Yes we are running 2013 at the moment on two Flames one Inferno and a couple of Flares. Seems stable for the most part except desktop proxies keep getting corrupted. This doesn't effect the clip proxies just the proxies on the desktop. Seems common across all the desktop machines. No solution apart from restart the software. We have had this update for a couple of weeks and are quite confident with it.
