  10           default when displaying the /admin location (STR #1592)
  11         - The next job ID was not computed correctly if the job
  12           cache file got out of sync with the spool directory
  13           (STR #1582)
  14         - The PNG image handling code used deprecated functions

  24         - Fixed handling of job-hold-until (STR #1581)
  25         - Added explicit notes to the cupsaddsmb man page
  26           explaining that the driver filenames are case-sensitive
  27           under UNIX and that they must be all lowercase (Windows
  28           2000) or all UPPERCASE (Windows 95/98/Me) to work (STR
  29           #1568)

  59           filters, but the filters needed the type data (STR #1558)
  60         - The scheduler didn't keep track of the status pipes
  61           properly, leading to a bad select() for multi-file jobs
  62           (STR #1559)
  63         - The cupstestdsc program didn't validate the ordinal
  64           page number value for %%Page: comments.

 327           #281)
 328         - The pdftops filter produced large output when rendering

 330         - The pdftops filter now minimizes print processing of
 331           PDF files when using the page-ranges option (STR #273)
 332         - Updated pdftops filter to Xpdf 3.01.
 333         - Added new cupsBackchannelRead() and
 334           cupsBackchannelWrite() functions, as well as
 335           backchannel support to the parallel, serial, socket,
 336           and USB backends (STR #1252)
 337         - The parallel and USB backends now treat a "no space

 346         - All backends now abort on error when printing a job to
 347           a class - this allows the next printer in the class to
 348           print the job (STR #1084)
 349         - The scheduler now verifies that a printer supports
 350           Letter or A4 media sizes before setting them as the
 351           initial default (STR #1250)

 354         - The USB backend now retries printing when the printer
 355           is disconnected or turned off (STR #1267)
 356         - Added new httpGetHostname() function to CUPS API, and
 357           use it instead of gethostname() so that the web
 358           interface will work correctly on systems whose hostname
 359           is not the FQDN (STR #1266)
 360         - The scheduler now stops printers if the backend for the
 361           queue is missing on startup (STR #1265)
 362         - The configure script now supports "--disable-library"
 363           to disable particular image file format support
 364           libraries, even if they are available on the build
 365           system (STR #1248)
 366         - The IPP backend did not always report on the total
 367           number of pages that were printed (STR #1251)
 368         - The lpstat program could display garbage date and time
 369           values for locales whose date format exceeded 31
 370           characters (STR #1263)
 371         - The cupstestppd program would segfault when testing

 374         - Added new cupsDir*() functions to CUPS API.
 375         - Printers can now be published individually for sharing.
 376         - Fixed a bug in the scheduler's startup signalling code
 377           which caused cupsd to send the SIGUSR1 signal to the
 378           init process instead of the original parent process
 379           (STR #1258)
 380         - Added new on-line help CGI to web interface to provide
 381           searchable help.
 382         - Devices are now tracked dynamically, with each query
 383           doing a new device scan.  This eliminates a previous
 384           startup delay caused by slow backends and allows new
 385           printers to be seen without restarting the server,
 386           however it limits the amount of device URI checking
 387           that can be done (basically now the scheduler only
 388           requires a URI with a method that is a listed backend)
 389         - Added new printer auto-detection, server configuration,
 390           and log file viewing to the administration web page.
 391         - Added new "set allowed users" web interface to set the
 392           list of allowed users for a printer or class.
 393         - The scheduler, command-line, and web interfaces now
 394           limit the list of printers and classes to those
 395           accessible by a user.
 396         - cupsMarkOptions() now handles more non-standard
 397           duplexing options and choices (STR #915)
 398         - cups-lpd now honors remote banner requests with the
 399           "standard" banner whenever a printer does not have one
 400           defined (STR #1220)
 401         - The scheduler's denial-of-service checks did not work
 402           properly with IPv6 addresses (STR #1134)
 403         - The lp and lpr commands did not error out properly when
 404           they were unable to write to a temporary file (STR
 405           #1129)

