Few major pieces of free software are more eagerly awaited than KDE 4. With changes to everything from the core libraries and window manager to the look, feel and function of the desktop, by any standard, KDE 4 is an extreme makeover of the popular desktop environment. Scheduled for release in October, KDE 4 can be toured now in the first beta that was released at the start of August. On the way, you'll find major overhauls of general functionality,as well as both major and minor refitting of familiar KDE programs and the introduction of a few new ones.
