Polishlinux.org posted a preview on KDE 4
A quote from the article:
>> KDE 4 Preview
It's been an entire month since I've investigated the new K Desktop Environment, labeled called KDE 4. Honestly, I wanted to wait until Beta 3, which should have appeared on 5th October, but as you all can see, that never happened. On the IRC channel, #kde4-devel, I was informed that Beta 3'should have been tagged yesterday, but unfortunately it didn't turn out that way: not waiting for more time to pass, I made up my mind and have updated the SVN, having run already run cmake.
