====Networking====
* CUPS now uses "Bonjour (DNS-SD)" providing mDNS(multicast DNS) which supports Bonjour-based printer discovery
 
====Scheduler====
 
*Scheduler now adds "authenticated" policy, So that certain IPP operations can be authenticated.On Fedora-11 the default policy is "default"
The scheduler provides "OpPolicy" directive which can be used to modify the policy.  lpadmin command can also be used to set the policy to<br>
a particular printer using <code>-o printer-op-policy</code>
*the default LogLevel is now "warn" instead of "info"
*The scheduler now supports a DefaultPaperSize directive to override the default paper size defined by the locale or libpaper configuration
*New ErrorPolicy "retry-current-job" is added, that retries the current job immediately
*Scheduler supports SSLOptions Directive in cupsd.conf which specifies the network address and port to Listen for secure connections
*Scheduler now supports new "FatalErrors" Directive to determine which kind of errors are fatal, The following kind of errors are currently recognized
none, all, browse, config (configuration syntax errors), log (log file creation errors), permissions (file permission errors ex: certifcate files and keys)
*Scheduler now passes hostname from the job was submitted as "job-originating-host-name" to filters and backends
*Scheduler now includes CUPS_FILETYPE, PRINTER_INFO, and PRINTER_LOCATION environment variables that is passed to filter or backend
*The scheduler now supports a test mode via the "-t" option, which can be used to test the syntax of cupsd.conf.
 
====Printer Drivers====
*USB printer support; the usb backend now uses libusb when available to allow it to better work with third-party scanning and printing solutions.
* NO, WE HAVEN'T ENABLED THAT IN FEDORA - Tim
*the cupsPJLDisplay PPD attribute controls the PJL commands used to display the current user and job on the printer.
*new generic PostScript and PCL drivers provide improved support for laser printers, the CUPS DDK drivers offer support for many HP DesignJet printers<br>
and new label drivers offer support for Seiko and Tharo label printers.
* A new CUPS command file filter for PostScript printers provides auto-configuration, self-test page, and status and supply level reporting functions.
*The CUPS DDK is now a standard part of CUPS.
 
====Filters====
*the standard image filters now support image files larger than 2GB.
*the bundled banner ("job-sheets") pages are now generated using a new banner filter provides easier customization and better support for UTF-8 text.
*the pdftops filter has been replaced with a wrapper program that runs the Xpdf, poppler, or Ghostscript PDF to PostScript utilities.
* IN FEDORA IT IS CONFIGURED TO USE POPPLER - Tim
 
===system-config-printer===
 
In this release, system-config-printer uses PolicyKit to control access to restricted CUPS functionality.
The following functions are controlled via PolicyKit policies currently:
* add/remove/edit local printers
* add/remove/edit remote printers
* add/remove/edit classes
* enable/disable printer
* set printer as default printer
