Its not yet available on Debian based distros (unless you compile from source), but I have been using it for a week or so on my Manjaro installation. Its quite a change from earlier Cinnamon versions, large improvements. The biggest change is that it is no longer dependent on Gnome.

Cinnamon Backend 2.0
Prior to version 2.0, and similar to Shell or Unity, Cinnamon was a frontend on top of the GNOME desktop.
In version 2.0, and similar to MATE or Xfce, Cinnamon is an entire desktop environment built on GNOME technologies. It still uses toolkits 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.
Better compatibility and portability
Another very tangible gain is backward compatibility and portability. Until now Cinnamon was designed to work on top of GNOME 3… a desktop which is being actively designed and features radical changes every 6 months. For instance, it is not possible to communicate with gnome-settings-daemon 3.8 the same way as with gnome-settings-daemon 3.6. The communication protocols and ABI keep changing and so a particular version of Cinnamon had to be designed to work with a particular version of GNOME.
It looks like it will come to LMDE (and then shortly thereafter to Debian proper) sometime in Decenber (or later).
This new version will be featured in Linux Mint 16 “Petra” planned for the end of November and will then be backported to LMDE and Linux Mint 13 LTS.
Cinnamon 2.0 represents 5 months of development and 856 commits from 28 developers. It features a lot of bug fixes but also brand new features and many improvements.
I really like this new Cinnamon. The window edge-snapping/tiling is impressive. The included default applets are pretty complete and new ones should come soon. Many of the old ones still work fine.
