========================== 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). __ https://code.djangoproject.com/ticket/19895 __ https://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 (:ticket:`18985`). * Prevented filtering on password hashes in the user admin (:ticket:`20078`).
