High Quality Content by WIKIPEDIA articles! The KDE Software Compilation (KDE SC) is a desktop environment and an associated range of KDE Applications produced by KDE. Prior to version 4.4, released in February 2010, the Software Compilation was known as KDE, which used to stand for K Desktop Environment until November 2009. The KDE SC includes only applications whose development teams choose to follow the Software Compilation`s release schedule; as a result, many popular KDE applications, such as Amarok and Digikam, are not part of the Software Compilation. To date there have been four series of releases.
