Adium 1.4.3 is now available. For the full list of changes and all the gory details see the release notes.

Here are a few of the more prominent changes:

Facebook Chat
Facebook will now connect via the officially-sanctioned mechanism (Facebook page on the API).  You no longer have to provide Adium with your username and password; when you first log in, you will be prompted to authenticate via a facebook.com window. Existing Facebook Chat accounts are upgraded automatically.

MSN
We reverted Adium 1.4.2’s change to libpurple’s MNP16 support from MSNP15. This should fix direct file transfers, user icons, and receiving custom emoticons, while disabling multiple points of presence (MPOP). We determined that this was the better trade-off based on user feedback.

Other important changes
We also fixed Twitter connectivity for many, a common crash, and activated the overlay scrollers for Lion.
