KDE Software Compilation 4 (KDE SC 4) was the only series of the so-called KDE Software Compilation (short: KDE SC), first released in January 2008 and the last release being 4.14.3 released in November 2014.[1][6] It was the follow-up to K Desktop Environment 3. Following KDE SC 4, the compilation was broken up into basic framework libraries, desktop environment and applications, which are termed KDE Frameworks 5, KDE Plasma 5 and KDE Applications, respectively.

Major releases (4.x) were released every six months, while minor bugfix releases (4.x.y) were released monthly.[7]

The series included updates to several of the KDE Platform's core components, notably a port to Qt 4. It contained a new multimedia API, called Phonon, a device integration framework called Solid and a new style guide and default icon set called Oxygen. It also included a new, unified desktop and panel user interface called Plasma, which supported desktop widgets, replacing K Desktop Environment 3's separate components.

One of the overall goals of KDE Platform 4 was to make it easy for KDE applications to be portable to different operating systems. This was made possible by the port to Qt 4, which facilitated support for non-X11-based platforms, including Microsoft Windows and Mac OS X. Versions 4.0 to 4.3 of KDE Software Compilation were known simply as KDE 4 – the name change was a component of the KDE project's re-branding to reflect KDE's increased scope.
