  37           rastertolabel (a symlink is installed so that existing
  38           queues continue to work) and now also supports Zebra's
  39           CPCL language.
  40         - The lpstat command could show the wrong active job for
  41           a printer (STR #1301)

  72           attribute to localize banner pages (STR #386)
  73         - The scheduler now returns the address that was used to
  74           connect to it (STR #1076)

  79         - Added new BrowseLocalProtocols and
  80           BrowseRemoteProtocols directives to cupsd.conf,

 109           and USB backends (STR #1252)
 110         - The parallel and USB backends now treat a "no space
 111           available" error as an out-of-paper condition (STR
 112           #1225)
 113         - The "lpc" command now supports the "status all" command
 114           (STR #1004)

 117         - The "make test" script now creates the test files in
 118           "/tmp/cups-$USER" instead of "/tmp/$USER" (STR #981)
 119         - All backends now abort on error when printing a job to
 120           a class - this allows the next printer in the class to
 121           print the job (STR #1084)
 122         - The scheduler now verifies that a printer supports
 123           Letter or A4 media sizes before setting them as the
 124           initial default (STR #1250)
 125         - The cupstestppd program now flags bad Resolution
 126           options (STR #1269)
 127         - The USB backend now retries printing when the printer
 128           is disconnected or turned off (STR #1267)
 129         - Added new httpGetHostname() function to CUPS API, and
 130           use it instead of gethostname() so that the web
 131           interface will work correctly on systems whose hostname
 132           is not the FQDN (STR #1266)
 133         - The scheduler now stops printers if the backend for the
 134           queue is missing on startup (STR #1265)
 135         - The configure script now supports "--disable-library"
 136           to disable particular image file format support
 137           libraries, even if they are available on the build
 138           system (STR #1248)
 139         - The IPP backend did not always report on the total
 140           number of pages that were printed (STR #1251)
 141         - The lpstat program could display garbage date and time
 142           values for locales whose date format exceeded 31
 143           characters (STR #1263)
 144         - The cupstestppd program would segfault when testing
 145           certain broken PPD files (STR #1268)
 146         - Dramatically reduced the overhead of implicit classes.
 147         - Added new cupsDir*() functions to CUPS API.
 148         - Printers can now be published individually for sharing.
 149         - Fixed a bug in the scheduler's startup signalling code
 150           which caused cupsd to send the SIGUSR1 signal to the
 151           init process instead of the original parent process
 152           (STR #1258)
 153         - Added new on-line help CGI to web interface to provide
 154           searchable help.
 155         - Devices are now tracked dynamically, with each query
 156           doing a new device scan.  This eliminates a previous
 157           startup delay caused by slow backends and allows new
 158           printers to be seen without restarting the server,
 159           however it limits the amount of device URI checking
 160           that can be done (basically now the scheduler only
 161           requires a URI with a method that is a listed backend)
 162         - Added new printer auto-detection, server configuration,
 163           and log file viewing to the administration web page.
 164         - Added new "set allowed users" web interface to set the
 165           list of allowed users for a printer or class.
 166         - The scheduler, command-line, and web interfaces now
 167           limit the list of printers and classes to those
 168           accessible by a user.
 169         - cupsMarkOptions() now handles more non-standard
 170           duplexing options and choices (STR #915)
 171         - cups-lpd now honors remote banner requests with the
 172           "standard" banner whenever a printer does not have one
 173           defined (STR #1220)
 174         - The scheduler's denial-of-service checks did not work
 175           properly with IPv6 addresses (STR #1134)
 176         - The lp and lpr commands did not error out properly when
 177           they were unable to write to a temporary file (STR
 178           #1129)
 179         - The pstops filter did not handle Adobe-specific
 180           comments in Windows NT driver output (STR #1085)
 181         - "lpstat -l -p" incorrectly reported the printer
 182           interface (STR #936)
 183         - The web interface now operates exclusively with the
