KDE4 has been released and available for download. KDE is a powerful graphical desktop environment for Unix and Linux workstations. It is based on the version 4 series of Qt (a cross-platform GUI application development framework).
From the announcement page:
The KDE Community is thrilled to announce the immediate availability of KDE 4.0. This significant release marks both the end of the long and intensive development cycle leading up to KDE 4.0 and the beginning of the KDE 4 era. It will contain a new multimedia API, called Phonon, a device integration framework called Solid and a new style guide and default icon set called Oxygen. It will also include the new desktop and panel user interface tool, called Plasma, which will have support for desktop widgets, similar to SuperKaramba or Apple’s Dashboard widgets.
The KDE 4.0 Visual Guide provides a quick overview of various new and improved KDE 4.0 technologies. Illustrated with many screenshots, it walks you through the different parts of KDE 4.0 and shows some of the exciting new technologies and improvements for the user.
