In case you missed the 1,000s of other posts you can find it here. Highlights so far (for me at least) more stability, lots of copol options via project properties and the start of support for SQL 2005 features/objects, they are not all there yet but its a good sign. Gert and Cameron have more info from the links below on whats new.
Oh and I believe they released a couple of days ahead of schedule. Kudos to Cameron, Gert, Richard and Matt.
