Update KDE Plasma Desktop to 5.20.0

Everyday utilities and tools, such as the Panels, Task Manager, Notifications
and System Settings, have all been overhauled to make them more usable,
efficient, and friendlier.

Meanwhile, developers are hard at work adapting Plasma and all its bits and
pieces to Wayland. Once done, Plasma will not only be readier for the future,
but will also work better with touchscreens and multiple screens with different
refresh rates and DPIs. Plasma will also offer better support for
hardware-accelerated graphics, be more secure, and enjoy many more advantages.
Although still work in progress, 5.20 already offers users many of the benefits
of Plasma on Wayland.

Read on to find out more about the new features and improvements included in
Plasma 5.20...
