KDE Plasma 4, subsequently renamed from KDE Plasma Workspaces, is the umbrella term for the fourth generation graphical environments provided by KDE. It consists of three workspaces, each targeting a certain platform: Plasma Desktop for traditional desktop PCs and notebooks, Plasma Netbook for netbooks, and Plasma Active for tablet PCs and similar devices. With the release of KDE SC 4.11 on 14 August 2013, KDE Plasma 4 was placed into a feature freeze and turned into a long-term stable package until August 2015. On 15 July 2014 KDE Plasma 4’s successor, KDE Plasma 5, was released.
