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.
This is a substantial release that’s pretty much a must for every KDE user. I can’t wait until Wayland can truly be used as the default, and I feel that moment is actually quite, quite close now.
