Plasma 2 Technology Preview released http://www.osnews.com/story/27482/Plasma_2_Technology_Preview_released
Plasma 2 Technology Preview demonstrates the current development status. The Plasma 2 user interfaces are built using QML and run on top of a fully hardware accelerated graphics stack using Qt5, QtQuick 2 and an OpenGL(-ES) scenegraph. Plasma 2 is a converged workspace shell that can run and switch between user interfaces for different formfactors, and makes the workspace adaptable to a given target device.
Plasma 2 is not a complete rewrite; it's a port to a new graphics system (a fully hardware accelerated OpenGL(ES) scenegraph).
