0.11
----
- Backwards-incompatible API changes
- Improve documentation
- Detect circular dependencies between evolution modules
- Regain 100% statement coverage (however, unit tests depend on several
  unreleased packages)

0.10
----
- Add multi-package schema evolution support with DAG-ordered dependencies

0.9
---

- Rename to stucco_evolution
- stucco_evolution's own upgrade() will now deletage all
  stucco_evolution.Base.metadata.crete_all(session) to the evolveN.py
  scripts. This avoids 'DROP TABLE' statements when an upgrade includes
  table renames.

0.8998
------

- Improved packageability (MANIFEST.in specified)
- SQLAlchemyEvolutionManager no longer calls session.commit(); this is
  your responsibility after the migration has completed.
