  * On the off chance you have legacy URLconfs that have NO captured items but DO use capturing parenthesis (which until now would have had no effect), you'll need to either change your view code to accept the captured values, or uncapture them.
+
+== Changed behavior of MultiValueDict.items() ==
+
+In [1504], the {{{MultiValueDict}}} (and {{{QueryDict}}}) {{{items()}}} method was changed to return the *last* member of each list rather than the full list.
+
+This probably doesn't affect anybody, but it's listed here for completeness.
+
+Old behavior:
+{{{
+>>> q = QueryDict('a=1&a=2')
+>>> q.items()
+[('a', ['1', 2'])]
+}}}
+
+New behavior:
+{{{
+>>> q = QueryDict('a=1&a=2')
+>>> q.items()
+[('a', '2')]
+}}}
+
+To emulate the old behavior, use the new {{{lists()}}} method:
+
+{{{
+>>> q = QueryDict('a=1&a=2')
+>>> q.lists()
+[('a', ['1', 2'])]
+}}}
