MATE 1.20 released

The theme for this release has been stabilising the MATE Desktop by replacing deprecated code and modernising large sections of the code base. Weive also improved our window manager (Marco) and added support for HiDPI. Along the way weive fixed hundreds of bugs. Squished iem dead!GNOME 2 is, in my view, one of the best desktop environments ever created, and surely the best desktop environment ever made on Linux. It was consistent, reasonably fast, had a lot of great, high-quality themes, stayed out of your way, and struck a decent balance between configurability and ease of use. Ever since GNOME 2, I've been sorely disappointed with the Linux desktop environments.MATE is a godsend.
