Cairo-Dock is back after a decade hiatus! From the early 2010's you may remember Cairo-Dock / GLX-Dock as a complementary dock for your Linux desktop. The last time writing about it was the Cairo-Dock 3.4 release in 2014 when it was working toward EGL/Wayland support. Since then it was rather inactive the past decade besides a small 3.5 update one year ago with a few fixes. But out this week is now Cairo-Dock 3.6 with the long-awaited port to Wayland, HiDPI display handling, and other improvements...
