KDE 4.0.0 has been released onto the world. “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.” KDE 4.0 is the first release of “KDE 4”, but take note that the developers have clearly stated that KDE 4.0 is not KDE 4, but more of a base release with all the underlying systems ready to go, but with still a lot of work to be done on the user-visible side. Download it from the KDE 4.0 info page. Update: Screenshots.
