SDDM is a Qt based Display Manager used by multiple desktops, but most importantly (certainly for the PlanetKDE crowd), KDE.
After a year of seemingly little activity, I've released SDDM v0.15.0
It is mostly a bugfix release with important changes, but nothing to get particularly excited about.
For full release notes please see: https://github.com/sddm/sddm/wiki/0.15.0-Release-Announcement
Now this is out, I shall be merge a huge queue of pending larger changes - hopefully we shall see 0.16 in only a few months.
