  38         - The pdftops filter now supports masked images (STR
  39           #281)
  40         - The pdftops filter produced large output when rendering
  41           PDF files containing lot of repeated images (STR #327)
  42         - The pdftops filter now minimizes print processing of
  43           PDF files when using the page-ranges option (STR #273)

  45         - Added new cupsBackchannelRead() and
  46           cupsBackchannelWrite() functions, as well as
  47           backchannel support to the parallel, serial, socket,
  48           and USB backends (STR #1252)
  49         - The parallel and USB backends now treat a "no space
  50           available" error as an out-of-paper condition (STR
  51           #1225)
  52         - The "lpc" command now supports the "status all" command
  53           (STR #1004)
  54         - ippReadIO() did not read collections properly (STR
  55           #1249)
  56         - The "make test" script now creates the test files in
  57           "/tmp/cups-$USER" instead of "/tmp/$USER" (STR #981)
  58         - All backends now abort on error when printing a job to
  59           a class - this allows the next printer in the class to
  60           print the job (STR #1084)
  61         - The scheduler now verifies that a printer supports
  62           Letter or A4 media sizes before setting them as the
  63           initial default (STR #1250)
  64         - The cupstestppd program now flags bad Resolution
  65           options (STR #1269)
  66         - The USB backend now retries printing when the printer
  67           is disconnected or turned off (STR #1267)
  68         - Added new httpGetHostname() function to CUPS API, and
  69           use it instead of gethostname() so that the web
  70           interface will work correctly on systems whose hostname
  71           is not the FQDN (STR #1266)
  72         - The scheduler now stops printers if the backend for the
  73           queue is missing on startup (STR #1265)
  74         - The configure script now supports "--disable-library"
  75           to disable particular image file format support
  76           libraries, even if they are available on the build
  77           system (STR #1248)
  78         - The IPP backend did not always report on the total
  79           number of pages that were printed (STR #1251)
  80         - The lpstat program could display garbage date and time
  81           values for locales whose date format exceeded 31
  82           characters (STR #1263)
  83         - The cupstestppd program would segfault when testing
  84           certain broken PPD files (STR #1268)
  85         - Dramatically reduced the overhead of implicit classes.
  86         - Added new cupsDir*() functions to CUPS API.
  87         - Printers can now be published individually for sharing.
  88         - Fixed a bug in the scheduler's startup signalling code
  89           which caused cupsd to send the SIGUSR1 signal to the
  90           init process instead of the original parent process
  91           (STR #1258)
  92         - Added new on-line help CGI to web interface to provide
  93           searchable help.
  94         - Devices are now tracked dynamically, with each query
  95           doing a new device scan.  This eliminates a previous
  96           startup delay caused by slow backends and allows new
  97           printers to be seen without restarting the server,
  98           however it limits the amount of device URI checking
  99           that can be done (basically now the scheduler only
 100           requires a URI with a method that is a listed backend)
 101         - Added new printer auto-detection, server configuration,
 102           and log file viewing to the administration web page.
 103         - Added new "set allowed users" web interface to set the
 104           list of allowed users for a printer or class.
 105         - The scheduler, command-line, and web interfaces now
 106           limit the list of printers and classes to those
 107           accessible by a user.
 108         - cupsMarkOptions() now handles more non-standard
 109           duplexing options and choices (STR #915)
 110         - cups-lpd now honors remote banner requests with the
 111           "standard" banner whenever a printer does not have one
 112           defined (STR #1220)
 113         - The scheduler's denial-of-service checks did not work
 114           properly with IPv6 addresses (STR #1134)
 115         - The lp and lpr commands did not error out properly when
 116           they were unable to write to a temporary file (STR
 117           #1129)
 118         - The pstops filter did not handle Adobe-specific
 119           comments in Windows NT driver output (STR #1085)
 120         - "lpstat -l -p" incorrectly reported the printer
 121           interface (STR #936)
 122         - The web interface now operates exclusively with the
 123           UTF-8 encoding, and sends the appropriate character set
 124           and header information to the web browser (STR #919,
 125           STR #1007)
 126         - Added a "set allowed users" interface to the web
 127           interface so that you can set the list of allowed or
 128           denied users/groups for a printer or class.
 129         - Disallow the "#" character in printer names, since it
 130           has special meaning in the shell, config files, and in
 131           URIs (STR #917, STR #1202)
