To begin the KDE 3.5 release cycle , I uploaded KDE 3.5 Alpha 1  to the FTP servers. We're facing some trouble that is typical for an Alpha release, but it also brings some nice KDE 3.5 features to your desktop. The easiest way to try it is the KDE 3.5 Alpha Live CD  or compile it yourself with the Konstruct  build script.
But compile it only if you have the place and the time to help with debugging it (pass --enable-debug to "configure"). Please report bugs to bugs.kde.org  and feel welcome to join the KDE Quality team  to improve its quality in general. And don't forget: it might be the last KDE 3 Alpha release you have the chance to try - don't let the chance pass by!
