As a heavily KDE leaning distribution Knoppix was also one of the first to ship with KDE 4 when it debuted, where it allowed for an early view of things to come. The DVD came with a variety of desktops including GNOME, Fluxbox and IceWM which could be enabled through entering cheat codes at the boot prompt. These days, ever since 6.0 was released, LXDE has become the default on the CD, with more environments and window managers available on the DVD.
Besides, Klaus Knopper also issues special versions to coincide with the annual CeBIT and LinuxTag expos and conventions, so there are usually three releases a year to keep the system up to date with the ever changing requirements of hardware detection.
