# Roadmap to 1.0.0
- Generation of migrations in `db/evolver/migrations` so as not to conflict
with AR migrations.
- Rake task `evolver:migrate`
- Rake task `evolver:revert`
- Rails generator `rails g evolver:migration`.
- Logging of evolutions that have already run in the particular environment,
indicating they can be deleted.
- Multi-database and multi-session evolutions, with evolver keeping track of
what data has been evolved and where.
- Ensuring all migrations always run in safe mode.
- Rake task `evolver:stats` that gives information on run and pending
migrations on each session.
Compatibility
-------------
Evolver is tested against MRI 1.9.3, 2.0.0, and JRuby (1.9).
