 336         - Fixed the localization instructions and German template for
 337           the "Find New Printers" button (STR #2478)
 338         - The web interface did not work with the Chinese localization
 339           (STR #2477)
 340         - The web interface home page did not work for languages that
 341           were only partially localized (STR #2472)
 342         - Updated the Spanish web interface localization (STR #2473)
 343         - ppdLocalize() did not work for country-specific localizations.

 346 CHANGES IN CUPS V1.3.0
 347
 348         - The scheduler did not handle out-of-file conditions
 349           gracefully when accepting new connections, leading to
 350           heavy CPU usage.
 351         - The scheduler did not detect ServerBin misconfigurations
 352           (STR #2470)
 353         - "AuthType Default" did not work as expected when the
 354           "DefaultAuthType foo" line appeared after it in the
 355           cupsd.conf file.
 356         - The on-line help did not describe many common printing
 357           options (STR #1846)
 358         - The IPP backend did not return the "auth required" status
 359           when printing to a Kerberos-protected queue.
 360         - The scheduler was not looking in the correct directories
 361           for LSB PPD files (STR #2464)
 362         - Changed references to ESP Ghostscript to GPL Ghostscript
 363           (STR #2463)
 364         - The PostScript filter did not cleanly terminate when
 365           the job was canceled or stopped.
 366         - Fixed generation of Kerberos credentials for remote
 367           printing.  Note that this requires a recent version of
 368           MIT Kerberos with a working krb5_cc_new_unique()
 369           function or Heimdal Kerberos.
 370         - Added Portuguese and updated Italian message catalogs.
 371
 372
 373 CHANGES IN CUPS V1.3rc2
 374
 375         - Added more range checking to the pdftops filter.
 376         - The scheduler would crash if a remote IPP queue was stopped
 377           (STR #2460)
 378         - The scheduler did not allow "DefaultAuthType None".
 379
 380
 381 CHANGES IN CUPS V1.3rc1
 382
 383         - Updated the German localization (STR #2443)
 384         - cupsAdminGetServerSettings() did not handle </Foo> properly.
 385         - When lprm and cancel are run with no job ID, they now will
 386           cancel the first stopped job if no pending or processing
 387           jobs are left in the queue.
 388         - The scheduler now logs successful print jobs, filter
 389           failures, and the job file types at the default log
 390           level (STR #2458)
 391         - The scheduler now logs the usernames it is using for
 392           authorization at LogLevel debug instead of debug2 (STR #2448)
 393         - Added Intellitech Intellibar and Zebra CPCL PPDs to the list
 394           of installed PPDs.
 395         - Added 6" and 8" wide label sizes for the Zebra ZPL Label
 396           Printer driver (STR #2442)
 397         - The cupsaddsmb program and web interface now support
 398           exporting of 64-bit Windows drivers, when available
 399           (STR #2439)
 400         - Moving a job that was printing did not stop the job on the
 401           original printer (STR #2262)
 402         - The cups-lpd mini-daemon did not work on Mac OS X server.
 403         - Added httpGetAuthString() and httpSetAuthString() APIs to get
 404           and set the current (cached) authorization string to use for
 405           HTTP requests.
 406         - Updated the default cupsd.conf policy to list the
 407           "administrative" operations separately from the "printer
 408           control" operations so that it is easier to define a
 409           group of users that are "printer operators".
 410         - The web interface now pulls the default cupsd.conf file
 411           from cupsd.conf.default in the CUPS config directory.
 412         - Added a help file for using Kerberos with CUPS.
 413         - The scheduler now strips the "@KDC" portion of Kerberos
 414           usernames since those usernames typically do not appear in
 415           the group membership lists used by CUPS.
 416         - cupsMarkOptions() could (incorrectly) leave multiple option
 417           choices marked.

 419           (STR #2454)
 420         - Avahi is now supported for DNS-SD (Bonjour) printer sharing
 421           (STR #2455)
 422         - The default cupsd.conf file had typos and old operation names
 423           (STR #2450)
 424         - The scheduler now erases authentication cache files using the
 425           7-pass US DoD algorithm.
 426         - Delegated Kerberos credentials (proxy authentication) did not
 427           work.
 428         - The filter makefile did not optimize the libcupsimage.2.dylib
 429           with a sectorder file.
 430         - The IPP backend incorrectly wrote an empty printer message
 431           when processing the "none" state reason.
 432         - The USB backend could deadlock on Mac OS X while performing
 433           a side-channel command.
 434         - The scheduler did not prevent remote queues from being
 435           shared/published.
 436         - The scheduler did not remove the temporary request file on
 437           authentication errors.

