Changes 1.5.1:
The biggest fix is for a memory leak introduced in Django 1.5. Under certain \ 
circumstances, repeated iteration over querysets could leak memory - sometimes \ 
quite a bit of it. If you'd like more information, the details are in our ticket \ 
tracker (and in a related issue in Python itself).

If you've noticed memory problems under Django 1.5, upgrading to 1.5.1 should \ 
fix those issues.

Django 1.5.1 also includes a couple smaller fixes:
* Module-level warnings emitted during tests are no longer silently hidden.
* Prevented filtering on password hashes in the user admin.
