As in my usual party-pooping of Unity release surprises;
http://docs.unity3d.com/Documentation/ScriptReference/40_history.html
Looks like its close to release (or an error).
It was released almost a week ago.

Not 4.1.0f4 but 4.1.1 Eric 
(also, I made an error posting it here, should be in gossip. Sorry about that)
I would smell a typoe here since 4.1 is not listet.
I looked at the doc when 4.1.0 was released and the changes were half of those listed now. And it was indeed 4.1.0 when I looked at it last week.
