 342         - When lprm and cancel are run with no job ID, they now will
 343           cancel the first stopped job if no pending or processing
 344           jobs are left in the queue.
 345         - The scheduler now logs successful print jobs, filter
 346           failures, and the job file types at the default log
 347           level (STR #2458)
 348         - The scheduler now logs the usernames it is using for
 349           authorization at LogLevel debug instead of debug2 (STR #2448)
 350         - Added Intellitech Intellibar and Zebra CPCL PPDs to the list
 351           of installed PPDs.
 352         - Added 6" and 8" wide label sizes for the Zebra ZPL Label
 353           Printer driver (STR #2442)

 355           exporting of 64-bit Windows drivers, when available
 356           (STR #2439)
 357         - Moving a job that was printing did not stop the job on the
 358           original printer (STR #2262)
 359         - The cups-lpd mini-daemon did not work on Mac OS X server.
 360         - Added httpGetAuthString() and httpSetAuthString() APIs to get
 361           and set the current (cached) authorization string to use for
 362           HTTP requests.
 363         - Updated the default cupsd.conf policy to list the
 364           "administrative" operations separately from the "printer
 365           control" operations so that it is easier to define a
 366           group of users that are "printer operators".
 367         - The web interface now pulls the default cupsd.conf file
 368           from cupsd.conf.default in the CUPS config directory.
 369         - Added a help file for using Kerberos with CUPS.
 370         - The scheduler now strips the "@KDC" portion of Kerberos
 371           usernames since those usernames typically do not appear in
 372           the group membership lists used by CUPS.
 373         - cupsMarkOptions() could (incorrectly) leave multiple option
 374           choices marked.

 378           (STR #2455)
 379         - The default cupsd.conf file had typos and old operation names
 380           (STR #2450)
 381         - The scheduler now erases authentication cache files using the
 382           7-pass US DoD algorithm.
 383         - Delegated Kerberos credentials (proxy authentication) did not
 384           work.
 385         - The filter makefile did not optimize the libcupsimage.2.dylib
 386           with a sectorder file.
 387         - The IPP backend incorrectly wrote an empty printer message
 388           when processing the "none" state reason.
 389         - The USB backend could deadlock on Mac OS X while performing
 390           a side-channel command.
 391         - The scheduler did not prevent remote queues from being
 392           shared/published.

