   5
   6         - Options in PPD files are no longer automatically put in
   7           an "Extra" group; rather, all options that are not

  11           uniquely identifies a job on a network (STR #1410)
  12         - The init script now unsets the TMPDIR environment
  13           variable to prevent user temporary directories from

  48         - The rastertodymo driver has been renamed to
  49           rastertolabel (a symlink is installed so that existing
  50           queues continue to work) and now also supports Zebra's
  51           CPCL language.
  52         - The lpstat command could show the wrong active job for
  53           a printer (STR #1301)

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

  89         - Added support for the GCC position independent
  90           executable options (STR #1209)
  91         - Added new BrowseLocalProtocols and
  92           BrowseRemoteProtocols directives to cupsd.conf,

 112           #281)
 113         - The pdftops filter produced large output when rendering
 114           PDF files containing lot of repeated images (STR #327)
 115         - The pdftops filter now minimizes print processing of
 116           PDF files when using the page-ranges option (STR #273)

 121           and USB backends (STR #1252)
 122         - The parallel and USB backends now treat a "no space
 123           available" error as an out-of-paper condition (STR
 124           #1225)
 125         - The "lpc" command now supports the "status all" command
 126           (STR #1004)

 129         - The "make test" script now creates the test files in
 130           "/tmp/cups-$USER" instead of "/tmp/$USER" (STR #981)
 131         - All backends now abort on error when printing a job to
 132           a class - this allows the next printer in the class to
 133           print the job (STR #1084)
 134         - The scheduler now verifies that a printer supports
 135           Letter or A4 media sizes before setting them as the
 136           initial default (STR #1250)
 137         - The cupstestppd program now flags bad Resolution
 138           options (STR #1269)
 139         - The USB backend now retries printing when the printer
 140           is disconnected or turned off (STR #1267)
 141         - Added new httpGetHostname() function to CUPS API, and
 142           use it instead of gethostname() so that the web
 143           interface will work correctly on systems whose hostname
 144           is not the FQDN (STR #1266)
 145         - The scheduler now stops printers if the backend for the
 146           queue is missing on startup (STR #1265)
 147         - The configure script now supports "--disable-library"
 148           to disable particular image file format support
 149           libraries, even if they are available on the build
 150           system (STR #1248)
 151         - The IPP backend did not always report on the total
 152           number of pages that were printed (STR #1251)
 153         - The lpstat program could display garbage date and time
 154           values for locales whose date format exceeded 31
 155           characters (STR #1263)
 156         - The cupstestppd program would segfault when testing
 157           certain broken PPD files (STR #1268)
 158         - Dramatically reduced the overhead of implicit classes.
 159         - Added new cupsDir*() functions to CUPS API.
 160         - Printers can now be published individually for sharing.
 161         - Fixed a bug in the scheduler's startup signalling code
 162           which caused cupsd to send the SIGUSR1 signal to the
 163           init process instead of the original parent process
 164           (STR #1258)
 165         - Added new on-line help CGI to web interface to provide
 166           searchable help.
 167         - Devices are now tracked dynamically, with each query
 168           doing a new device scan.  This eliminates a previous
 169           startup delay caused by slow backends and allows new
 170           printers to be seen without restarting the server,
 171           however it limits the amount of device URI checking
 172           that can be done (basically now the scheduler only
 173           requires a URI with a method that is a listed backend)
 174         - Added new printer auto-detection, server configuration,
 175           and log file viewing to the administration web page.
 176         - Added new "set allowed users" web interface to set the
 177           list of allowed users for a printer or class.
 178         - The scheduler, command-line, and web interfaces now
 179           limit the list of printers and classes to those
 180           accessible by a user.
 181         - cupsMarkOptions() now handles more non-standard
 182           duplexing options and choices (STR #915)
 183         - cups-lpd now honors remote banner requests with the
 184           "standard" banner whenever a printer does not have one
 185           defined (STR #1220)
 186         - The scheduler's denial-of-service checks did not work
 187           properly with IPv6 addresses (STR #1134)
 188         - The lp and lpr commands did not error out properly when
 189           they were unable to write to a temporary file (STR
