Cups, wat een afkorting is voor Common Unix Printing System, is een opensourceprintsysteem voor OS X, Linux en Unix-achtige besturingssytemen. Het ondersteunt onder meer het Internet Printing Protocol (ipp) voor afdrukken zonder drivers. Daarnaast is er ondersteuning voor de Line Printer Daemon (lpd), Server Message Block (smb), AppSocket (JetDirect) en drivers die als ppd-bestanden worden gedistribueerd. Cups bestaat inmiddels alweer vijftien jaar en nu is versie 2.0 uitgekomen. Hierin is onder meer de beveiliging van de scheduler verbeterd, is ondersteuning voor systemd, het verifiëren van tls-certificaten en policy enforcement toegevoegd, en is OpenSSL vervangen door GNU TLS.
CUPS 2.0.0CUPS 2.0rc1
- The scheduler did not preserve listener sockets from launchd or systemd after a restart (<rdar://problem/18112848>)
- Added some USB quirk rules for the libusb-based USB backend (STR #4482)
- Spanish localization update (STR #4487)
- Updated documentation for 2.0.0 release.
CUPS 2.0b1
- Documentation updates (STR #4464)
- The scheduler now monitors the AC power status on OS X, allowing for "sleep printing" when sharing printers (<rdar://problem/17325852>)
- The scheduler incorrectly called launch_activate_socket multiple times on OS X (<rdar://problem/17523218>)
- The ippserver test program now passes the IPP Everywhere self- certification tests (STR #4101)
- Relaxed the new OS X filter sandbox slightly (STR #4471, <rdar://problem/17483959>)
- Dropped the old Epson Stylus Color/Photo sample drivers since they don't work with any current printers and there are free alternatives that produce much better output (<rdar://problem/18036889>)
- Log and configuration files that are not world-readable are again accessible via the web interface (STR #4461)
- PPD files are now created using the permissions specified by the ConfigFilePerm directive.
- Fixed RPM build issues (STR #4459)
- Fixed the spinner image and restart page when reconfiguring the scheduler through the web interface (STR #4475)
- Added a "--list-filters" option to the cupsfilter command (STR #4325)
- Added systemd support (STR #3917)
- Added support for re-sending a job as a raster file if a higher-level format such as PDF fails (<rdar://problem/15583721>)
- Added support for regular expression matching in the MIME type rules (<rdar://problem/11131245>)
- Added support for TLS certificate validation and policy enforcement (STR #1616)
- Added support for simultaneous XML and test output from ipptool.
- Added support for PAUSE directive in ipptool test files.
- Added support for auto-typing of TIFF files by ipptool (STR #4418)
- The scheduler now returns completed jobs in the correct newest-to- oldest order (STR #4396)
- The configure script now supports target-specific tools for pkg-config and others (STR #4423)
- The ipptool program now supports EXPECT statements for collection member attributes (<rdar://problem/15355218>)
- The ipptool program now supports collection attributes with multiple values (<rdar://problem/15355124>)
- The sample drivers now include all of the installed localizations by default (<rdar://problem/14756625>)
- Adopted Linux man page conventions and updated all man pages (STR #4372, STR #4329)
- The scheduler now supports the "first-index" operation attribute for the Get-Jobs operation (STR #2913)
- Changed the default AccessLogLevel and PageLogFormat to disable the access_log and page_log files by default (<rdar://problem/16495000>)
- cupsRasterInterpretPPD now supports the Orientation header in order to support long-edge feed raster printers (<rdar://problem/15837926>)
- The scheduler now allows run-as-root backends to have group read and execute permissions (STR #2935)
- The ippFindAttribute and ippFindNextAttribute functions now support hierarchical searches (STR #4395)
- Dropped OpenSSL support in favor of GNU TLS.
- Dropped "dark wake" support on OS X, which was preventing portables from going to sleep when there was a stuck job. We now use a variation of the CUPS 1.4 sleep support to do a cleaner sleep (<rdar://problem/14323704>)
- Dropped support for AIX, HP-UX, and OSF/1 (aka Digital UNIX)
- Dropped lppasswd and support for Digest authentication in in the scheduler (STR #4321)
- The cupsGetClasses, cupsGetPrinters, and cupsTempFile functions are no longer supported.
- The scheduler now caches more job history data and limits the number of completed jobs returned by Get-Jobs as needed in order to prevent a denial-of-service on busy servers (STR #2913)
- The filter/backend sandbox on OS X now defaults to a more strict whitelist (<rdar://problem/15939788>)
- Increased the default idle exit timeout to 60 seconds on OS X (<rdar://problem/16041820>)
- Printer classes were not accessible on OS X (<rdar://problem/16385643>)
- The scheduler now uses </DefaultPrinter> to close the default printer definition in printers.conf (STR #4153)
- Canceling all jobs in the web interface now just cancels the jobs (STR #1914)
