The only thing I've changed is that I've gotten rid of the borders. The banner at the top that has links to community, blog and the lussumo logo aren't in the release version - they're actually an extension I made for the community site.
It's almost exactly the same as the last version style-wise - a little simpler css-wise, actually.
timberford: mini is right - I changed up the cookies, so you may have to wipe your lussumo cookies and start fresh in order for it to work properly.
Also, yes, I bet you can use the 092 style on this forum and it should work for the most part. I haven't tried it myself - you *may* need to make some changes to some screens to make it look correct.
