The highly anticipated new version of TeamSpeak has reached the open beta phase - interested users can now
download the TeamSpeak 3 client to check out the new features.
The official site has been smashed and is thoroughly offline (probably because of their default policy of not allowing redistribution of their download client, perhaps? Linking off Rapidshare is the best option you could come up with? REALLY?!) so I can't point you to a list of the new features, but it is a total rewrite from the ground up and boast a whole stack of changes.
