I see Scrivener 1.5.3.0 was released yesterday: http://www.literatureandlatte.com/scrivWinChangeList.php

Some of the more interesting enhancements:

OPML Import
OPML export
Mind map import (Freemind .mm format)
Mind map export (Freemind .mm format)
CSV export
Import and Split functionality
Comprehensive Print preview functionality
Print index cards
Print outliner

They also say "Scrivener is much faster and more robust." Well, let's see about that. That's been my main bugbear.
