  30           rastertolabel (a symlink is installed so that existing
  31           queues continue to work) and now also supports Zebra's
  32           CPCL language.
  33         - The lpstat command could show the wrong active job for
  34           a printer (STR #1301)

  65           attribute to localize banner pages (STR #386)
  66         - The scheduler now returns the address that was used to
  67           connect to it (STR #1076)
  68         - Fixed a problem with N-up printing and OpenOffice (STR

  70         - Added support for the GCC position independent
  71           executable options (STR #1209)
  72         - Added new BrowseLocalProtocols and
  73           BrowseRemoteProtocols directives to cupsd.conf,

 102           and USB backends (STR #1252)
 103         - The parallel and USB backends now treat a "no space
 104           available" error as an out-of-paper condition (STR
 105           #1225)
 106         - The "lpc" command now supports the "status all" command
 107           (STR #1004)

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

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

 258           administrator to add printer URI options to the browse
 259           URI, e.g. "encryption=required" (STR #732)
 260         - Added BrowseRemoteOptions directive to allow the
 261           administrator to add standard URI options to the
 262           remote printer URI, e.g. "encryption=required" (STR
 263           #732)
 264         - Now put "-I.." compiler option in front of all others
 265           to ensure that local CUPS headers are used before
 266           installed headers (STR #437)
 267         - New cupsLangPrintf() and cupsLangPuts() for localized
 268           interfaces.
