It's Ubuntu 9.10 release day! Check out the main page, or just head over and download it. I've been running the RC and Beta at home, and other than it being on an under powered computer, There's tour of features, and also Lifehacker previously had a look at the beta and has a nice article on the updates it's gotten from the 9.04 version as well as a lovely screenshot gallery.
Congrats to the Ubuntu team on another fine release! I'm really looking forward to the (rumored) big changes (ie: more revolutionary and less evolutionary) coming in the 10.04 LTS release of Lucid Lynx. This will (in theory) have the new GNOME 3.0 software which will make it a revolutionary release (or at least, not just some tweaks in GNOME).
