With Plasma 5.5 a basic Wayland session is provided. Wayland is the successor of the dated X11 windowing system providing a modern approach. The system is more secure (e.g. key loggers are no longer trivial to implement) and follows the paradigm of 'every frame perfect' which makes screen tearing very difficult. With Plasma 5.4 the KDE community already provided a technology preview based on the feature set of the Phone project. With Plasma 5.5 this is now extended with more 'desktop style' usages. Important features like move/resize of windows is now supported as well as many integration features for the desktop shell. This allows for usage by early adopters, though we need to point out that it is not yet up to the task of fully replacing an X session. We encourage our more technical users to give it a try and report as many bugs as you can find.
