Liquibase

liquibase.org:

1. it understands hibernate definitions.
2. it generates better schema update sql than hibernate
3. it logs which upgrades have been made to a database
4. it handles two-step changes (i.e. delete a column “foo” and then rename a different column to “foo”)
5. it handles the concept of conditional upgrades
6. the developer actually listens to the community (with hibernate if you are not in the “in” crowd or a newbie — you are basically ignored.)
