  69           rastertolabel (a symlink is installed so that existing
  70           queues continue to work) and now also supports Zebra's
  71           CPCL language.
  72         - The lpstat command could show the wrong active job for
  73           a printer (STR #1301)

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

 109         - Added support for the GCC position independent
 110           executable options (STR #1209)
 111         - Added new BrowseLocalProtocols and
 112           BrowseRemoteProtocols directives to cupsd.conf,

 151         - All backends now abort on error when printing a job to
 152           a class - this allows the next printer in the class to
 153           print the job (STR #1084)
 154         - The scheduler now verifies that a printer supports
 155           Letter or A4 media sizes before setting them as the
 156           initial default (STR #1250)
 157         - The cupstestppd program now flags bad Resolution
 158           options (STR #1269)
 159         - The USB backend now retries printing when the printer
 160           is disconnected or turned off (STR #1267)
 161         - Added new httpGetHostname() function to CUPS API, and
 162           use it instead of gethostname() so that the web
 163           interface will work correctly on systems whose hostname
 164           is not the FQDN (STR #1266)
 165         - The scheduler now stops printers if the backend for the
 166           queue is missing on startup (STR #1265)
 167         - The configure script now supports "--disable-library"
 168           to disable particular image file format support
 169           libraries, even if they are available on the build
 170           system (STR #1248)
 171         - The IPP backend did not always report on the total
 172           number of pages that were printed (STR #1251)
 173         - The lpstat program could display garbage date and time
 174           values for locales whose date format exceeded 31
 175           characters (STR #1263)
 176         - The cupstestppd program would segfault when testing
 177           certain broken PPD files (STR #1268)
 178         - Dramatically reduced the overhead of implicit classes.
 179         - Added new cupsDir*() functions to CUPS API.
 180         - Printers can now be published individually for sharing.
 181         - Fixed a bug in the scheduler's startup signalling code
 182           which caused cupsd to send the SIGUSR1 signal to the
 183           init process instead of the original parent process
 184           (STR #1258)
 185         - Added new on-line help CGI to web interface to provide
 186           searchable help.
 187         - Devices are now tracked dynamically, with each query
 188           doing a new device scan.  This eliminates a previous
 189           startup delay caused by slow backends and allows new
 190           printers to be seen without restarting the server,
 191           however it limits the amount of device URI checking
 192           that can be done (basically now the scheduler only
 193           requires a URI with a method that is a listed backend)
 194         - Added new printer auto-detection, server configuration,
 195           and log file viewing to the administration web page.
 196         - Added new "set allowed users" web interface to set the
 197           list of allowed users for a printer or class.
 198         - The scheduler, command-line, and web interfaces now
 199           limit the list of printers and classes to those
 200           accessible by a user.
 201         - cupsMarkOptions() now handles more non-standard
 202           duplexing options and choices (STR #915)
 203         - cups-lpd now honors remote banner requests with the
 204           "standard" banner whenever a printer does not have one
 205           defined (STR #1220)
 206         - The scheduler's denial-of-service checks did not work
 207           properly with IPv6 addresses (STR #1134)
 208         - The lp and lpr commands did not error out properly when
 209           they were unable to write to a temporary file (STR
 210           #1129)
 211         - The pstops filter did not handle Adobe-specific
 212           comments in Windows NT driver output (STR #1085)
 213         - "lpstat -l -p" incorrectly reported the printer
 214           interface (STR #936)
 215         - The web interface now operates exclusively with the
 216           UTF-8 encoding, and sends the appropriate character set
 217           and header information to the web browser (STR #919,
 218           STR #1007)
 219         - Added a "set allowed users" interface to the web
 220           interface so that you can set the list of allowed or
 221           denied users/groups for a printer or class.
 222         - Disallow the "#" character in printer names, since it
 223           has special meaning in the shell, config files, and in
 224           URIs (STR #917, STR #1202)
 225         - Added a new application/x-csource MIME type, and
 226           support for it to the texttops filter so that you can
 227           pretty print plain text files without the C/C++
 228           keywords being highlighted.
 229         - The pdftops filter did not compile with GCC 4.0 (STR
 230           #1226)
 231         - The texttops filter did not highlight preprocessor
 232           directives followed by a tab properly.
 233         - HP PJL output now uses both JOB DISPLAY and RDYMSG
 234           commands to show the current job on the printer's
 235           display (STR #1218)
 236         - Local authentication certificates are now stored in
 237           /var/run/cups/certs by default instead of
 238           /etc/cups/certs (STR #1211)
 239         - Backends now use "&" to separate options in device
 240           URIs; "+" is still recognized but is deprecated (STR
 241           #842)
 242         - The USB backend no longer supports the usb:/dev/foo
 243           format on systems that support device ID queries.
 244         - Forced classification markings did not work when the
 245           job-sheets parameters were "none,none".
 246         - "lpstat -l -p" incorrectly showed all users as allowed,
 247           even if the queue was restricted to certain users (STR
 248           #801)
 249         - The scheduler now automatically detects SSL/TLS clients
 250           without using the SSLPort/SSLListen directives.
 251         - The CUPS API and scheduler no longer support SSLv2-
 252           encrypted connections.
 253         - Updated the cupsaddsmb utility to correctly export the
 254           CUPS driver for Windows.
 255         - Fixed a signal-handling bug in httpRead() which
 256           ultimately caused the server to print multiple copies
 257           when it was busy (STR #1184)
 258         - The cupsFile API now uses the O_APPEND option when
 259           opening files in append mode (STR #990)
 260         - The md5.h header and md5_* functions are now officially
 261           private and have been renamed to avoid conflicts with
 262           other implementations with the same name.
 263         - The pdftops filter incorrectly embedded some Type1
 264           fonts (STR #1093)
 265         - The scheduler didn't detect a closed connection in the
 266           middle of an IPP request (STR #1153)
 267         - The scheduler could block trying to read the job status
 268           if there was input pending and the job was cancelled in
 269           the same input cycle (STR #1157)
 270         - The scheduler could crash when deleting a class due to
 271           infinite recursion.
 272         - Updated the Zebra ZPL label printer driver to use the
 273           run-length encoding and support more options.
 274         - Updated serial backend to scan for /dev/ttyC* as well
 275           as /dev/ttyc* for Cyclades serial ports (STR #1049)
 276         - The scheduler could hang reading the job status under
 277           certain circumstances (STR #1068)
 278         - The USB backend termination signal code was inverted
 279           (STR #1046)

 281           consistent.
 282         - Added new cupsRasterInterpretPPD() function for RIP
 283           filters to setup the raster page header from
 284           PostScript commands in a PPD file.
 285         - The CUPS browsing protocol now offers a "delete" bit
 286           to remove printers as soon as they are deleted on the
 287           server or as soon as the server shuts down gracefully
 288           (STR #793)
 289         - The CUPS_SERVER and ServerName directives (client.conf
 290           and ~/.cupsrc) may now contain names of the form
 291           "server:port" and "/path/to/domain/socket".

 298           URI, e.g. "encryption=required" (STR #732)
 299         - Added BrowseRemoteOptions directive to allow the
 300           administrator to add standard URI options to the
 301           remote printer URI, e.g. "encryption=required" (STR
 302           #732)
 303         - Now put "-I.." compiler option in front of all others
 304           to ensure that local CUPS headers are used before
 305           installed headers (STR #437)
