Django 1.5.1 release notes

==========================

*March 28, 2013*

This is Django 1.5.1, a bugfix release for Django 1.5. It's completely backwards

compatible with Django 1.5, but includes a handful of fixes.

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).

__ http://bugs.python.org/issue17468

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

  (`#18985`__).

* Prevented filtering on password hashes in the user admin (`#20078`__).
