What are the main differences between EJB 2.0 and EJB 3.0?

If you know EJB 2.0 is there a steep learning curve to learn how to use EJB 3.0?

Also does anyone happen to know or know how I can find out which app servers and IDEs are compatible with EJB 3.0?

This kind of question is pretty broad so I'd recommend consulting a textbook or wikipedia for detailed answers, but if my memory serves me correctly the major different between the two is an overhaul of the entity bean system.
