Well you are a first. Someone who is willing to work a little. PM me if there is any issue at all. I will personally log into your shard to check things out and make code fixes for you if need be.
I think the notes say, but there are a couple of known quirks. I've seen it misbehave with Razor (fixed... I think) and because of the optimization algorithm there are chances of seeing what you are not supposed to see when you are standing in a corner. I.e., if you are inside a house, in the corner, you may sometimes see "thru" the corner and outside of the house, in a few funny places. There is no fix for this that offers performance, so there will be no fix.
