Django 1.5.5 release notes
October 23, 2013
Django 1.5.5 fixes a couple security-related bugs and several other bugs in the
Readdressed denial-of-service via password hashers
Django 1.5.4 imposes a 4096-byte limit on passwords in order to mitigate a
denial-of-service attack through submission of bogus but extremely large
passwords. In Django 1.5.5, we’ve reverted this change and instead improved
the speed of our PBKDF2 algorithm by not rehashing the key on every iteration.
Properly rotate CSRF token on login
This behavior introduced as a security hardening measure in Django 1.5.2 did
not work properly and is now fixed.
- Fixed a data corruption bug with datetime_safe.datetime.combine (#21256).
- Fixed a Python 3 incompatibility in django.utils.text.unescape_entities()
- Fixed a couple data corruption issues with QuerySet edge cases under
Oracle and MySQL (#21203, #21126).
- Fixed crashes when using combinations of annotate(),
select_related(), and only() (#16436).
Backwards incompatible changes
- The undocumented django.core.servers.basehttp.WSGIServerException has
been removed. Use socket.error provided by the standard library instead.
