Currently, there are only 4 supported releases (Hardy, Lucid, Maverick, and Natty) and a single development release (Oneiric, slated for October 2011 release). As I said early on in the experiment, I'll stick to CD-based upgrades. The only exception I've made so far was the upgrade to Hardy due to a number of problems faced with just about every available offline upgrade method.
Let's see how well the upgrade to Karmic goes.
