   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         - Fixed a number of ppdi issues and added a unit test to validate that
  12           ppdc + ppdi can generate and import the same data (STR #3152)
  13         - Moving jobs in the web interface now shows an error if you only have
  14           one printer or class added (STR #3094)
  15         - Since classes have never truly supported the printer-error-policy
  16           stuff added in CUPS 1.2, update the code to reflect the current
  17           reality and support only the retry-current-job policy for now
  18           (STR #3171)
  19         - Revised the password callback support (STR #2953)
  20         - ppdEmit*() did not choose between PageSize and PageRegion properly.
  21         - Make some fairly substantial changes to the Kerberos support code so
  22           that CUPS can work in multi-realm environments and does not require
  23           delegatable credentials.  Shared printing still requires delegation,
  24           however "delegation by policy" can be enabled in the KDC to make this
  25           all work.
  26         - "AccessLogLevel actions" did not hide client-error-not-found errors.
  27         - AP_FIRST_InputSlot did not work with number-up.
  28         - cupsBackChannelRead() and cupsBackChannelWrite() could fail due to a
  29           lack of kernel buffers.
  30         - The IPP and LPD backends did not respond to side-channel requests
  31           while copying print data to a temporary file.
  32         - cupsWriteRequestData() flushed the output buffer unnecessarily,
  33           causing reduced performance in some situations.
  34         - If a CGI process died before sending its MIME headers, the request
  35           would hang on the client.
  36         - The printer/class/job search feature on the web interface did not
  37           work (STR #3132)
  38         - The scheduler did not write the printers out for classes.
  39         - CUPS-Get-PPDs did not work properly when filtering by language,
  40           product, or psversion (STR #3136)
  41         - The scheduler now kills job filters when it takes more than 30 seconds
  42           (configurable) to cancel or hold the job.
  43         - The cupstestppd program did not validate the capitalization of
  44           filenames in the PPD file.
  45         - The cupstestppd program did not validate the PageSize and PageRegion
  46           values.
  47         - The cups-deviced helper program could miss reporting some backend
  48           devices (STR #3108)
  49         - The cupsSideChannelSNMP* functions did not work.
  50         - The scheduler could consume 100% CPU when jobs were canceled.
  51         - Clicking on "Select Another Make/Manufacturer" in the web interface
  52           incorrectly added the printer (STR #3095)
  53         - The scheduler no longer uses programs with insecure file
  54           permissions.
  55         - httpAssembleURI*() did not escape backslashes in hostnames.
  56         - The dnssd backend did not unquote "full names" before creating the
  57           device URI.
  58         - The scheduler now supports JobRetryInterval values less than 10
  59           seconds.
  60         - Updated the Spanish localization (STR #3090)
  61         - The scheduler did not redo Bonjour/DNS-SD registrations when updating
  62           them failed.
  63         - The "authenticated" policy incorrectly required authentication for
  64           status operations.
  65         - ppdOpen*() incorrectly loaded PPDs with multiple JobPatchFile
  66           keywords.
  67         - The network backends no longer report the SNMP "offline" or
  68           maintenance status bits since they are inconsistently implemented and
  69           often unreliable.
  70         - The scheduler no longer logs child processes killed via SIGKILL as
  71           "crashed".

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

  76         - cupsSendRequest() did not clear old local certificate auth data.
  77         - The PPD compiler did not search for localization files properly
  78           (STR #3084)
  79         - cupsGetNamedDest() did not use the fallback default like
  80           cupsGetDests*() (STR #3082)
  81         - The scheduler now provides a LogTimeFormat directive to enable
  82           microseconds in the date and time that are logged.
  83         - The scheduler now provides a MultipleOperationTimeout directive to
  84           control the timeout for multi-file print jobs.
  85         - The configure script incorrectly allowed Avahi to be used for DNS-SD
  86           printer discovery (STR #3065)
  87         - The web interface and scheduler did not support URIs up to 1024 bytes
  88           in length (STR #3072)

  95         - cupsGetPPD3() did not look for local PPDs in the right directory.
  96         - SNMP lookups via side-channel did not work for NULL-VALUE and
  97           and OCTET-STRING OIDs containing nul characters.
  98         - The libusb-based USB backend did not work.
  99         - The scheduler did not set the printer-commands attribute correctly
 100           for some PPDs.
 101         - The ppdi utility did not work.
 102         - The web interface no longer uses multi-part output with old or broken
 103           web browsers (STR #3049)
 104         - CUPS now conforms to the draft IPP/2.0 and IPP/2.1 specification.
 105         - Added a new cupsGetConflicts() API to get a list of conflicting
 106           options.
 107         - The PPD compiler didn't localize options or choices that did not
 108           have associated translation text (STR #3045)
 109         - Updated the Spanish localization (STR #3043)
 110         - Fixed build problems (STR #3040, STR #3047)
 111         - cupsResolveConflicts() did not resolve using the default option
 112           choice in some cases due to the mirror UIConstraints that are
 113           present in most PPD files.
 114         - The scheduler did not honor MIME type priorities.
 115         - The commandtops filter incorrectly used the JCLBegin code to end
 116           its jobs.
 117         - The default BrowseLocalProtocols value was not set properly.
 118         - Since the commandtops filter does not actually support ReportLevels
 119           all on its own, don't list that printer command by default for PS
 120           printers.
 121         - The scheduler did not give filters a chance to log errors or update
 122           printer attributes when a job was canceled.
 123         - The scheduler did not clear the "connecting-to-device" reason keyword
 124           when a job finished.

 134         - The cupsGetPPD* APIs now create symlinks to local PPD files
 135           rather than copying them whenever possible.
