Plasma 5.2 Is Beautiful and Featureful (KDE.News)
We are a bit late in noting that KDE has released Plasma 5.2 on January 27. This KDE.News article gives a tour of the desktop that will be featured in upcoming Kubuntu and Fedora KDE spin releases (and probably other distributions as well). There are lots of new features and bug fixes in the release, see the changelog for all the details. "In the screen locker we improved the integration with logind to ensure the screen is properly locked before suspend. The background of the lock screen can be configured. Internally this uses part of the Wayland protocol which is the future of the Linux desktop.

There are improvements in the handling of multiple monitors. The detection code for multiple monitors got ported to use the XRandR extension directly and multiple bugs related to it were fixed."
