  40           rastertolabel (a symlink is installed so that existing
  41           queues continue to work) and now also supports Zebra's
  42           CPCL language.
  43         - The lpstat command could show the wrong active job for
  44           a printer (STR #1301)

  75           attribute to localize banner pages (STR #386)
  76         - The scheduler now returns the address that was used to
  77           connect to it (STR #1076)

 103           #281)
 104         - The pdftops filter produced large output when rendering
 105           PDF files containing lot of repeated images (STR #327)
 106         - The pdftops filter now minimizes print processing of
 107           PDF files when using the page-ranges option (STR #273)

 112           and USB backends (STR #1252)
 113         - The parallel and USB backends now treat a "no space
 114           available" error as an out-of-paper condition (STR
 115           #1225)
 116         - The "lpc" command now supports the "status all" command
 117           (STR #1004)

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

 252           consistent.
 253         - Added new cupsRasterInterpretPPD() function for RIP
 254           filters to setup the raster page header from
 255           PostScript commands in a PPD file.
 256         - The CUPS browsing protocol now offers a "delete" bit
 257           to remove printers as soon as they are deleted on the
 258           server or as soon as the server shuts down gracefully
 259           (STR #793)
 260         - The CUPS_SERVER and ServerName directives (client.conf
 261           and ~/.cupsrc) may now contain names of the form
 262           "server:port" and "/path/to/domain/socket".

 268           administrator to add printer URI options to the browse
 269           URI, e.g. "encryption=required" (STR #732)
 270         - Added BrowseRemoteOptions directive to allow the
 271           administrator to add standard URI options to the
 272           remote printer URI, e.g. "encryption=required" (STR
 273           #732)
 274         - Now put "-I.." compiler option in front of all others
 275           to ensure that local CUPS headers are used before
 276           installed headers (STR #437)
 277         - New cupsLangPrintf() and cupsLangPuts() for localized
 278           interfaces.
