KDE Plasma 5.19 Beta Thursday, 14 May 2020. It's time to test the beta release for Plasma 5.19! In this release, we have prioritized making Plasma more consistent, correcting and unifying designs of widgets and desktop elements; worked on giving you more control over your desktop by adding configuration options to the System Settings; and improved usability, making Plasma and its components easier to use and an overall more pleasurable experience.
