I've attached a link to Eovia's "What's New" page for C3. As far as I can tell, everyone that's upgraded finds the product more stable, easier to use, faster, and - oh, yeah - there are several new features. There has been some whining that the animation tools and bones haven't been improved, but that's all. IMHO, it's definitely worth the upgrade. - Jasen.
