  10           (STR #3096, STR #3098, STR #3109, STR #3111, STR #3141)
  11         - cupsWriteRequestData() flushed the output buffer unnecessarily,
  12           causing reduced performance in some situations.
  13         - If a CGI process died before sending its MIME headers, the request
  14           would hang on the client.

  16           work (STR #3132)
  17         - The scheduler did not write the printers out for classes.
  18         - CUPS-Get-PPDs did not work properly when filtering by language,
  19           product, or psversion (STR #3136)

  31           incorrectly added the printer (STR #3095)
  32         - The scheduler no longer uses programs with insecure file
  33           permissions.

  45           keywords.
  46         - The network backends no longer report the SNMP "offline" status bit
  47           since some printers report this status when the printer is busy
  48           printing, warming up, etc.
  49         - The scheduler no longer logs child processes killed via SIGKILL as
  50           "crashed".

  61           microseconds in the date and time that are logged.
  62         - The scheduler now provides a MultipleOperationTimeout directive to

  79           for some PPDs.
  80         - The ppdi utility did not work.
  81         - The web interface no longer uses multi-part output with old or broken
  82           web browsers (STR #3049)

  93         - The scheduler did not honor MIME type priorities.
  94         - The commandtops filter incorrectly used the JCLBegin code to end
  95           its jobs.
  96         - The default BrowseLocalProtocols value was not set properly.
  97         - Since the commandtops filter does not actually support ReportLevels

  99           printers.
 100         - The scheduler did not give filters a chance to log errors or update
 101           printer attributes when a job was canceled.
 102         - The scheduler did not clear the "connecting-to-device" reason keyword
