Updated Packages
As with every new release, packages--applications and software of all kinds--are being updated at a rapid pace. Many of these packages came from an automatic sync from Debian's unstable branch; others have been explicitly pulled in for 13.04
Raring Ringtail
For a list of all packages being accepted for 13.04 Raring Ringtail, please subscribe to raring-changes.
Linux kernel 3.8.8
Ubuntu 13.04 includes the 3.8.0-19.29 Ubuntu Linux kernel which was based on the v3.8.8 upstream Linux kernel.
Unity 7
Unity 7 brings a lot of performance improvements, reduced memory consumption and a great number of small UI fixes to bring a better overall shell experience. Those are like being typo-tolerant in the dash when searching for an application, using the mouse scroll wheel on a launcher icon to switch between applications or better available third party devices handling. You will notice as well some new icons themes to continue on lead of bringing design as the central Ubuntu experience.
You will notice that only one workspace is available by default on any new installation. If you want to bring back workspaces, you can find an option in the Appearance panel of System Settings under the Behavior tab. You can as well enable "Show desktop" button on the Launcher.
Upstart 1.8
This release provides a new bridge, the upstart-file-bridge(8) that allows jobs to react to filesystem changes. For example, to have a job start when a particular file is created:
start on file FILE=/var/log/foo.log EVENT=create
Or to start a job when a file matching a glob pattern is deleted:
start on file FILE=/var/app/*.foo EVENT=delete
See upstart-file-bridge(8) and file-event(7) for further details.
Additionally, a new upstart-monitor(8) tool is available that allows event flows to be observed in real-time. This tool can run as a graphical or console application.

CUPS 1.6.2 and cups-filters 1.0.34
We had already switched to CUPS 1.6.x in Quantal (12.10) but had to apply a huge, awkward Ubuntu-specific patch to avoid regressions. Now we are up to all new standards without needing to do anything Ubuntu-specific.
Most important change here is the way how network printing works. Formerly, a CUPS-specific mechanism was used. The server broadcasted information about the printers it shares and the clients listen to these broadcasts making the printers available on the client side, looking like local print queues for the applications.
Recently, the Printer Working Group (PWG), an association of printer and software industry for developing standards related to digital printing, has created a standard for broadcasting information about shared printers. This standard is broadcasting the information via Bonjour, a protocol also used for many other network services, like shared files systems, screens, music/video servers, ...
CUPS has adopted this standard in 1.6.x, but only broadcasts and does not listen to broadcasts of CUPS daemons (or generally print servers using Bonjour) on other machines, letting remote printers not automatically get available locally. CUPS also dropped the old broadcasting protocol without transition period.
To overcome the problems and keeping network printing as easy as before (this is why 10 years ago the distros switched to CUPS) the cups-filters project of OpenPrinting introduced cups-browsed, an extra daemon which by default listens to Bonjour broadcasts of remote CUPS daemons (of IPP printers coming soon) and automatically creates local print queues pointing to the shared printers making pure CUPS 1.6.x networks working out-of-the-box.
If your network still contains machines running CUPS 1.5.x and older, cups-browsed also has legacy support for the old CUPS broadcasting, browsing (listening), and BrowsePoll. Please see the comments in /etc/cups/cups-browsed.conf, edit the file appropriately, and restart cups-browsed ("sudo restart cups-browsed") or reboot. When upgrading to Raring, BrowsePoll directives are overtaken from CUPS to cups-browsed automatically.
For everyone developing embedded or mobile systems based on Ubuntu, the CUPS package is split up into more binary packages to get a minimum client-only printing stack, of the packages cups-daemon, libcups2, and cups-browsed, occupying only ~1 MB. This only listens for Bonjour broadcasts (legacy CUPS broadcasts and BrowsePoll optional) of remote CUPS servers and makes the printers available locally. No drivers and filters for locally connected printers are available then.
Another thing to mention which was available before but never told about in release notes: When sharing local printers they are automatically available also for Apple's iOS devices (iPhone, iPad, iPod touch).
Python 3.3
We eventually intend to ship only Python 3 with the Ubuntu desktop image, not Python 2. The Ubuntu 13.04 image continues this process, although we will not be able to convert everything to Python 3 for Ubuntu 13.04 final image.
If you have your own programs based on Python 2, fear not! Python 2 will continue to be available (as the python package) for the foreseeable future. However, to best support future versions of Ubuntu you should consider porting your code to Python 3. Python/3 has some advice and resources on this.
