  17         - The scheduler no longer uses chunking in responses to
  18           clients - this caused problems with older versions of

  38         - The configure script did not use the GNU TLS

  48           public header.

  50           encoding rules and colorspace definitions.
  51         - The Zebra PPD files had the wrong PostScript code for
  52           the "default" option choices.
  53         - The imagetoraster filter did not generate correct CIE
  54           XYZ or Lab color data.
  55         - The cups-config script did not work when invoked from a
  56           source directory (STR #1673)

 106 CHANGES IN CUPS V1.2rc3
 107
 108         - The cups-lpd program always did reverse lookups on the

 127         - Added explicit notes to the cupsaddsmb man page
 128           explaining that the driver filenames are case-sensitive
 129           under UNIX and that they must be all lowercase (Windows
 130           2000) or all UPPERCASE (Windows 95/98/Me) to work (STR
 131           #1568)

 141           #1573)
 142         - cupsDoFileRequest() and cupsDoRequest() now work

 161           filters, but the filters needed the type data (STR #1558)
 162         - The scheduler didn't keep track of the status pipes
 163           properly, leading to a bad select() for multi-file jobs

 165         - The cupstestdsc program didn't validate the ordinal
 166           page number value for %%Page: comments.

 365         - The rastertodymo driver has been renamed to
 366           rastertolabel (a symlink is installed so that existing
 367           queues continue to work) and now also supports Zebra's
 368           CPCL language.
 369         - The lpstat command could show the wrong active job for
 370           a printer (STR #1301)

 439         - The parallel and USB backends now treat a "no space

 451         - The scheduler now verifies that a printer supports
 452           Letter or A4 media sizes before setting them as the

 457           is disconnected or turned off (STR #1267)
 458         - Added new httpGetHostname() function to CUPS API, and
 459           use it instead of gethostname() so that the web

 461           is not the FQDN (STR #1266)
 462         - The scheduler now stops printers if the backend for the

 465           to disable particular image file format support

 478         - Fixed a bug in the scheduler's startup signalling code
 479           which caused cupsd to send the SIGUSR1 signal to the
 480           init process instead of the original parent process
 481           (STR #1258)
 482         - Added new on-line help CGI to web interface to provide
 483           searchable help.
 484         - Devices are now tracked dynamically, with each query
 485           doing a new device scan.  This eliminates a previous
 486           startup delay caused by slow backends and allows new
 487           printers to be seen without restarting the server,
 488           however it limits the amount of device URI checking
 489           that can be done (basically now the scheduler only
 490           requires a URI with a method that is a listed backend)
 491         - Added new printer auto-detection, server configuration,
 492           and log file viewing to the administration web page.
 493         - Added new "set allowed users" web interface to set the
 494           list of allowed users for a printer or class.
 495         - The scheduler, command-line, and web interfaces now
 496           limit the list of printers and classes to those

 498         - cupsMarkOptions() now handles more non-standard
 499           duplexing options and choices (STR #915)
 500         - cups-lpd now honors remote banner requests with the
 501           "standard" banner whenever a printer does not have one
 502           defined (STR #1220)
 503         - The scheduler's denial-of-service checks did not work
 504           properly with IPv6 addresses (STR #1134)
 505         - The lp and lpr commands did not error out properly when
 506           they were unable to write to a temporary file (STR

 511           interface (STR #936)
 512         - The web interface now operates exclusively with the
 513           UTF-8 encoding, and sends the appropriate character set
 514           and header information to the web browser (STR #919,
 515           STR #1007)
 516         - Added a "set allowed users" interface to the web
 517           interface so that you can set the list of allowed or
 518           denied users/groups for a printer or class.
 519         - Disallow the "#" character in printer names, since it
 520           has special meaning in the shell, config files, and in
 521           URIs (STR #917, STR #1202)
 522         - Added a new application/x-csource MIME type, and
 523           support for it to the texttops filter so that you can
 524           pretty print plain text files without the C/C++
 525           keywords being highlighted.
 526         - The pdftops filter did not compile with GCC 4.0 (STR
 527           #1226)
 528         - The texttops filter did not highlight preprocessor
 529           directives followed by a tab properly.
 530         - HP PJL output now uses both JOB DISPLAY and RDYMSG
 531           commands to show the current job on the printer's
 532           display (STR #1218)
 533         - Local authentication certificates are now stored in
 534           /var/run/cups/certs by default instead of
 535           /etc/cups/certs (STR #1211)
 536         - Backends now use "&" to separate options in device
 537           URIs; "+" is still recognized but is deprecated (STR
 538           #842)
 539         - The USB backend no longer supports the usb:/dev/foo
 540           format on systems that support device ID queries.
 541         - Forced classification markings did not work when the
 542           job-sheets parameters were "none,none".
 543         - "lpstat -l -p" incorrectly showed all users as allowed,
 544           even if the queue was restricted to certain users (STR
 545           #801)
 546         - The scheduler now automatically detects SSL/TLS clients
 547           without using the SSLPort/SSLListen directives.

 549           encrypted connections.

 551           CUPS driver for Windows.
 552         - Fixed a signal-handling bug in httpRead() which
 553           ultimately caused the server to print multiple copies
 554           when it was busy (STR #1184)
 555         - The cupsFile API now uses the O_APPEND option when
 556           opening files in append mode (STR #990)
 557         - The md5.h header and md5_* functions are now officially
 558           private and have been renamed to avoid conflicts with
 559           other implementations with the same name.
 560         - The pdftops filter incorrectly embedded some Type1
 561           fonts (STR #1093)
 562         - The scheduler didn't detect a closed connection in the
 563           middle of an IPP request (STR #1153)
 564         - The scheduler could block trying to read the job status
 565           if there was input pending and the job was cancelled in
 566           the same input cycle (STR #1157)
 567         - The scheduler could crash when deleting a class due to
 568           infinite recursion.
 569         - Updated the Zebra ZPL label printer driver to use the
 570           run-length encoding and support more options.

 583           to remove printers as soon as they are deleted on the

 585           (STR #793)
 586         - The CUPS_SERVER and ServerName directives (client.conf

 595           URI, e.g. "encryption=required" (STR #732)
 596         - Added BrowseRemoteOptions directive to allow the
 597           administrator to add standard URI options to the
 598           remote printer URI, e.g. "encryption=required" (STR
 599           #732)
 600         - Now put "-I.." compiler option in front of all others
