   4 CHANGES IN CUPS V1.4b3
   5
   6         - Documentation fixes (STR #3044, STR #3057)
   7         - Added complete localizations for German, Japanese, Polish, and
   8           Russian and partial localizations for Chinese, Danish, Finnish,
   9           French, Italian, Korean, Norwegian, Portuguese, and Swedish
  10           (STR #3096, STR #3098, STR #3109, STR #3111, STR #3141)
  11         - Make some fairly substantial changes to the Kerberos support code so
  12           that CUPS can work in multi-realm environments and does not require
  13           delegatable credentials.  Shared printing still requires delegation,
  14           however "delegation by policy" can be enabled in the KDC to make this
  15           all work.
  16         - "AccessLogLevel actions" did not hide client-error-not-found errors.
  17         - AP_FIRST_InputSlot did not work with number-up.
  18         - cupsBackChannelRead() and cupsBackChannelWrite() could fail due to a
  19           lack of kernel buffers.
  20         - The IPP and LPD backends did not respond to side-channel requests
  21           while copying print data to a temporary file.
  22         - cupsWriteRequestData() flushed the output buffer unnecessarily,
  23           causing reduced performance in some situations.
  24         - If a CGI process died before sending its MIME headers, the request
  25           would hang on the client.
  26         - The printer/class/job search feature on the web interface did not
  27           work (STR #3132)
  28         - The scheduler did not write the printers out for classes.
  29         - CUPS-Get-PPDs did not work properly when filtering by language,
  30           product, or psversion (STR #3136)
  31         - The scheduler now kills job filters when it takes more than 30 seconds
  32           (configurable) to cancel or hold the job.
  33         - The cupstestppd program did not validate the capitalization of
  34           filenames in the PPD file.
  35         - The cupstestppd program did not validate the PageSize and PageRegion
  36           values.
  37         - The cups-deviced helper program could miss reporting some backend
  38           devices (STR #3108)
  39         - The cupsSideChannelSNMP* functions did not work.
  40         - The scheduler could consume 100% CPU when jobs were canceled.
  41         - Clicking on "Select Another Make/Manufacturer" in the web interface
  42           incorrectly added the printer (STR #3095)
  43         - The scheduler no longer uses programs with insecure file
  44           permissions.
  45         - httpAssembleURI*() did not escape backslashes in hostnames.
  46         - The dnssd backend did not unquote "full names" before creating the
  47           device URI.
  48         - The scheduler now supports JobRetryInterval values less than 10
  49           seconds.
  50         - Updated the Spanish localization (STR #3090)
  51         - The scheduler did not redo Bonjour/DNS-SD registrations when updating
  52           them failed.
  53         - The "authenticated" policy incorrectly required authentication for
  54           status operations.
  55         - ppdOpen*() incorrectly loaded PPDs with multiple JobPatchFile
  56           keywords.
  57         - The network backends no longer report the SNMP "offline" or
  58           maintenance status bits since they are inconsistently implemented and
  59           often unreliable.
  60         - The scheduler no longer logs child processes killed via SIGKILL as
  61           "crashed".

  63         - Updated the HTML templates to use the final HTML 4 DOCTYPE (STR #3086)
  64         - The scheduler did not track the "paused" reason properly if a

  66         - cupsSendRequest() did not clear old local certificate auth data.
  67         - The PPD compiler did not search for localization files properly
  68           (STR #3084)
  69         - cupsGetNamedDest() did not use the fallback default like
  70           cupsGetDests*() (STR #3082)
  71         - The scheduler now provides a LogTimeFormat directive to enable
  72           microseconds in the date and time that are logged.
  73         - The scheduler now provides a MultipleOperationTimeout directive to
  74           control the timeout for multi-file print jobs.

  76           printer discovery (STR #3065)
  77         - The web interface and scheduler did not support URIs up to 1024 bytes
  78           in length (STR #3072)

  85         - cupsGetPPD3() did not look for local PPDs in the right directory.
  86         - SNMP lookups via side-channel did not work for NULL-VALUE and
  87           and OCTET-STRING OIDs containing nul characters.
  88         - The libusb-based USB backend did not work.
  89         - The scheduler did not set the printer-commands attribute correctly
  90           for some PPDs.
  91         - The ppdi utility did not work.
  92         - The web interface no longer uses multi-part output with old or broken
  93           web browsers (STR #3049)
  94         - CUPS now conforms to the draft IPP/2.0 and IPP/2.1 specification.
  95         - Added a new cupsGetConflicts() API to get a list of conflicting

  97         - The PPD compiler didn't localize options or choices that did not
  98           have associated translation text (STR #3045)
  99         - Updated the Spanish localization (STR #3043)
 100         - Fixed build problems (STR #3040, STR #3047)
 101         - cupsResolveConflicts() did not resolve using the default option
 102           choice in some cases due to the mirror UIConstraints that are
 103           present in most PPD files.
 104         - The scheduler did not honor MIME type priorities.
 105         - The commandtops filter incorrectly used the JCLBegin code to end
 106           its jobs.
 107         - The default BrowseLocalProtocols value was not set properly.
 108         - Since the commandtops filter does not actually support ReportLevels
 109           all on its own, don't list that printer command by default for PS
 110           printers.
 111         - The scheduler did not give filters a chance to log errors or update
 112           printer attributes when a job was canceled.
 113         - The scheduler did not clear the "connecting-to-device" reason keyword
 114           when a job finished.

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