Wagtail now supports Elasticsearch 2. Note that you need to change backend in ``WAGTAILSEARCH_BACKENDS``, if you wish to switch to Elasticsearch 2. This feature was developed by Karl Hobley.
* The ``wagtailforms`` module now provides a ``FormSubmissionPanel`` for displaying details of form submissions; see :ref:`wagtailforms_formsubmissionpanel` for documentation. (João Luiz Lorencetti)
* The Wagtail version number can now be obtained as a tuple using ``from wagtail import VERSION`` (Tim Heap)
*``send_mail`` logic has been moved from ``AbstractEmailForm.process_form_submission`` into ``AbstractEmailForm.send_mail``. Now it's easier to override this logic (Tim Leguijt)
* Image rendition / document file deletion now happens on a post_delete signal, so that files are not lost if the deletion does not proceed (Janneke Janssen)
