  10         - The scheduler now reports the supported
  11           notify-recipient schemes based on the contents of the
  12           ServerBin/notifier directory.
  13         - Event notifications did not include the

  15           (STR #1747)
  16         - Allow/Deny addresses of the form "11.22.33.*" did not

  24         - Added a new default CUPS raster format (v3) which does
  25           not compress the raster stream in order to provide the
  26           same cupsRasterReadPixels() and cupsRasterWritePixels()
  27           performance as CUPS 1.1.x.
  28         - The cupsaddsmb man page listed the wrong files for the

  46         - 32/64-bit library installation was broken (STR #1741)
  47         - The USB backend now reports a "no such device" error
  48           when using the old filename-based USB URIs instead of
  49           the "success" error.
  50         - Increased the HTTP and IPP read timeouts to 10 seconds,

  71           value was missing (STR #1731)
  72         - Special cases for the "localhost" hostname did not

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

 133           XYZ or Lab color data.
 134         - The cups-config script did not work when invoked from a

 184
 185 CHANGES IN CUPS V1.2rc3
 186

 362
 363         - Updated the CUPS design description.
 364         - Added --enable-32bit and --enable-64bit configure
 365           options to allow building of separate 32/64-bit

 445           rastertolabel (a symlink is installed so that existing
 446           queues continue to work) and now also supports Zebra's
 447           CPCL language.
 448         - The lpstat command could show the wrong active job for
 449           a printer (STR #1301)
 450         - Fixed a potential crash problem in the scheduler when
 451           aborting a CGI program (STR #1290)

 484           #576)
 485         - Added support for the GCC position independent
 486           executable options (STR #1209)
 487         - Added new BrowseLocalProtocols and
 488           BrowseRemoteProtocols directives to cupsd.conf,
 489           allowing for different browse protocols for local and

 527         - All backends now abort on error when printing a job to
 528           a class - this allows the next printer in the class to

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

 536           is disconnected or turned off (STR #1267)
 537         - Added new httpGetHostname() function to CUPS API, and
 538           use it instead of gethostname() so that the web
 539           interface will work correctly on systems whose hostname
 540           is not the FQDN (STR #1266)
 541         - The scheduler now stops printers if the backend for the
 542           queue is missing on startup (STR #1265)
 543         - The configure script now supports "--disable-library"
 544           to disable particular image file format support
 545           libraries, even if they are available on the build
 546           system (STR #1248)
 547         - The IPP backend did not always report on the total
 548           number of pages that were printed (STR #1251)
 549         - The lpstat program could display garbage date and time
 550           values for locales whose date format exceeded 31

