Add version 4.2 to all existing migrations DB schema generated by a migration may look different in rails 4 and 5 (because rails 5 may use different default values). For this reason it's important to explicitly set for which rails version a migration was written for.

length constrain on the index, not on the column we actually don't need a limit on the column itself for MySQL to work. we need to set a length on the index. 2017-07-20 20:07:04 +00:00			`t.binary :primary_keyid`
