CUPS_VERSION,
   7           CUPS_VERSION_MAJOR, CUPS_VERSION_MINOR, CUPS_VERSION_PATCH,
   8           PLATFORM_NAME, and PLATFORM_ARCH (STR #3203)
   9         - Fixed a whitespace skipping bug in cupsRasterInterpretPPD.
  10         - The scheduler did not return HTTP 403 (Forbidden) for authenticated
  11           users that were not authorized to do IPP operations (STR #3193)
  12         - The scheduler did not report more than 8 Product strings from a PPD
  13           file.  Some PPD files have as many as 24.
  14         - ppdOpen*() could crash if a keyword had no value string (something
  15           that cupstestppd looks for...)
  16         - cupsLangDefault() did not return the correct language on Mac OS X.
  17         - The Mac OS X USB backend did not handle aborted or stalled pipe
  18           conditions properly, which prevented drivers from ejecting partial
  19           pages when a job was canceled or held.

  22 CHANGES IN CUPS V1.4b3
  23
  24         - Documentation fixes (STR #3044, STR #3057, STR #3153, STR #3158,
  25           STR #3173)
  26         - Added complete localizations for German, Japanese, Polish, and
  27           Russian and partial localizations for Chinese, Danish, Finnish,
  28           French, Italian, Korean, Norwegian, Portuguese, and Swedish
  29           (STR #3096, STR #3098, STR #3109, STR #3111, STR #3141)
  30         - Updated the configure check for -fstack-protector (STR #3198)
  31         - The network backends now correctly convert SNMP supply descriptions to
  32           UTF-8 encoding as needed.
  33         - The scheduler could crash when deleting an attribute (STR #3197)
  34         - The cups-driverd program did not detect symlink loops (STR #3185)
  35         - The EPSON 24-pin series driver should now feed the correct amount
  36           (STR #2624)
  37         - The scheduler now automatically logs the last N debug messages for
  38           failed print jobs.
  39         - You can now modify a raw print queue (STR #3133)
  40         - Fixed a number of ppdi issues and added a unit test to validate that
  41           ppdc + ppdi can generate and import the same data (STR #3152)
  42         - Moving jobs in the web interface now shows an error if you only have
  43           one printer or class added (STR #3094)
  44         - Since classes have never truly supported the printer-error-policy
  45           stuff added in CUPS 1.2, update the code to reflect the current
  46           reality and support only the retry-current-job policy for now
  47           (STR #3171)
  48         - Revised the password callback support (STR #2953)
  49         - ppdEmit*() did not choose between PageSize and PageRegion properly.
  50         - Make some fairly substantial changes to the Kerberos support code so
  51           that CUPS can work in multi-realm environments and does not require
  52           delegatable credentials.  Shared printing still requires delegation,
  53           however "delegation by policy" can be enabled in the KDC to make this
  54           all work.
  55         - "AccessLogLevel actions" did not hide client-error-not-found errors.
  56         - AP_FIRST_InputSlot did not work with number-up.
  57         - cupsBackChannelRead() and cupsBackChannelWrite() could fail due to a
  58           lack of kernel buffers.
  59         - The IPP and LPD backends did not respond to side-channel requests
  60           while copying print data to a temporary file.
  61         - cupsWriteRequestData() flushed the output buffer unnecessarily,
  62           causing reduced performance in some situations.
  63         - If a CGI process died before sending its MIME headers, the request
  64           would hang on the client.
  65         - The printer/class/job search feature on the web interface did not
  66           work (STR #3132)
  67         - The scheduler did not write the printers out for classes.
  68         - CUPS-Get-PPDs did not work properly when filtering by language,
  69           product, or psversion (STR #3136)
  70         - The scheduler now kills job filters when it takes more than 30 seconds
  71           (configurable) to cancel or hold the job.
  72         - The cupstestppd program did not validate the capitalization of
  73           filenames in the PPD file.
  74         - The cupstestppd program did not validate the PageSize and PageRegion
  75           values.

  79         - The scheduler could consume 100% CPU when jobs were canceled.
  80         - Clicking on "Select Another Make/Manufacturer" in the web interface
  81           incorrectly added the printer (STR #3095)
  82         - The scheduler no longer uses programs with insecure file
  83           permissions.
  84         - httpAssembleURI*() did not escape backslashes in hostnames.
  85         - The dnssd backend did not unquote "full names" before creating the
  86           device URI.
  87         - The scheduler now supports JobRetryInterval values less than 10
  88           seconds.
  89         - Updated the Spanish localization (STR #3090)
  90         - The scheduler did not redo Bonjour/DNS-SD registrations when updating

  94         - ppdOpen*() incorrectly loaded PPDs with multiple JobPatchFile
  95           keywords.
  96         - The network backends no longer report the SNMP "offline" or
  97           maintenance status bits since they are inconsistently implemented and
  98           often unreliable.
  99         - The scheduler no longer logs child processes killed via SIGKILL as
 100           "crashed".

 106         - The PPD compiler did not search for localization files properly
 107           (STR #3084)
 108         - cupsGetNamedDest() did not use the fallback default like
 109           cupsGetDests*() (STR #3082)
 110         - The scheduler now provides a LogTimeFormat directive to enable
 111           microseconds in the date and time that are logged.
 112         - The scheduler now provides a MultipleOperationTimeout directive to
 113           control the timeout for multi-file print jobs.

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

 139         - Fixed build problems (STR #3040, STR #3047)
 140         - cupsResolveConflicts() did not resolve using the default option
 141           choice in some cases due to the mirror UIConstraints that are
 142           present in most PPD files.
 143         - The scheduler did not honor MIME type priorities.
 144         - The commandtops filter incorrectly used the JCLBegin code to end
 145           its jobs.
 146         - The default BrowseLocalProtocols value was not set properly.
 147         - Since the commandtops filter does not actually support ReportLevels
 148           all on its own, don't list that printer command by default for PS
 149           printers.
 150         - The scheduler did not give filters a chance to log errors or update
 151           printer attributes when a job was canceled.
 152         - The scheduler did not clear the "connecting-to-device" reason keyword
 153           when a job finished.

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