New features in 13.04
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.
