******************
* *Backwards-incompatible*: Rename ``URL`` and ``AbsoluteURL`` to ``URLFor`` and ``AbsoluteURLFor``, respectively, to prevent overriding marshmallow's ``URL`` field (:issue:`6`). Thanks :user:`svenstaro` for the suggestion.
* Fix bug that raised an error when deserializing ``Hyperlinks`` and ``URL`` fields (:issue:`9`). Thanks :user:`raj-kesavan` for reporting.
Deprecation:
* ``Schema.jsonify`` is deprecated. Use ``flask.jsonify`` on the result of ``Schema.dump`` instead.
* The ``MARSHMALLOW_DATEFORMAT`` and ``MARSHMALLOW_STRICT`` config values are deprecated. Use a base ``Schema`` class instead (:issue:`8`).
