Not too many changes on the shipped applications or user interface. It's really the same set of applications we've seen in the past few releases. On the one hand, it's a sign of stability; and on the other, dare I say that Ubuntu is becoming...boring?
The few tweaks that there are happened in the System->Administration menu. A new application, Computer Janitor, has been added.

Computer Janitor is supposed to clean up unnecessary files. That's the description on its About page, anyway. While it's a welcome addition, it doesn't look to be anything earthshaking.
