  23         - When the default policy was not set or set to a non-

  40         - Added --enable-32bit and --enable-64bit configure

  49           arrays)
  50         - The ppdEmitString() function did not compute the
  51           required buffer size properly, leading to dropped

  99           and printers.
 100         - cupsaddsmb now accepts a password on the command-line

 113         - The scheduler now logs log file open errors to the
 114           system log (STR #1289)

 120         - The rastertodymo driver has been renamed to
 121           rastertolabel (a symlink is installed so that existing
 122           queues continue to work) and now also supports Zebra's
 123           CPCL language.
 124         - The lpstat command could show the wrong active job for
 125           a printer (STR #1301)
 126         - Fixed a potential crash problem in the scheduler when
 127           aborting a CGI program (STR #1290)
 128         - Added a "cancel all jobs" button to the class and
 129           printer web interfaces (STR #1140)
 130         - The add-printer web page now shows the

 135         - CUPS now handles HTTP request/response lines up to 32k

 156           attribute to localize banner pages (STR #386)
 157         - The scheduler now returns the address that was used to
 158           connect to it (STR #1076)
 159         - Fixed a problem with N-up printing and OpenOffice (STR
 160           #576)
 161         - Added support for the GCC position independent
 162           executable options (STR #1209)
 163         - Added new BrowseLocalProtocols and
 164           BrowseRemoteProtocols directives to cupsd.conf,
 165           allowing for different browse protocols for local and
 166           remote printers (STR #877)

 194         - The parallel and USB backends now treat a "no space

 203         - All backends now abort on error when printing a job to
 204           a class - this allows the next printer in the class to
 205           print the job (STR #1084)
 206         - The scheduler now verifies that a printer supports
 207           Letter or A4 media sizes before setting them as the
 208           initial default (STR #1250)
 209         - The cupstestppd program now flags bad Resolution
 210           options (STR #1269)
 211         - The USB backend now retries printing when the printer
 212           is disconnected or turned off (STR #1267)
 213         - Added new httpGetHostname() function to CUPS API, and
 214           use it instead of gethostname() so that the web
 215           interface will work correctly on systems whose hostname
 216           is not the FQDN (STR #1266)
 217         - The scheduler now stops printers if the backend for the
 218           queue is missing on startup (STR #1265)
 219         - The configure script now supports "--disable-library"
 220           to disable particular image file format support
 221           libraries, even if they are available on the build
 222           system (STR #1248)
 223         - The IPP backend did not always report on the total
 224           number of pages that were printed (STR #1251)
 225         - The lpstat program could display garbage date and time
 226           values for locales whose date format exceeded 31
 227           characters (STR #1263)
 228         - The cupstestppd program would segfault when testing
 229           certain broken PPD files (STR #1268)
 230         - Dramatically reduced the overhead of implicit classes.
 231         - Added new cupsDir*() functions to CUPS API.
 232         - Printers can now be published individually for sharing.
 233         - Fixed a bug in the scheduler's startup signalling code
 234           which caused cupsd to send the SIGUSR1 signal to the
 235           init process instead of the original parent process
 236           (STR #1258)
 237         - Added new on-line help CGI to web interface to provide
 238           searchable help.
 239         - Devices are now tracked dynamically, with each query
 240           doing a new device scan.  This eliminates a previous
 241           startup delay caused by slow backends and allows new
 242           printers to be seen without restarting the server,
 243           however it limits the amount of device URI checking
 244           that can be done (basically now the scheduler only
 245           requires a URI with a method that is a listed backend)
 246         - Added new printer auto-detection, server configuration,
 247           and log file viewing to the administration web page.
 248         - Added new "set allowed users" web interface to set the
 249           list of allowed users for a printer or class.
 250         - The scheduler, command-line, and web interfaces now
 251           limit the list of printers and classes to those
 252           accessible by a user.
 253         - cupsMarkOptions() now handles more non-standard
 254           duplexing options and choices (STR #915)
 255         - cups-lpd now honors remote banner requests with the
 256           "standard" banner whenever a printer does not have one
 257           defined (STR #1220)
 258         - The scheduler's denial-of-service checks did not work
 259           properly with IPv6 addresses (STR #1134)
 260         - The lp and lpr commands did not error out properly when
 261           they were unable to write to a temporary file (STR
 262           #1129)
 263         - The pstops filter did not handle Adobe-specific
 264           comments in Windows NT driver output (STR #1085)
 265         - "lpstat -l -p" incorrectly reported the printer
 266           interface (STR #936)
 267         - The web interface now operates exclusively with the
 268           UTF-8 encoding, and sends the appropriate character set
 269           and header information to the web browser (STR #919,
 270           STR #1007)
 271         - Added a "set allowed users" interface to the web
 272           interface so that you can set the list of allowed or
 273           denied users/groups for a printer or class.
 274         - Disallow the "#" character in printer names, since it
 275           has special meaning in the shell, config files, and in
 276           URIs (STR #917, STR #1202)
 277         - Added a new application/x-csource MIME type, and
 278           support for it to the texttops filter so that you can
 279           pretty print plain text files without the C/C++
 280           keywords being highlighted.
 281         - The pdftops filter did not compile with GCC 4.0 (STR
 282           #1226)
 283         - The texttops filter did not highlight preprocessor
 284           directives followed by a tab properly.
 285         - HP PJL output now uses both JOB DISPLAY and RDYMSG
 286           commands to show the current job on the printer's
 287           display (STR #1218)
 288         - Local authentication certificates are now stored in
 289           /var/run/cups/certs by default instead of
 290           /etc/cups/certs (STR #1211)
 291         - Backends now use "&" to separate options in device
 292           URIs; "+" is still recognized but is deprecated (STR
 293           #842)
 294         - The USB backend no longer supports the usb:/dev/foo
 295           format on systems that support device ID queries.
 296         - Forced classification markings did not work when the
 297           job-sheets parameters were "none,none".
 298         - "lpstat -l -p" incorrectly showed all users as allowed,
 299           even if the queue was restricted to certain users (STR
 300           #801)
 301         - The scheduler now automatically detects SSL/TLS clients
 302           without using the SSLPort/SSLListen directives.
 303         - The CUPS API and scheduler no longer support SSLv2-
 304           encrypted connections.
 305         - Updated the cupsaddsmb utility to correctly export the
 306           CUPS driver for Windows.
 307         - Fixed a signal-handling bug in httpRead() which
 308           ultimately caused the server to print multiple copies
 309           when it was busy (STR #1184)
 310         - The cupsFile API now uses the O_APPEND option when
 311           opening files in append mode (STR #990)
 312         - The md5.h header and md5_* functions are now officially
 313           private and have been renamed to avoid conflicts with
 314           other implementations with the same name.
 315         - The pdftops filter incorrectly embedded some Type1
 316           fonts (STR #1093)
 317         - The scheduler didn't detect a closed connection in the
 318           middle of an IPP request (STR #1153)
 319         - The scheduler could block trying to read the job status
 320           if there was input pending and the job was cancelled in
 321           the same input cycle (STR #1157)
 322         - The scheduler could crash when deleting a class due to