 409           interface (STR #936)
 410         - The web interface now operates exclusively with the
 411           UTF-8 encoding, and sends the appropriate character set
 412           and header information to the web browser (STR #919,
 413           STR #1007)
 414         - Added a "set allowed users" interface to the web
 415           interface so that you can set the list of allowed or
 416           denied users/groups for a printer or class.
 417         - Disallow the "#" character in printer names, since it
 418           has special meaning in the shell, config files, and in
 419           URIs (STR #917, STR #1202)
 420         - Added a new application/x-csource MIME type, and
 421           support for it to the texttops filter so that you can
 422           pretty print plain text files without the C/C++
 423           keywords being highlighted.
 424         - The pdftops filter did not compile with GCC 4.0 (STR
 425           #1226)
 426         - The texttops filter did not highlight preprocessor
 427           directives followed by a tab properly.
 428         - HP PJL output now uses both JOB DISPLAY and RDYMSG

 430           display (STR #1218)
 431         - Local authentication certificates are now stored in
 432           /var/run/cups/certs by default instead of
 433           /etc/cups/certs (STR #1211)
 434         - Backends now use "&" to separate options in device
 435           URIs; "+" is still recognized but is deprecated (STR
 436           #842)
 437         - The USB backend no longer supports the usb:/dev/foo
 438           format on systems that support device ID queries.
 439         - Forced classification markings did not work when the
 440           job-sheets parameters were "none,none".
 441         - "lpstat -l -p" incorrectly showed all users as allowed,
 442           even if the queue was restricted to certain users (STR
 443           #801)
 444         - The scheduler now automatically detects SSL/TLS clients
 445           without using the SSLPort/SSLListen directives.
 446         - The CUPS API and scheduler no longer support SSLv2-
 447           encrypted connections.
 448         - Updated the cupsaddsmb utility to correctly export the
 449           CUPS driver for Windows.
 450         - Fixed a signal-handling bug in httpRead() which
 451           ultimately caused the server to print multiple copies
 452           when it was busy (STR #1184)
 453         - The cupsFile API now uses the O_APPEND option when
 454           opening files in append mode (STR #990)
 455         - The md5.h header and md5_* functions are now officially
 456           private and have been renamed to avoid conflicts with
 457           other implementations with the same name.
 458         - The pdftops filter incorrectly embedded some Type1
 459           fonts (STR #1093)
 460         - The scheduler didn't detect a closed connection in the
 461           middle of an IPP request (STR #1153)
 462         - The scheduler could block trying to read the job status
 463           if there was input pending and the job was cancelled in
 464           the same input cycle (STR #1157)
 465         - The scheduler could crash when deleting a class due to
 466           infinite recursion.
 467         - Updated the Zebra ZPL label printer driver to use the
 468           run-length encoding and support more options.
 469         - Updated serial backend to scan for /dev/ttyC* as well
 470           as /dev/ttyc* for Cyclades serial ports (STR #1049)
 471         - The scheduler could hang reading the job status under
 472           certain circumstances (STR #1068)

 479           PostScript commands in a PPD file.
 480         - The CUPS browsing protocol now offers a "delete" bit
 481           to remove printers as soon as they are deleted on the
 482           server or as soon as the server shuts down gracefully
 483           (STR #793)
 484         - The CUPS_SERVER and ServerName directives (client.conf
 485           and ~/.cupsrc) may now contain names of the form

 492           administrator to add printer URI options to the browse
 493           URI, e.g. "encryption=required" (STR #732)
 494         - Added BrowseRemoteOptions directive to allow the
 495           administrator to add standard URI options to the
 496           remote printer URI, e.g. "encryption=required" (STR
 497           #732)
 498         - Now put "-I.." compiler option in front of all others
 499           to ensure that local CUPS headers are used before
 500           installed headers (STR #437)
