 144           rastertolabel (a symlink is installed so that existing
 145           queues continue to work) and now also supports Zebra's
 146           CPCL language.
 147         - The lpstat command could show the wrong active job for
 148           a printer (STR #1301)

 183           #576)
 184         - Added support for the GCC position independent
 185           executable options (STR #1209)
 186         - Added new BrowseLocalProtocols and
 187           BrowseRemoteProtocols directives to cupsd.conf,

 226         - All backends now abort on error when printing a job to
 227           a class - this allows the next printer in the class to

 229         - The scheduler now verifies that a printer supports
 230           Letter or A4 media sizes before setting them as the

 235           is disconnected or turned off (STR #1267)
 236         - Added new httpGetHostname() function to CUPS API, and
 237           use it instead of gethostname() so that the web
 238           interface will work correctly on systems whose hostname
 239           is not the FQDN (STR #1266)
 240         - The scheduler now stops printers if the backend for the
 241           queue is missing on startup (STR #1265)
 242         - The configure script now supports "--disable-library"
 243           to disable particular image file format support
 244           libraries, even if they are available on the build
 245           system (STR #1248)
 246         - The IPP backend did not always report on the total
 247           number of pages that were printed (STR #1251)
 248         - The lpstat program could display garbage date and time
 249           values for locales whose date format exceeded 31
 250           characters (STR #1263)
 251         - The cupstestppd program would segfault when testing
 252           certain broken PPD files (STR #1268)
 253         - Dramatically reduced the overhead of implicit classes.
 254         - Added new cupsDir*() functions to CUPS API.
 255         - Printers can now be published individually for sharing.
 256         - Fixed a bug in the scheduler's startup signalling code
 257           which caused cupsd to send the SIGUSR1 signal to the
 258           init process instead of the original parent process
 259           (STR #1258)
 260         - Added new on-line help CGI to web interface to provide
 261           searchable help.
 262         - Devices are now tracked dynamically, with each query
 263           doing a new device scan.  This eliminates a previous
 264           startup delay caused by slow backends and allows new
 265           printers to be seen without restarting the server,
 266           however it limits the amount of device URI checking
 267           that can be done (basically now the scheduler only
 268           requires a URI with a method that is a listed backend)
 269         - Added new printer auto-detection, server configuration,
 270           and log file viewing to the administration web page.
 271         - Added new "set allowed users" web interface to set the
 272           list of allowed users for a printer or class.
 273         - The scheduler, command-line, and web interfaces now
 274           limit the list of printers and classes to those
 275           accessible by a user.
 276         - cupsMarkOptions() now handles more non-standard
 277           duplexing options and choices (STR #915)
 278         - cups-lpd now honors remote banner requests with the
 279           "standard" banner whenever a printer does not have one
 280           defined (STR #1220)
 281         - The scheduler's denial-of-service checks did not work
 282           properly with IPv6 addresses (STR #1134)
 283         - The lp and lpr commands did not error out properly when
 284           they were unable to write to a temporary file (STR
 285           #1129)
 286         - The pstops filter did not handle Adobe-specific
 287           comments in Windows NT driver output (STR #1085)
 288         - "lpstat -l -p" incorrectly reported the printer
 289           interface (STR #936)
 290         - The web interface now operates exclusively with the
 291           UTF-8 encoding, and sends the appropriate character set
 292           and header information to the web browser (STR #919,
 293           STR #1007)
 294         - Added a "set allowed users" interface to the web
 295           interface so that you can set the list of allowed or
 296           denied users/groups for a printer or class.
 297         - Disallow the "#" character in printer names, since it
 298           has special meaning in the shell, config files, and in
 299           URIs (STR #917, STR #1202)
 300         - Added a new application/x-csource MIME type, and
 301           support for it to the texttops filter so that you can
 302           pretty print plain text files without the C/C++
 303           keywords being highlighted.
 304         - The pdftops filter did not compile with GCC 4.0 (STR
 305           #1226)
 306         - The texttops filter did not highlight preprocessor
 307           directives followed by a tab properly.
 308         - HP PJL output now uses both JOB DISPLAY and RDYMSG
 309           commands to show the current job on the printer's
 310           display (STR #1218)
 311         - Local authentication certificates are now stored in
 312           /var/run/cups/certs by default instead of
 313           /etc/cups/certs (STR #1211)
 314         - Backends now use "&" to separate options in device
 315           URIs; "+" is still recognized but is deprecated (STR
 316           #842)
 317         - The USB backend no longer supports the usb:/dev/foo
 318           format on systems that support device ID queries.
 319         - Forced classification markings did not work when the
 320           job-sheets parameters were "none,none".
 321         - "lpstat -l -p" incorrectly showed all users as allowed,
 322           even if the queue was restricted to certain users (STR

 334           opening files in append mode (STR #990)
 335         - The md5.h header and md5_* functions are now officially
 336           private and have been renamed to avoid conflicts with
 337           other implementations with the same name.

 344           the same input cycle (STR #1157)
 345         - The scheduler could crash when deleting a class due to
 346           infinite recursion.

 359           PostScript commands in a PPD file.
 360         - The CUPS browsing protocol now offers a "delete" bit
 361           to remove printers as soon as they are deleted on the
 362           server or as soon as the server shuts down gracefully
 363           (STR #793)
 364         - The CUPS_SERVER and ServerName directives (client.conf
 365           and ~/.cupsrc) may now contain names of the form
 366           "server:port" and "/path/to/domain/socket".

 371         - Added BrowseLocalOptions directive to allow the
 372           administrator to add printer URI options to the browse
 373           URI, e.g. "encryption=required" (STR #732)
 374         - Added BrowseRemoteOptions directive to allow the
 375           administrator to add standard URI options to the
 376           remote printer URI, e.g. "encryption=required" (STR
 377           #732)
 378         - Now put "-I.." compiler option in front of all others
 379           to ensure that local CUPS headers are used before
 380           installed headers (STR #437)
 381         - New cupsLangPrintf() and cupsLangPuts() for localized
 382           interfaces.

 387           per-printer control over what users and groups are
 388           allowed to do various IPP operations.
 389         - New error policy mechanism to control how aborted
 390           backend errors are handled by the scheduler

 395           data for a job.
 396         - Backends and filters can now send and receive
 397           backchannel data over file descriptor 3.
 398         - Updated the raster stream format to support more
 399           user-defined attributes and to do compression of the
 400           page data.
