Django 1.7.5 release notes

February 25, 2015

Django 1.7.5 fixes several bugs in 1.7.4.

Bugfixes

• Reverted a fix that prevented a migration crash when unapplying contrib.contenttypes’s or contrib.auth’s first migration (:ticket:`24075`) due to severe impact on the test performance (:ticket:`24251`) and problems in multi-database setups (:ticket:`24298`).
• Fixed a regression that prevented custom fields inheriting from ManyToManyField from being recognized in migrations (:ticket:`24236`).
• Fixed crash in contrib.sites migrations when a default database isn’t used (:ticket:`24332`).
• Added the ability to set the isolation level on PostgreSQL with psycopg2 ≥ 2.4.2 (:ticket:`24318`). It was advertised as a new feature in Django 1.6 but it didn’t work in practice.
• Formats for the Azerbaijani locale (az) have been added.
