# Django 1.7.4 リリースノート

January 27, 2015

Django 1.7.4 fixes several bugs in 1.7.3.

## バグ修正

- Fixed a migration crash when unapplying `contrib.contenttypes`’s or `contrib.auth`’s first migration (#24075).

- Made the migration's `RenameModel` operation rename `ManyToManyField` tables (#24135).

- Fixed a migration crash on MySQL when migrating from a `OneToOneField` to a `ForeignKey` (#24163).

- Prevented the `static.serve` view from producing `ResourceWarning`s in certain circumstances (security fix regression, #24193).

- Fixed schema check for ManyToManyField to look for internal type instead of checking class instance, so you can write custom m2m-like fields with the same behavior. (#24104).