 555         - Added new cupsDir*() functions to CUPS API.
 556         - Printers can now be published individually for sharing.
 557         - Fixed a bug in the scheduler's startup signalling code
 558           which caused cupsd to send the SIGUSR1 signal to the
 559           init process instead of the original parent process
 560           (STR #1258)
 561         - Added new on-line help CGI to web interface to provide
 562           searchable help.
 563         - Devices are now tracked dynamically, with each query
 564           doing a new device scan.  This eliminates a previous
 565           startup delay caused by slow backends and allows new
 566           printers to be seen without restarting the server,
 567           however it limits the amount of device URI checking
 568           that can be done (basically now the scheduler only
 569           requires a URI with a method that is a listed backend)
 570         - Added new printer auto-detection, server configuration,
 571           and log file viewing to the administration web page.
 572         - Added new "set allowed users" web interface to set the
 573           list of allowed users for a printer or class.
 574         - The scheduler, command-line, and web interfaces now
 575           limit the list of printers and classes to those
 576           accessible by a user.
 577         - cupsMarkOptions() now handles more non-standard
 578           duplexing options and choices (STR #915)
 579         - cups-lpd now honors remote banner requests with the
 580           "standard" banner whenever a printer does not have one
 581           defined (STR #1220)
 582         - The scheduler's denial-of-service checks did not work
 583           properly with IPv6 addresses (STR #1134)
 584         - The lp and lpr commands did not error out properly when
 585           they were unable to write to a temporary file (STR
 586           #1129)
 587         - The pstops filter did not handle Adobe-specific
 588           comments in Windows NT driver output (STR #1085)
 589         - "lpstat -l -p" incorrectly reported the printer
 590           interface (STR #936)
 591         - The web interface now operates exclusively with the
 592           UTF-8 encoding, and sends the appropriate character set
 593           and header information to the web browser (STR #919,
 594           STR #1007)
 595         - Added a "set allowed users" interface to the web
 596           interface so that you can set the list of allowed or
 597           denied users/groups for a printer or class.
 598         - Disallow the "#" character in printer names, since it
 599           has special meaning in the shell, config files, and in
 600           URIs (STR #917, STR #1202)
 601         - Added a new application/x-csource MIME type, and
 602           support for it to the texttops filter so that you can
 603           pretty print plain text files without the C/C++
 604           keywords being highlighted.
 605         - The pdftops filter did not compile with GCC 4.0 (STR
 606           #1226)
 607         - The texttops filter did not highlight preprocessor
 608           directives followed by a tab properly.
 609         - HP PJL output now uses both JOB DISPLAY and RDYMSG
 610           commands to show the current job on the printer's
 611           display (STR #1218)
 612         - Local authentication certificates are now stored in
 613           /var/run/cups/certs by default instead of
 614           /etc/cups/certs (STR #1211)
 615         - Backends now use "&" to separate options in device
 616           URIs; "+" is still recognized but is deprecated (STR
 617           #842)
 618         - The USB backend no longer supports the usb:/dev/foo
 619           format on systems that support device ID queries.
 620         - Forced classification markings did not work when the
 621           job-sheets parameters were "none,none".
 622         - "lpstat -l -p" incorrectly showed all users as allowed,
 623           even if the queue was restricted to certain users (STR
 624           #801)
 625         - The scheduler now automatically detects SSL/TLS clients
 626           without using the SSLPort/SSLListen directives.
 627         - The CUPS API and scheduler no longer support SSLv2-
 628           encrypted connections.
 629         - Updated the cupsaddsmb utility to correctly export the
 630           CUPS driver for Windows.
 631         - Fixed a signal-handling bug in httpRead() which
 632           ultimately caused the server to print multiple copies
 633           when it was busy (STR #1184)
 634         - The cupsFile API now uses the O_APPEND option when
 635           opening files in append mode (STR #990)
 636         - The md5.h header and md5_* functions are now officially
 637           private and have been renamed to avoid conflicts with
 638           other implementations with the same name.
 639         - The pdftops filter incorrectly embedded some Type1
 640           fonts (STR #1093)
 641         - The scheduler didn't detect a closed connection in the
 642           middle of an IPP request (STR #1153)
 643         - The scheduler could block trying to read the job status

 661         - The CUPS browsing protocol now offers a "delete" bit
 662           to remove printers as soon as they are deleted on the
 663           server or as soon as the server shuts down gracefully
 664           (STR #793)
 665         - The CUPS_SERVER and ServerName directives (client.conf
 666           and ~/.cupsrc) may now contain names of the form

 674           URI, e.g. "encryption=required" (STR #732)
 675         - Added BrowseRemoteOptions directive to allow the
 676           administrator to add standard URI options to the
 677           remote printer URI, e.g. "encryption=required" (STR
 678           #732)
 679         - Now put "-I.." compiler option in front of all others
 680           to ensure that local CUPS headers are used before
 681           installed headers (STR #437)
 682         - New cupsLangPrintf() and cupsLangPuts() for localized
 683           interfaces.

 696           data for a job.
 697         - Backends and filters can now send and receive
 698           backchannel data over file descriptor 3.
 699         - Updated the raster stream format to support more
 700           user-defined attributes and to do compression of the
 701           page data.
