@ -99,6 +99,23 @@ allows you to fix a very common performance problem in which your code ends up
doing O(n) database queries (or worse) if objects on your primary ``QuerySet``
each have many related objects that you also need.
Improved password hashing
~~~~~~~~~~~~~~~~~~~~~~~~~
Django's auth system (``django.contrib.auth``) stores passwords using a one-way
algorithm. Django 1.3 uses the SHA1_ algorithm, but increasing processor speeds
and theoretical attacks have revealed that SHA1 isn't as secure as we'd like.
Thus, Django 1.4 introduces a new password storage system: by default Django now
uses the PBKDF2_ algorithm (as recommended by NIST_). You can also easily choose
a different algorithm (including the popular bcrypt_ algorithm). For more
details, see :ref:`auth_password_storage`.
