Below document provides most used , and most noticeable changes
*The web-interface has been given a new look , using php-cgi and not php.
*The new interface provides more improvements to add and modify printer configuration
*The Administration page provides more advanced operations like share, unshare, provides list of backends to choose from
IPP Support
*CUPS now conforms to the draft IPP/2.0 and IPP/2.1 specifications
*CUPS supports the operation of downloading of files from print job using the "CUPS-Get-Document Operation"
*The scheduler and backend discovery interface support a device-location attribute where we can specify the location of the printer
*Support of hold jobs and releasing of jobs on hold
* CUPS now uses "Bonjour (DNS-SD)" providing mDNS(multicast DNS) which supports Bonjour-based printer discovery
*Better Access control by providing support for adding multiple addresses in Allow and Deny lines, and now returns HTTP 403 (forbidden)<br>
for user who authenticates successfully , but doesn't have access to perform the operation
*Scheduler now supports an AccessLogLevel directive to control what is logged in the access_log file.  There are 3 levels
    config; Log when printers and classes are added, deleted, or modified and when configuration files are accessed or updated.
    actions; Log when print jobs are submitted, held, released, modified, or canceled, and any of the conditions for config.
    all; Log all requests.
    The default access log level is actions.
*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
*Scheduler now supports ErrorPolicy that can be defined in printers.conf,  and now supports retry-current-job policy, that retries the current job immediately
*the scheduler now sets more PAM attributes to better support third-party authentication schemes.
*scheduler now coalesces configuration and state file changes to reduce the amount of disk activity and caches printer attributes to further reduce startup time.
*scheduler now starts the notifier for RSS subscriptions after creation so the feed is available immediately.
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.
*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.
*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 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
