   8           for Asian text (STR #1819)
   9         - The lpoptions -o and -r options did not work unless you
  10           specified a printer.
  11         - The lpoptions command incorrectly allowed users to set
  12           printer attributes like printer-type (STR #1791)
  13         - httpWait() did not flush the write buffer, causing "bad
  14           request" errors when communicating with CUPS 1.1.x
  15           servers (STR #1717)
  16         - Polling did not sanitize the printer description,
  17           location, or make and model strings like broadcasts
  18           did.
  19         - Polled printers did not show the server's default
  20           job-sheets option value.
  21         - The Samba password prompt was not properly localized
  22           (STR #1814)

  25           automatically when using OpenSSL and CDSA for
  26           encryption, just as for GNU TLS.

  29         - The scheduler now forces BrowseTimeout to be at least
  30           twice the BrowseInterval value and non-zero to avoid
  31           common configuration errors.
  32         - The scheduler incorrectly returned printer URIs of the
  33           form "ipp://server/printers/classname" for classes (STR

  38         - Added a mailto.conf man page and help page (STR #1754)
  39         - The parallel and USB backends no longer wait for the
  40           printer to go on-line - this caused problems with

  42           standard (STR #1738)
  43         - The scheduler could crash on a reload when implicit

  66         - The pdftops filter incorrectly embedded a "produced by"
  67           comment, causing PDF printing not to work on some
  68           operating systems (STR #1801)
  69         - Sending raw jobs from a client system could cause the
  70           client's scheduler to eventually crash (STR #1786)

  72           to accepting a new subscription request.
  73         - The scheduler now reports the supported
  74           notify-recipient schemes based on the contents of the
  75           ServerBin/notifier directory.
  76         - Event notifications did not include the

  87         - Added a new default CUPS raster format (v3) which does
  88           not compress the raster stream in order to provide the
  89           same cupsRasterReadPixels() and cupsRasterWritePixels()
  90           performance as CUPS 1.1.x.
  91         - The cupsaddsmb man page listed the wrong files for the

 101         - The cupsd.conf man page didn't describe the Listen
 102           domain socket syntax (STR #1753)

 109         - 32/64-bit library installation was broken (STR #1741)
 110         - The USB backend now reports a "no such device" error
 111           when using the old filename-based USB URIs instead of
 112           the "success" error.
 113         - Increased the HTTP and IPP read timeouts to 10 seconds,
 114           as 1 second was too short on congested networks (STR
 115           #1719)
 116         - The SNMP backend now uses the device description over
 117           the printer-make-and-model attribute when the attribute

 119         - Fixed another file descriptor leak when printing raw
 120           files (STR #1736)

 134           value was missing (STR #1731)
 135         - Special cases for the "localhost" hostname did not
 136           work, causing printing to not work when the /etc/hosts
 137           file did not contain a localhost entry (STR #1723)
 138         - Updated the Spanish translation (STR #1720, STR #1770)

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

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

 264
 265
 266 CHANGES IN CUPS V1.2rc3
 267
 268         - The cups-lpd program always did reverse lookups on the

 287         - Added explicit notes to the cupsaddsmb man page
 288           explaining that the driver filenames are case-sensitive
 289           under UNIX and that they must be all lowercase (Windows
 290           2000) or all UPPERCASE (Windows 95/98/Me) to work (STR
 291           #1568)

 643           searchable help.
 644         - Devices are now tracked dynamically, with each query
 645           doing a new device scan.  This eliminates a previous
 646           startup delay caused by slow backends and allows new
 647           printers to be seen without restarting the server,
 648           however it limits the amount of device URI checking
 649           that can be done (basically now the scheduler only
 650           requires a URI with a method that is a listed backend)
 651         - Added new printer auto-detection, server configuration,
 652           and log file viewing to the administration web page.
 653         - Added new "set allowed users" web interface to set the
 654           list of allowed users for a printer or class.
 655         - The scheduler, command-line, and web interfaces now
 656           limit the list of printers and classes to those
 657           accessible by a user.
 658         - cupsMarkOptions() now handles more non-standard
 659           duplexing options and choices (STR #915)
 660         - cups-lpd now honors remote banner requests with the
 661           "standard" banner whenever a printer does not have one
 662           defined (STR #1220)
 663         - The scheduler's denial-of-service checks did not work
 664           properly with IPv6 addresses (STR #1134)
 665         - The lp and lpr commands did not error out properly when
 666           they were unable to write to a temporary file (STR
 667           #1129)

