    505505 * 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.

     507== Changed behavior of MultiValueDict.items() ==
     508
     509In [1504], the {{{MultiValueDict}}} (and {{{QueryDict}}}) {{{items()}}} method was changed to return the *last* member of each list rather than the full list.
     510
     511This probably doesn't affect anybody, but it's listed here for completeness.
     512
     513Old behavior:
     514{{{
     515>>> q = QueryDict('a=1&a=2')
     516>>> q.items()
     517[('a', ['1', 2'])]
     518}}}
     519
     520New behavior:
     521{{{
     522>>> q = QueryDict('a=1&a=2')
     523>>> q.items()
     524[('a', '2')]
     525}}}
     526
     527To emulate the old behavior, use the new {{{lists()}}} method:
     528
     529{{{
     530>>> q = QueryDict('a=1&a=2')
     531>>> q.lists()
     532[('a', ['1', 2'])]
     533}}}
