I must admit that the first impression is not so positive: initial reaction was "I have entered the wrong forum!"
At the first glance I had the impression of an out-of-date board: I suppose it is for the overuse of boxes around different sections (message listings, kudos, tags and so on): I have been accustoming to a more "rounded" look and feel.
The "Solution" mark is now less evident and in my opinion it is a loss. On the other hand, it seems easier to reply (and quote) individual messages. Good idea also the "Are you sure" warnign when leaving the message editor without posting.
The interface has been completely localized and this is a sure improvement.
I'm not sure I competely understand the need for "Unread discussions" box in the top right angle: which is the difference between this and the bold highlighting of unread discussions in message listing?
I had the general impression that message list area is smaller than in previous version and globally less easy to read, but it can possibly is a matter of habit...
