  7. This is Django 1.5.1, a bugfix release for Django 1.5. It's completely backwards
    
  8. compatible with Django 1.5, but includes a handful of fixes.
    
  9. 
    
  10. The biggest fix is for a memory leak introduced in Django 1.5. Under certain
    
  11. circumstances, repeated iteration over querysets could leak memory - sometimes
    
  12. quite a bit of it. If you'd like more information, the details are in
    
  13. :ticket:`our ticket tracker <19895>` (and in :bpo:`a related issue <17468>` in
    
  14. Python itself).
    
  15. 
    
  16. If you've noticed memory problems under Django 1.5, upgrading to 1.5.1 should
    
  17. fix those issues.
    
  18. 
    
  19. Django 1.5.1 also includes a couple smaller fixes:
    
  20. 
    
  21. * Module-level warnings emitted during tests are no longer silently hidden
    
  22.   (:ticket:`18985`).
    
  23. * Prevented filtering on password hashes in the user admin (:ticket:`20078`).
