KDE Plasma 5 is the fifth and current generation of the desktop environment created by KDE primarily for Linux systems. KDE Plasma 5 is the successor of KDE Plasma 4 and was initially released on 15 July 2014. It includes a new default theme, known as "Breeze", as well as increased convergence across different devices. The graphical interface was fully migrated to QML, which uses OpenGL for hardware acceleration resulting in better performance and reduced power consumption.
KDE Plasma 5 is built using Qt 5 and KDE Frameworks 5, predominantly plasma-framework.
Plasma 5.0 improves support for HiDPI displays and ships a converged graphical shell, able to modify the graphical shell according to the device in use. It also includes a new default theme, dubbed Breeze. Changes under the hood include the migration to a new, fully hardware-accelerated graphics stack centered on an OpenGL(ES)-based scene graph (canvas). Plasma 5 completes the migration of KDE Plasma 4 to QtQuick. Qt 5's QtQuick 2 uses a hardware-accelerated OpenGL(ES) scenegraph to compose and render graphics on the screen, which allows for the offloading of computationally expensive graphics rendering tasks onto the GPU, which frees up resources on the system's main CPU, and is faster and more power efficient.
KDE Plasma 5 uses the X Window System, but support for is under development. Initial support for Wayland was made available in the 5.4 release. Stable support for a basic Wayland session was provided in the 5.5 release (December 2015).
Since the split of the KDE Software Compilation into KDE Frameworks 5, KDE Plasma 5 and KDE Applications, each subproject can develop at its own pace. KDE Plasma 5 is on its own release schedule, with feature releases every three months, and bugfix releases in the intervening months.
