Click here to view some info from the former lead developer for this product explaining the changes.
And recently, I have been trying out Ubuntu 10.04.3 LTS. I'm waiting for the 12.04 LTS release. But in the mean time, I have this PowerPoint Presentation of Kubuntu, embedded below if you would like to catch up on some info. After that is a photo showing off their support for now.
I hope you enjoy.
