Facebook this morning released an update to its Facebook Connect JavaScript SDK that includes basic XFBML support and an optimization layer for FQL queries. Developers interested in building Connect JavaScript apps with XFBML for simpler rendering of Facebook elements will now be able to do so with just a few lines of code.

Separately, Facebook’s David Recordon announced that a prototype implementation for the OAuth WRAP specification for FriendFeed has shipped. Facebook is working to move Connect over to OAuth over the next year. Bret Taylor has posted a few notes on his blog as well.
