The Open Source GUI was supposed to be available in the middle of December, but the KDE Release Team has decided to release KDE 4.0 it in January.
The release has a couple of essential issues which need to be fixed before it is released, including the crucial visual appearance. There is also a bug in certain codecs of xine that cut off audio fragments prematurely.
The developers say that the KDE Development Platform and a lot of applications are considered stable and quite usable. The developers are confident to be able to release a more polished and better working KDE 4.0 desktop in January. The changed plans involve releasing on January 11th, 2008.
