It's been almost two years since the announcement of the Cinnamon project (January 2012) and now the GNOME fork reached version 2.0.0 in Git this morning (2.0.1 was also subsequently tagged after a change for applet context menus). With the current Cinnamon release, version 1.8, having come out in early May there's been a lot of changes made in the past few months.
Cinnamon 2.0 will premiere on LinuxMint 16 that's due out next month and lives under the "Petra" codename. In digging through Git and with the help of the internal Anzwix, among the changes are a new launcher/desktop-file editor (Cinnamon-Desktop-Editor), support for the Tomahawk and SMPlayer media players, sound changes, new applet work, a new admin category for Cinnamon Settings, new key-bindings, a new snap/tile on-screen-display pop-up, web-camera support for Cinnamon Settings, new Cinnamon translations, and numerous bug-fixes.
As soon as an official release announcement/overview is made, we'll be back with more coverage of Cinnamon 2.0 and more thoroughly cover the primary features of this new Linux desktop release ahead of LinuxMint 16.
