* Added that the MySQL adapter should map integer to either smallint, int, or bigint depending on the :limit just like PostgreSQL [DHH]
|

|
||||
* Change validates_uniqueness_of :case_sensitive option default back to true (from [9160]). Love your database columns, don't LOWER them. [rick]
|
||||
|
||||
* Add support for interleaving migrations by storing which migrations have run in the new schema_migrations table. Closes #11493 [jordi]
