Well, I'm still on Cayenne 3, but the number one thing for me is ObjectCont=
ext.

-- ObjectContext unit of work:  Distinct scratch areas where a set of
changes are proposed, but can be thrown away with no effort, or
committed to the database if kept -- all without ongoing open active
database connections.

-- uniquing of database objects with object context

Most of my work these days is required to be in JPA, and JPA fails to
provide for the above.


Other things I like:

- - custom cgen templates
