I just upgraded my Kubuntu to Fiesty Fawn Herd 4 which was released yesterday. Some nice updated features and for an alpha release it runs suprisingly stable.

My favourite feature so far is being able to assign static IP information to a connection using Network Manager.

Looking forward to the final of this release!

Update: I have a new feature that is most welcomed. That is the addition of proprietary drivers in the repositories. More specifically the ATI drivers. Their default installer was always a nuisance and never compiled properly. However as of today I have the latest driver with OpenGL working fully and hardware acceleration is working too.
