It's a Linux release. Basically it updates the base image to include all of the latest versions of things from the last six months. If you really wanted to see everything that changed, you could do a diff of http://packages.ubuntu.com/maverick/allpackages http://packages.ubuntu.com/maverick/allpackages and whatever release you are running. But yes; this release is just a cleaned up version of the previous release with updated versions of all of the internal parts. But in my mind, that's all I really want, and I am very glad Ubuntu is still updating regularly.
