# Note di rilascio di Django 1.5.1

*28 Marzo 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](https://code.djangoproject.com/ticket/19895) (and in [a related issue](https://bugs.python.org/issue?@action=redirect&bpo=17468) 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
  ([#18985](https://code.djangoproject.com/ticket/18985)).
- Prevented filtering on password hashes in the user admin ([#20078](https://code.djangoproject.com/ticket/20078)).