 441
 442
 443 CHANGES IN CUPS V1.3b1
 444
 445         - Copyright updates - CUPS is now owned by Apple Inc.
 446         - Documentation updates (STR #1775, STR #2027, STR #2130,
 447           STR #2131, STR #2263, STR #2356, STR #2397)
 448         - Added new cupsfilter utility (STR #1734)
 449         - Added new job-printer-state-message and
 450           job-printer-state-reasons attributes to jobs (STR #2418)
 451         - Added LDAP+SSL support (STR #1967)
 452         - CUPS now supports authentication via peer credentials
 453           over domain sockets (STR #2242, STR #2277)
 454         - The CUPS sample driver PPDs are now generated by the PPD
 455           compiler and include all of the localized languages by
 456           default (STR #2164)
 457         - You can now specify "AuthType Default" in the cupsd.conf
 458           file to use the default authentication defined by the
 459           DefaultAuthType directive.
 460         - The SNMP backend no longer adds a default Address line
 461           when none is specified in the snmp.conf file; this allows
 462           the backend to be easily disabled as needed (STR #2434)
 463         - Added a new cupsctl command for doing basic changes to
 464           the cupsd.conf file (STR #1777)
 465         - Added a new ppdLocalizeIPPReason() function to get the
 466           localized text/URI for a given IPP reason keyword for a
 467           driver.
 468         - Removed the deskjet2.ppd driver, as it only worked with
 469           a very small subset of HP DeskJet printers and was
 470           confusing to users.  The rastertohp driver still
 471           supports the deskjet2.ppd options for existing queues.
 472         - The scheduler did not add a trailing banner page if a
 473           client did not specify the last document in a job (STR
 474           #1711)
 475         - The scheduler did not report Bonjour shared printers as
 476           remote printers (STR #2384)
 477         - Added new -R and -W options to the cupstestppd program
 478           for greater control over the testing of PPDs.
 479         - Added a new cupsGetServerPPD() function for getting
 480           an available PPD from the server (STR #2334)
 481         - Added a new cupsDoIORequest() function for reading
 482           and writing files via IPP requests (STR #2334)
 483         - Added a new CUPS_GET_PPD operation for getting an
 484           available PPD file on the server (STR #2334)
 485         - CUPS_GET_PPDS now reports multiple ppd-product values
 486           based on the PPD ModelName and Product strings (STR
 487           #2334, STR #2383)
 488         - CUPS_GET_PPDS now reports the PSVersion attributes
 489           from a PPD file in the ppd-psversion attribute
 490           (STR #2334)
 491         - CUPS_GET_PPDS now reports the cupsModelNumber attribute
 492           from a PPD file in the ppd-model-number attribute (STR
 493           #2383)
 494         - CUPS_GET_PPDS now reports a driver type string in the
 495           ppd-type attribute based on the cupsFax and cupsFilter
 496           attributes in a PPD file (STR #2383)
 497         - Added a new printer attribute called "cups-version"
 498           which reports the version of CUPS that is running
 499           (STR #2240)
 500         - backendRunLoop() now aborts immediately on SIGTERM
 501           if no data has been written yet (STR #2103)
 502         - Due to poor IPP support from the vendors, the SNMP
 503           backend no longer tries IPP connections; instead,
 504           it now uses a lookup file with fallback to port 9100
 505           (socket://address) and 515 (lpd://address) printing
 506           (STR #2035, STR #2354)
 507         - The scheduler now recreates the CUPS log directory as
 508           needed (STR #2353)
 509         - cupsLangDefault() now maps new-style Apple locale names
 510           to the traditional ll_CC form (STR #2357)
 511         - Add new cupsArrayNew2() API to support hashed lookups
 512           of array elements (STR #2358)
 513         - ppdConflicts() optimizations (STR #2358)
 514         - The cupstestppd program now tests for existing filters,
 515           icons, profiles, and dialog extensions (STR #2326)
 516         - The web interface no longer lists new printers on the
 517           main administration page.  Instead, a new "List Available
 518           Printers" button is provided that shows a separate page
 519           with the list of printers.
 520         - The web interface now supports setting the banner and
 521           policy options on raw printers and classes (STR #2238)
 522         - The socket backend now reads any pending back-channel
 523           data before shutting down the socket (STR #2325)
 524         - Added a new ErrorPolicy directive in the cupsd.conf
 525           file (STR #1871)

 531           printer-alert-description attributes (STR #2088)
 532         - Added support for LPD "stream" mode (STR #2036)
 533         - The scheduler now reports the PostScript product string
 534           from PPD files in CUPS-Get-PPDs responses (STR #1900)
 535         - Raw printing with queues pointing to the file pseudo-
 536           device and multiple files and/or banners now works (STR
 537           #1933)
 538         - Added new public cupsAdminGetServerSettings() and
 539           cupsAdminSetServerSettings() APIs.
 540         - Added new "makebuttons" script in the "tools" directory
 541           for creating web interface buttons (STR #2231)
 542         - Added support for DNS-SD (aka "Bonjour") printer sharing
 543           (STR #1171)
 544         - Job operations (cancel, hold, release, etc.) from the
 545           web interface now return back to the original page (STR
 546           #2239)
 547         - The classes or printers list is now shown after a
 548           successful deletion from the web interface (STR #1999)
 549         - The default configuration now allows browse packets from
 550           any address (STR #2008)
 551         - The web interface now provides an "allow printing from the
 552           Internet" check box (STR #1897)
 553         - The notify-events-default and
 554           notify-lease-duration-default attributes can now be set
 555           (STR #1671)

 557           the "printer-defaults" attribute group is requested (STR
 558           #1923)
 559         - Added support for Linux "relro" linker option (STR #1614)
 560         - CUPS now validates the number-up option value (STR #1329)

 572         - The scheduler now uses poll(), epoll(), or /dev/kqueue
 573           instead of select() when possible (STR #1261)
 574         - Added new cupsArrayGetIndex() and cupsArrayGetInsert()
 575           functions to get the current index and insertion
 576           positions of an array.
 577         - Added a new --with-max-copies configure option (STR
 578           #2090)
 579         - Added new cupsRemoveDest() and cupsSetDefaultDest()
 580           functions.
