Django 1.7.4 fixes several bugs in 1.7.3.
Fixed a migration crash when unapplying
contrib.auth’s first migration (#24075).
Made the migration’s
RenameModel operation rename
Fixed a migration crash on MySQL when migrating from a
OneToOneField to a
static.serve view from producing
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).
