• It still crashes- even with service pack 2
• No improvements to the timeline, or keyframe editing
• No feedback on rendering, the progress box locks up, and no time estimate.
• Rendering is still v–e–r–y s..l..o..w
• There are fewer body morphs for ther new figures ( though those present are easier to use)

But, on the other hand:

• The interface is slightly better
• hair simulations are quicker
• the new figures are really rather good, and not too much of a resource hog.