 190           #1129)
 191         - The pstops filter did not handle Adobe-specific
 192           comments in Windows NT driver output (STR #1085)
 193         - "lpstat -l -p" incorrectly reported the printer
 194           interface (STR #936)
 195         - The web interface now operates exclusively with the
 196           UTF-8 encoding, and sends the appropriate character set
 197           and header information to the web browser (STR #919,
 198           STR #1007)
 199         - Added a "set allowed users" interface to the web
 200           interface so that you can set the list of allowed or
 201           denied users/groups for a printer or class.
 202         - Disallow the "#" character in printer names, since it
 203           has special meaning in the shell, config files, and in
 204           URIs (STR #917, STR #1202)
 205         - Added a new application/x-csource MIME type, and
 206           support for it to the texttops filter so that you can
 207           pretty print plain text files without the C/C++
 208           keywords being highlighted.
 209         - The pdftops filter did not compile with GCC 4.0 (STR
 210           #1226)
 211         - The texttops filter did not highlight preprocessor
 212           directives followed by a tab properly.
 213         - HP PJL output now uses both JOB DISPLAY and RDYMSG
 214           commands to show the current job on the printer's
 215           display (STR #1218)
 216         - Local authentication certificates are now stored in
 217           /var/run/cups/certs by default instead of
 218           /etc/cups/certs (STR #1211)
 219         - Backends now use "&" to separate options in device
 220           URIs; "+" is still recognized but is deprecated (STR
 221           #842)
 222         - The USB backend no longer supports the usb:/dev/foo
 223           format on systems that support device ID queries.
 224         - Forced classification markings did not work when the
 225           job-sheets parameters were "none,none".
 226         - "lpstat -l -p" incorrectly showed all users as allowed,
 227           even if the queue was restricted to certain users (STR
 228           #801)
 229         - The scheduler now automatically detects SSL/TLS clients
 230           without using the SSLPort/SSLListen directives.
 231         - The CUPS API and scheduler no longer support SSLv2-
 232           encrypted connections.
 233         - Updated the cupsaddsmb utility to correctly export the
 234           CUPS driver for Windows.
 235         - Fixed a signal-handling bug in httpRead() which
 236           ultimately caused the server to print multiple copies
 237           when it was busy (STR #1184)
 238         - The cupsFile API now uses the O_APPEND option when
 239           opening files in append mode (STR #990)
 240         - The md5.h header and md5_* functions are now officially
 241           private and have been renamed to avoid conflicts with
 242           other implementations with the same name.
 243         - The pdftops filter incorrectly embedded some Type1
 244           fonts (STR #1093)
 245         - The scheduler didn't detect a closed connection in the
 246           middle of an IPP request (STR #1153)
 247         - The scheduler could block trying to read the job status
 248           if there was input pending and the job was cancelled in
 249           the same input cycle (STR #1157)
 250         - The scheduler could crash when deleting a class due to
 251           infinite recursion.
 252         - Updated the Zebra ZPL label printer driver to use the
 253           run-length encoding and support more options.
 254         - Updated serial backend to scan for /dev/ttyC* as well
 255           as /dev/ttyc* for Cyclades serial ports (STR #1049)
 256         - The scheduler could hang reading the job status under
 257           certain circumstances (STR #1068)
 258         - The USB backend termination signal code was inverted
 259           (STR #1046)

 261           consistent.
 262         - Added new cupsRasterInterpretPPD() function for RIP
 263           filters to setup the raster page header from
 264           PostScript commands in a PPD file.
 265         - The CUPS browsing protocol now offers a "delete" bit
 266           to remove printers as soon as they are deleted on the
 267           server or as soon as the server shuts down gracefully
 268           (STR #793)
 269         - The CUPS_SERVER and ServerName directives (client.conf
 270           and ~/.cupsrc) may now contain names of the form
 271           "server:port" and "/path/to/domain/socket".

 277           administrator to add printer URI options to the browse
 278           URI, e.g. "encryption=required" (STR #732)
 279         - Added BrowseRemoteOptions directive to allow the
 280           administrator to add standard URI options to the
 281           remote printer URI, e.g. "encryption=required" (STR
 282           #732)
 283         - Now put "-I.." compiler option in front of all others
 284           to ensure that local CUPS headers are used before
 285           installed headers (STR #437)
 286         - New cupsLangPrintf() and cupsLangPuts() for localized
 287           interfaces.