 669           comments in Windows NT driver output (STR #1085)
 670         - "lpstat -l -p" incorrectly reported the printer
 671           interface (STR #936)
 672         - The web interface now operates exclusively with the
 673           UTF-8 encoding, and sends the appropriate character set
 674           and header information to the web browser (STR #919,
 675           STR #1007)
 676         - Added a "set allowed users" interface to the web
 677           interface so that you can set the list of allowed or
 678           denied users/groups for a printer or class.
 679         - Disallow the "#" character in printer names, since it
 680           has special meaning in the shell, config files, and in
 681           URIs (STR #917, STR #1202)
 682         - Added a new application/x-csource MIME type, and
 683           support for it to the texttops filter so that you can
 684           pretty print plain text files without the C/C++
 685           keywords being highlighted.
 686         - The pdftops filter did not compile with GCC 4.0 (STR
 687           #1226)
 688         - The texttops filter did not highlight preprocessor
 689           directives followed by a tab properly.
 690         - HP PJL output now uses both JOB DISPLAY and RDYMSG

 692           display (STR #1218)
 693         - Local authentication certificates are now stored in
 694           /var/run/cups/certs by default instead of
 695           /etc/cups/certs (STR #1211)
 696         - Backends now use "&" to separate options in device
 697           URIs; "+" is still recognized but is deprecated (STR
 698           #842)
 699         - The USB backend no longer supports the usb:/dev/foo
 700           format on systems that support device ID queries.
 701         - Forced classification markings did not work when the
 702           job-sheets parameters were "none,none".
 703         - "lpstat -l -p" incorrectly showed all users as allowed,
 704           even if the queue was restricted to certain users (STR
 705           #801)
 706         - The scheduler now automatically detects SSL/TLS clients
 707           without using the SSLPort/SSLListen directives.
 708         - The CUPS API and scheduler no longer support SSLv2-
 709           encrypted connections.
 710         - Updated the cupsaddsmb utility to correctly export the
 711           CUPS driver for Windows.
 712         - Fixed a signal-handling bug in httpRead() which
 713           ultimately caused the server to print multiple copies
 714           when it was busy (STR #1184)
 715         - The cupsFile API now uses the O_APPEND option when
 716           opening files in append mode (STR #990)
 717         - The md5.h header and md5_* functions are now officially
 718           private and have been renamed to avoid conflicts with
 719           other implementations with the same name.
 720         - The pdftops filter incorrectly embedded some Type1
 721           fonts (STR #1093)
 722         - The scheduler didn't detect a closed connection in the
 723           middle of an IPP request (STR #1153)
 724         - The scheduler could block trying to read the job status
 725           if there was input pending and the job was cancelled in
 726           the same input cycle (STR #1157)
 727         - The scheduler could crash when deleting a class due to
 728           infinite recursion.
 729         - Updated the Zebra ZPL label printer driver to use the
 730           run-length encoding and support more options.
 731         - Updated serial backend to scan for /dev/ttyC* as well
 732           as /dev/ttyc* for Cyclades serial ports (STR #1049)
 733         - The scheduler could hang reading the job status under
 734           certain circumstances (STR #1068)
 735         - The USB backend termination signal code was inverted
 736           (STR #1046)
 737         - Moved enable and disable commands to sbindir to be
 738           consistent.
 739         - Added new cupsRasterInterpretPPD() function for RIP
 740           filters to setup the raster page header from
 741           PostScript commands in a PPD file.
 742         - The CUPS browsing protocol now offers a "delete" bit
 743           to remove printers as soon as they are deleted on the
 744           server or as soon as the server shuts down gracefully
 745           (STR #793)
 746         - The CUPS_SERVER and ServerName directives (client.conf
 747           and ~/.cupsrc) may now contain names of the form
 748           "server:port" and "/path/to/domain/socket".

 754           administrator to add printer URI options to the browse
 755           URI, e.g. "encryption=required" (STR #732)
 756         - Added BrowseRemoteOptions directive to allow the
 757           administrator to add standard URI options to the
 758           remote printer URI, e.g. "encryption=required" (STR
 759           #732)
 760         - Now put "-I.." compiler option in front of all others
 761           to ensure that local CUPS headers are used before
 762           installed headers (STR #437)
 763         - New cupsLangPrintf() and cupsLangPuts() for localized
 764           interfaces.

 771         - New error policy mechanism to control how aborted
 772           backend errors are handled by the scheduler
 773           (abort-job, retry-job, requeue-job, stop-printer)

 775           wheel and a separate grayscale ramp.
 776         - A single backend process is now run to send all print
 777           data for a job.
