// NOTE: Until the first public release, i may collapse multiple
// migrations into a single one. this will require db recreation
// NOTE: I might fuck with these until the v0.1 release. After that, I'll guarantee that you
// can upgrade to any v0.x release by just running unapplied migrations in order. You might
// need extra work to upgrade to v1.0 but you shouldn't have to recreate the db.