 184           UTF-8 encoding, and sends the appropriate character set
 185           and header information to the web browser (STR #919,
 186           STR #1007)
 187         - Added a "set allowed users" interface to the web
 188           interface so that you can set the list of allowed or
 189           denied users/groups for a printer or class.
 190         - Disallow the "#" character in printer names, since it
 191           has special meaning in the shell, config files, and in
 192           URIs (STR #917, STR #1202)
 193         - Added a new application/x-csource MIME type, and
 194           support for it to the texttops filter so that you can
 195           pretty print plain text files without the C/C++
 196           keywords being highlighted.
 197         - The pdftops filter did not compile with GCC 4.0 (STR
 198           #1226)
 199         - The texttops filter did not highlight preprocessor
 200           directives followed by a tab properly.
 201         - HP PJL output now uses both JOB DISPLAY and RDYMSG
 202           commands to show the current job on the printer's
 203           display (STR #1218)
 204         - Local authentication certificates are now stored in
 205           /var/run/cups/certs by default instead of
 206           /etc/cups/certs (STR #1211)
 207         - Backends now use "&" to separate options in device
 208           URIs; "+" is still recognized but is deprecated (STR
 209           #842)
 210         - The USB backend no longer supports the usb:/dev/foo
 211           format on systems that support device ID queries.
 212         - Forced classification markings did not work when the
 213           job-sheets parameters were "none,none".
 214         - "lpstat -l -p" incorrectly showed all users as allowed,
 215           even if the queue was restricted to certain users (STR
 216           #801)
 217         - The scheduler now automatically detects SSL/TLS clients
 218           without using the SSLPort/SSLListen directives.
 219         - The CUPS API and scheduler no longer support SSLv2-
 220           encrypted connections.
 221         - Updated the cupsaddsmb utility to correctly export the
 222           CUPS driver for Windows.
 223         - Fixed a signal-handling bug in httpRead() which
 224           ultimately caused the server to print multiple copies
 225           when it was busy (STR #1184)
 226         - The cupsFile API now uses the O_APPEND option when
 227           opening files in append mode (STR #990)
 228         - The md5.h header and md5_* functions are now officially
 229           private and have been renamed to avoid conflicts with
 230           other implementations with the same name.
 231         - The pdftops filter incorrectly embedded some Type1
 232           fonts (STR #1093)
 233         - The scheduler didn't detect a closed connection in the
 234           middle of an IPP request (STR #1153)
 235         - The scheduler could block trying to read the job status
 236           if there was input pending and the job was cancelled in
 237           the same input cycle (STR #1157)
 238         - The scheduler could crash when deleting a class due to
 239           infinite recursion.
 240         - Updated the Zebra ZPL label printer driver to use the
 241           run-length encoding and support more options.
 242         - Updated serial backend to scan for /dev/ttyC* as well
 243           as /dev/ttyc* for Cyclades serial ports (STR #1049)
 244         - The scheduler could hang reading the job status under
 245           certain circumstances (STR #1068)

 249           consistent.
 250         - Added new cupsRasterInterpretPPD() function for RIP
 251           filters to setup the raster page header from
 252           PostScript commands in a PPD file.
 253         - The CUPS browsing protocol now offers a "delete" bit
 254           to remove printers as soon as they are deleted on the
 255           server or as soon as the server shuts down gracefully
 256           (STR #793)
 257         - The CUPS_SERVER and ServerName directives (client.conf
 258           and ~/.cupsrc) may now contain names of the form
 259           "server:port" and "/path/to/domain/socket".

 265           administrator to add printer URI options to the browse
 266           URI, e.g. "encryption=required" (STR #732)
 267         - Added BrowseRemoteOptions directive to allow the
 268           administrator to add standard URI options to the
 269           remote printer URI, e.g. "encryption=required" (STR
 270           #732)
 271         - Now put "-I.." compiler option in front of all others
 272           to ensure that local CUPS headers are used before
 273           installed headers (STR #437)
 274         - New cupsLangPrintf() and cupsLangPuts() for localized
 275           interfaces.