 400 CHANGES IN CUPS V1.3b1
 401
 402         - Copyright updates - CUPS is now owned by Apple Inc.
 403         - Documentation updates (STR #1775, STR #2027, STR #2130,
 404           STR #2131, STR #2263, STR #2356, STR #2397)
 405         - Added new cupsfilter utility (STR #1734)
 406         - Added new job-printer-state-message and
 407           job-printer-state-reasons attributes to jobs (STR #2418)
 408         - Added LDAP+SSL support (STR #1967)
 409         - CUPS now supports authentication via peer credentials
 410           over domain sockets (STR #2242, STR #2277)
 411         - The CUPS sample driver PPDs are now generated by the PPD
 412           compiler and include all of the localized languages by
 413           default (STR #2164)
 414         - You can now specify "AuthType Default" in the cupsd.conf
 415           file to use the default authentication defined by the
 416           DefaultAuthType directive.
 417         - The SNMP backend no longer adds a default Address line
 418           when none is specified in the snmp.conf file; this allows
 419           the backend to be easily disabled as needed (STR #2434)
 420         - Added a new cupsctl command for doing basic changes to
 421           the cupsd.conf file (STR #1777)
 422         - Added a new ppdLocalizeIPPReason() function to get the
 423           localized text/URI for a given IPP reason keyword for a
 424           driver.
 425         - Removed the deskjet2.ppd driver, as it only worked with
 426           a very small subset of HP DeskJet printers and was
 427           confusing to users.  The rastertohp driver still
 428           supports the deskjet2.ppd options for existing queues.
 429         - The scheduler did not add a trailing banner page if a
 430           client did not specify the last document in a job (STR
 431           #1711)
 432         - The scheduler did not report Bonjour shared printers as
 433           remote printers (STR #2384)
 434         - Added new -R and -W options to the cupstestppd program
 435           for greater control over the testing of PPDs.
 436         - Added a new cupsGetServerPPD() function for getting
 437           an available PPD from the server (STR #2334)
 438         - Added a new cupsDoIORequest() function for reading
 439           and writing files via IPP requests (STR #2334)
 440         - Added a new CUPS_GET_PPD operation for getting an
 441           available PPD file on the server (STR #2334)
 442         - CUPS_GET_PPDS now reports multiple ppd-product values
 443           based on the PPD ModelName and Product strings (STR
 444           #2334, STR #2383)
 445         - CUPS_GET_PPDS now reports the PSVersion attributes
 446           from a PPD file in the ppd-psversion attribute
 447           (STR #2334)
 448         - CUPS_GET_PPDS now reports the cupsModelNumber attribute
 449           from a PPD file in the ppd-model-number attribute (STR
 450           #2383)
 451         - CUPS_GET_PPDS now reports a driver type string in the
 452           ppd-type attribute based on the cupsFax and cupsFilter
 453           attributes in a PPD file (STR #2383)
 454         - Added a new printer attribute called "cups-version"
 455           which reports the version of CUPS that is running
 456           (STR #2240)
 457         - backendRunLoop() now aborts immediately on SIGTERM
 458           if no data has been written yet (STR #2103)
 459         - Due to poor IPP support from the vendors, the SNMP
 460           backend no longer tries IPP connections; instead,
 461           it now uses a lookup file with fallback to port 9100
 462           (socket://address) and 515 (lpd://address) printing
 463           (STR #2035, STR #2354)
 464         - The scheduler now recreates the CUPS log directory as
 465           needed (STR #2353)
 466         - cupsLangDefault() now maps new-style Apple locale names
 467           to the traditional ll_CC form (STR #2357)
 468         - Add new cupsArrayNew2() API to support hashed lookups
 469           of array elements (STR #2358)
 470         - ppdConflicts() optimizations (STR #2358)
 471         - The cupstestppd program now tests for existing filters,
 472           icons, profiles, and dialog extensions (STR #2326)
 473         - The web interface no longer lists new printers on the
 474           main administration page.  Instead, a new "List Available
 475           Printers" button is provided that shows a separate page
 476           with the list of printers.
 477         - The web interface now supports setting the banner and
 478           policy options on raw printers and classes (STR #2238)
 479         - The socket backend now reads any pending back-channel
 480           data before shutting down the socket (STR #2325)
 481         - Added a new ErrorPolicy directive in the cupsd.conf
 482           file (STR #1871)

 488           printer-alert-description attributes (STR #2088)
 489         - Added support for LPD "stream" mode (STR #2036)
 490         - The scheduler now reports the PostScript product string
 491           from PPD files in CUPS-Get-PPDs responses (STR #1900)
 492         - Raw printing with queues pointing to the file pseudo-
 493           device and multiple files and/or banners now works (STR
 494           #1933)
 495         - Added new public cupsAdminGetServerSettings() and
 496           cupsAdminSetServerSettings() APIs.
 497         - Added new "makebuttons" script in the "tools" directory
 498           for creating web interface buttons (STR #2231)
 499         - Added support for DNS-SD (aka "Bonjour") printer sharing
 500           (STR #1171)
 501         - Job operations (cancel, hold, release, etc.) from the

 503           #2239)
 504         - The classes or printers list is now shown after a
 505           successful deletion from the web interface (STR #1999)
 506         - The default configuration now allows browse packets from
 507           any address (STR #2008)
 508         - The web interface now provides an "allow printing from the
 509           Internet" check box (STR #1897)
 510         - The notify-events-default and
 511           notify-lease-duration-default attributes can now be set
 512           (STR #1671)

 514           the "printer-defaults" attribute group is requested (STR
 515           #1923)
 516         - Added support for Linux "relro" linker option (STR #1614)
 517         - CUPS now validates the number-up option value (STR #1329)

 529         - The scheduler now uses poll(), epoll(), or /dev/kqueue
 530           instead of select() when possible (STR #1261)
 531         - Added new cupsArrayGetIndex() and cupsArrayGetInsert()
 532           functions to get the current index and insertion
 533           positions of an array.
 534         - Added a new --with-max-copies configure option (STR
 535           #2090)
