+Backwards incompatible changes
+==============================
+
+Restricted filters in admin interface
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The Django administrative interface, django.contrib.admin, supports
+filtering of displayed lists of objects by fields on the corresponding
+models, including across database-level relationships. This is
+implemented by passing lookup arguments in the querystring portion of
+the URL, and options on the ModelAdmin class allow developers to
+specify particular fields or relationships which will generate
+automatic links for filtering.
+
+One historically-undocumented and -unofficially-supported feature has
+been the ability for a user with sufficient knowledge of a model's
+structure and the format of these lookup arguments to invent useful
+new filters on the fly by manipulating the querystring.
+
+However, it has been demonstrated that this can be abused to gain
+access to information outside of an admin user's permissions; for
+example, an attacker with access to the admin and sufficient knowledge
+of model structure and relations could construct query strings which --
+with repeated use of regular-expression lookups supported by the
+Django database API -- expose sensitive information such as users'
+password hashes.
+
+To remedy this, django.contrib.admin will now validate that
+querystring lookup arguments either specify only fields on the model
+being viewed, or cross relations which have been explicitly
+whitelisted by the application developer using the pre-existing
+mechanism mentioned above. This is backwards-incompatible for any
+users relying on the prior ability to insert arbitrary lookups.