 132         - Added a new application/x-csource MIME type, and
 133           support for it to the texttops filter so that you can
 134           pretty print plain text files without the C/C++
 135           keywords being highlighted.
 136         - The pdftops filter did not compile with GCC 4.0 (STR
 137           #1226)
 138         - The texttops filter did not highlight preprocessor
 139           directives followed by a tab properly.
 140         - HP PJL output now uses both JOB DISPLAY and RDYMSG
 141           commands to show the current job on the printer's
 142           display (STR #1218)
 143         - Local authentication certificates are now stored in
 144           /var/run/cups/certs by default instead of
 145           /etc/cups/certs (STR #1211)
 146         - Backends now use "&" to separate options in device
 147           URIs; "+" is still recognized but is deprecated (STR
 148           #842)
 149         - The USB backend no longer supports the usb:/dev/foo
 150           format on systems that support device ID queries.
 151         - Forced classification markings did not work when the
 152           job-sheets parameters were "none,none".
 153         - "lpstat -l -p" incorrectly showed all users as allowed,
 154           even if the queue was restricted to certain users (STR
 155           #801)
 156         - The scheduler now automatically detects SSL/TLS clients
 157           without using the SSLPort/SSLListen directives.
 158         - The CUPS API and scheduler no longer support SSLv2-
 159           encrypted connections.
 160         - Updated the cupsaddsmb utility to correctly export the
 161           CUPS driver for Windows.
 162         - Fixed a signal-handling bug in httpRead() which
 163           ultimately caused the server to print multiple copies
 164           when it was busy (STR #1184)
 165         - The cupsFile API now uses the O_APPEND option when
 166           opening files in append mode (STR #990)
 167         - The md5.h header and md5_* functions are now officially
 168           private and have been renamed to avoid conflicts with
 169           other implementations with the same name.
 170         - The pdftops filter incorrectly embedded some Type1
 171           fonts (STR #1093)
 172         - The scheduler didn't detect a closed connection in the
 173           middle of an IPP request (STR #1153)
 174         - The scheduler could block trying to read the job status
 175           if there was input pending and the job was cancelled in
 176           the same input cycle (STR #1157)
 177         - The scheduler could crash when deleting a class due to
 178           infinite recursion.
 179         - Updated the Zebra ZPL label printer driver to use the
 180           run-length encoding and support more options.
 181         - Updated serial backend to scan for /dev/ttyC* as well
 182           as /dev/ttyc* for Cyclades serial ports (STR #1049)
 183         - The scheduler could hang reading the job status under
 184           certain circumstances (STR #1068)
 185         - The USB backend termination signal code was inverted
 186           (STR #1046)
 187         - Moved enable and disable commands to sbindir to be
 188           consistent.
 189         - Added new cupsRasterInterpretPPD() function for RIP
 190           filters to setup the raster page header from
 191           PostScript commands in a PPD file.
 192         - The CUPS browsing protocol now offers a "delete" bit
 193           to remove printers as soon as they are deleted on the
 194           server or as soon as the server shuts down gracefully
 195           (STR #793)
 196         - The CUPS_SERVER and ServerName directives (client.conf
 197           and ~/.cupsrc) may now contain names of the form
 198           "server:port" and "/path/to/domain/socket".
 199         - The "cancel -u user" command now works for ordinary
 200           users (STR #751)

 202         - Added domain socket support (STR #656)
 203         - Added BrowseLocalOptions directive to allow the
 204           administrator to add printer URI options to the browse
 205           URI, e.g. "encryption=required" (STR #732)
 206         - Added BrowseRemoteOptions directive to allow the
 207           administrator to add standard URI options to the
 208           remote printer URI, e.g. "encryption=required" (STR
 209           #732)
 210         - Now put "-I.." compiler option in front of all others
 211           to ensure that local CUPS headers are used before
 212           installed headers (STR #437)
 213         - New cupsLangPrintf() and cupsLangPuts() for localized
 214           interfaces.

 218         - New policy mechanism allows per-operation and
 219           per-printer control over what users and groups are
 220           allowed to do various IPP operations.
 221         - New error policy mechanism to control how aborted
 222           backend errors are handled by the scheduler
 223           (abort-job, retry-job, requeue-job, stop-printer)
 224         - Updated the printer test page with a better color
 225           wheel and a separate grayscale ramp.
 226         - A single backend process is now run to send all print
 227           data for a job.
 228         - Backends and filters can now send and receive
 229           backchannel data over file descriptor 3.
 230         - Updated the raster stream format to support more
 231           user-defined attributes and to do compression of the
 232           page data.
