* The admin CSS class ``field-box`` is renamed to ``fieldBox`` to prevent
conflicts with the class given to model fields named "box".
+* Since the admin's ``actions.html``, ``change_list_results.html``,
+ ``date_hierarchy.html``, ``pagination.html``, ``prepopulated_fields_js.html``,
+ ``search_form.html``, and ``submit_line.html`` templates can now be
+ overridden per app or per model, you may need to rename existing templates
+ with those names that were written for a different purpose.
+
* ``QuerySet.raw()`` now caches its results like regular querysets. Use
``iterator()`` if you don't want caching.
