The latest version is 3.0.0.2.9, I still have 3.0.0.2.3
just noticed that I too need to update. You can get the latest version at
http://www.alice.org/3. I have noticed that the version on the Project Kenai page is not the latest, also all references to the Kenai page have been removed on the Alice 3 page.
Hope this helps!
