Variables

var Migrations = []Migration{}

Add new migrations to the end of this list, and they will be applied before creating the next block. The first migration on the list is applied when schema version = BaseSchemaVersion, and after applying each migration the schema version is incremented. Old migrations can be pruned; for each migration pruned increment BaseSchemaVersion by one.
