  9. Bugfixes
    
  10. ========
    
  11. 
    
  12. * Reverted a fix that prevented a migration crash when unapplying
    
  13.   ``contrib.contenttypes``’s or ``contrib.auth``’s first migration
    
  14.   (:ticket:`24075`) due to severe impact on the test performance
    
  15.   (:ticket:`24251`) and problems in multi-database setups (:ticket:`24298`).
    
  16. 
    
  17. * Fixed a regression that prevented custom fields inheriting from
    
  18.   ``ManyToManyField`` from being recognized in migrations (:ticket:`24236`).
    
  19. 
    
  20. * Fixed crash in ``contrib.sites`` migrations when a default database isn't
    
  21.   used (:ticket:`24332`).
    
  22. 
    
  23. * Added the ability to set the isolation level on PostgreSQL with psycopg2 ≥
    
  24.   2.4.2 (:ticket:`24318`). It was advertised as a new feature in Django 1.6
    
  25.   but it didn't work in practice.
    
  26. 
    
  27. * Formats for the Azerbaijani locale (``az``) have been added.
