Mint team released new version 3.2 of Cinnamon with new features and bugs fixes, rich settings to enhance desktop using Cinnamon Control Center. In version 3.2, and similar to MATE or Xfce, Cinnamon is an entire desktop environment built on GNOME technologies. It still uses tool-kits and libraries such as GTK or Clutter and it is still compatible with all GNOME applications, but it no longer requires GNOME itself to be installed. It now communicates directly with its own backend services, libraries and daemons: cinnamon-desktop, cinnamon-session and cinnamon-settings-daemon.
