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 :ticket:`our ticket tracker <19895>` (and in :bpo:`a related issue <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 (:ticket:`18985`).
- Prevented filtering on password hashes in the user admin (:ticket:`20078`).
