+HTML5
+~~~~~
+
+We've switched the admin and other bundled templates to use the HTML5
+doctype. While Django will be careful in its use of HTML5 features, to maintain
+compatibility with old browsers, this change means that you can use any HTML5
+features you need in admin pages without having to lose HTML validity or
+override the provided templates to change the doctype.
