There are some significant new features. Here is the definitive list:
https://issues.apache.org/cayenne/secure/IssueNavigator.jspa?
pid=10000&resolution=1&fixfor=10091
And another list here with some highlights:

I have been using 3.0 in production for over 6 months now. It is very
stable and some of its features are things which have been very
important to us.

need to produce cayenne.xml for Cayenne to function.

Absolutely. JPA is an API which forms only a subset of the full
capabilities of Cayenne.

This has been discussed in the last day on the user list. Look for a
message with the subject "Loading multiple cayenne.xml". These
questions about the use of Cayenne are probably more appropriate on
that list.
