        - The cups-lpd mini-daemon did not work on Mac OS X server.
        - Added httpGetAuthString() and httpSetAuthString() APIs to get
          and set the current (cached) authorization string to use for
          HTTP requests.
        - Updated the default cupsd.conf policy to list the
          "administrative" operations separately from the "printer
          control" operations so that it is easier to define a
          group of users that are "printer operators".
        - The web interface now pulls the default cupsd.conf file
          from cupsd.conf.default in the CUPS config directory.
        - Added a help file for using Kerberos with CUPS.
        - The scheduler now strips the "@KDC" portion of Kerberos
          usernames since those usernames typically do not appear in
          the group membership lists used by CUPS.
        - cupsMarkOptions() could (incorrectly) leave multiple option
          choices marked.
        - Backends could (incorrectly) run as root during discovery
          (STR #2454)
        - Avahi is now supported for DNS-SD (Bonjour) printer sharing
          (STR #2455)
        - The default cupsd.conf file had typos and old operation names
          (STR #2450)
        - The scheduler now erases authentication cache files using the
          7-pass US DoD algorithm.
        - Delegated Kerberos credentials (proxy authentication) did not
          work.
        - The filter makefile did not optimize the libcupsimage.2.dylib
          with a sectorder file.
        - The IPP backend incorrectly wrote an empty printer message
          when processing the "none" state reason.
        - The USB backend could deadlock on Mac OS X while performing
          a side-channel command.
        - The scheduler did not prevent remote queues from being
          shared/published.
        - The scheduler did not remove the temporary request file on
          authentication errors.
        - ppdLocalizeIPPReason() did not handle "scheme:" schemes or
          "file" URLs.
        - ppdLocalizeIPPReason() was not exported on Mac OS X.


CHANGES IN CUPS V1.3b1

        - Copyright updates - CUPS is now owned by Apple Inc.
        - Documentation updates (STR #1775, STR #2027, STR #2130,
          STR #2131, STR #2263, STR #2356, STR #2397)
        - Added new cupsfilter utility (STR #1734)
        - Added new job-printer-state-message and
          job-printer-state-reasons attributes to jobs (STR #2418)
        - Added LDAP+SSL support (STR #1967)
        - CUPS now supports authentication via peer credentials
          over domain sockets (STR #2242, STR #2277)
        - The CUPS sample driver PPDs are now generated by the PPD
          compiler and include all of the localized languages by
          default (STR #2164)
        - You can now specify "AuthType Default" in the cupsd.conf
          file to use the default authentication defined by the
          DefaultAuthType directive.
        - The SNMP backend no longer adds a default Address line
          when none is specified in the snmp.conf file; this allows
          the backend to be easily disabled as needed (STR #2434)
        - Added a new cupsctl command for doing basic changes to
          the cupsd.conf file (STR #1777)
        - Added a new ppdLocalizeIPPReason() function to get the
          localized text/URI for a given IPP reason keyword for a
          driver.
        - Removed the deskjet2.ppd driver, as it only worked with
          a very small subset of HP DeskJet printers and was
          confusing to users.  The rastertohp driver still
          supports the deskjet2.ppd options for existing queues.
        - The scheduler did not add a trailing banner page if a
          client did not specify the last document in a job (STR
          #1711)
        - The scheduler did not report Bonjour shared printers as
          remote printers (STR #2384)
        - Added new -R and -W options to the cupstestppd program
          for greater control over the testing of PPDs.
        - Added a new cupsGetServerPPD() function for getting
          an available PPD from the server (STR #2334)
        - Added a new cupsDoIORequest() function for reading
          and writing files via IPP requests (STR #2334)
        - Added a new CUPS_GET_PPD operation for getting an
          available PPD file on the server (STR #2334) 
        - CUPS_GET_PPDS now reports multiple ppd-product values
          based on the PPD ModelName and Product strings (STR
          #2334, STR #2383)
        - CUPS_GET_PPDS now reports the PSVersion attributes
          from a PPD file in the ppd-psversion attribute
          (STR #2334)
        - CUPS_GET_PPDS now reports the cupsModelNumber attribute
          from a PPD file in the ppd-model-number attribute (STR
          #2383)
        - CUPS_GET_PPDS now reports a driver type string in the
          ppd-type attribute based on the cupsFax and cupsFilter
          attributes in a PPD file (STR #2383)
        - Added a new printer attribute called "cups-version"
          which reports the version of CUPS that is running
          (STR #2240)
        - backendRunLoop() now aborts immediately on SIGTERM
          if no data has been written yet (STR #2103)
        - Due to poor IPP support from the vendors, the SNMP
          backend no longer tries IPP connections; instead,
          it now uses a lookup file with fallback to port 9100
          (socket://address) and 515 (lpd://address) printing
          (STR #2035, STR #2354) 
        - The scheduler now recreates the CUPS log directory as
          needed (STR #2353)
        - cupsLangDefault() now maps new-style Apple locale names
          to the traditional ll_CC form (STR #2357)
        - Add new cupsArrayNew2() API to support hashed lookups
          of array elements (STR #2358)
        - ppdConflicts() optimizations (STR #2358)

          icons, profiles, and dialog extensions (STR #2326)
        - The web interface no longer lists new printers on the
          main administration page.  Instead, a new "List Available
          Printers" button is provided that shows a separate page
          with the list of printers.
        - The web interface now supports setting the banner and
          policy options on raw printers and classes (STR #2238)
        - The socket backend now reads any pending back-channel
          data before shutting down the socket (STR #2325)
        - Added a new ErrorPolicy directive in the cupsd.conf
          file (STR #1871)
        - Printers that use JCL options are now exported to Samba
          correctly (STR #1985)
        - The IPP backend now relays printer-state-message values
          from the server to the client (STR #2109)
        - Added support for the PWG printer-alert and
          printer-alert-description attributes (STR #2088)
        - Added support for LPD "stream" mode (STR #2036)
        - The scheduler now reports the PostScript product string
          from PPD files in CUPS-Get-PPDs responses (STR #1900)

          for creating web interface buttons (STR #2231)
        - Added support for DNS-SD (aka "Bonjour") printer sharing
          (STR #1171)
        - Job operations (cancel, hold, release, etc.) from the
          web interface now return back to the original page (STR
          #2239)
        - The classes or printers list is now shown after a
          successful deletion from the web interface (STR #1999)
        - The default configuration now allows browse packets from

          the "printer-defaults" attribute group is requested (STR
          #1923)
        - Added support for Linux "relro" linker option (STR #1614)
        - CUPS now validates the number-up option value (STR #1329)
        - The on-line help now provides better search capabilities
          (STR #1701)
        - The web interface "Add This Printer" button now allows you

        - Added support for Mac OS X authorization services
          (STR #2206)
        - Added support for driver-specific pre-filters (STR #2108)
        - Added a new side-channel API for drivers and backends
          for basic device control and information queries (STR
          #1898)
        - The scheduler now uses poll(), epoll(), or /dev/kqueue
          instead of select() when possible (STR #1261)

          strings (STR #1969)
        - Moved the definition of the (private) _http_s structure
          to http-private.h; code that directly accesses the
          http_t members will no longer compile!

          attribute on a per-printer basis.
        - Added support for IntelliBar label printers.
