minor feature:
Plasma 5.1 sports a wide variety of improvements ( with over 180 bugs resolved), leading to greater stability, better performance and new and improved features.
More thorough Breeze style, also for Qt4 applications.
Popular additional widgets such as the Icons-only Task Manager, the Notes widget and the System Load Viewer make their re-entry. Support for multiple time zones has been added back in the panel's clock. The notifications have been visually improved, along with many bigger and smaller bug fixes.
Further progress has been made on Wayland support. A new window manager binary 'kwin_wayland' now complements the existing 'kwin_x11', and is equipped with the ability to start a nested X server for compatibility with X11-based applications.
