Vbulletin 4.0 and Facebook Connect Question

[paintballer.ie]

I currently am running 3.8 and noticed that fb is not on vbulletin.com here.

1. Is this now part of vb as standard?
2. Is it stable?
3. Is it the same as the fbconnect mod that was out on .org for a while now?

[ENF]

1. It's now included it VB from 4.0.3 onward. Except, Facebook Connect itself is going away and is being replaced with a new connect method. (Done by Facebook themselves, not vb)
2. The current one in 4.0.3 works fine. (I personally still prefer the modification provided over at vbulletin.org)
3. It's not the same as the modification seen on vbulletin.org -- The current implemented version in 4.0.3 is just connect only, no other additional features. More features will be introduced later.

Hope this helps.
