Highlights of the KDE Plasma 5.16 desktop environment include a totally revamped notifications system that now offers a Do Not Disturb mode, support for critical notifications in full-screen apps, improved notifications for file transfer operations, a more intelligent history with support for grouped notifications by app, and better configuration options in System Settings. The login, lock, and logout screens were improved as well in KDE Plasma 5.16 with a new hover behavior, new icons and labels, as well as support for adjusting the login button layout. Work on the Wayland support continues as well with this release, which adds the ability to use the Nvidia proprietary graphics drivers under the Wayland session.
