===
* Models now parse the results using xmltodict.
* Changed parameter of ``Client.query`` from
``query`` to ``input``.
* ``Client.query`` now accepts keyword arguments
and parameters passed directly to Wolfram|Alpha
as URL parameters.
* ``Result.pods`` and ``Pod.subpods`` now returns
an iterator and not a list.
* ``Pod`` objects are no longer iterable. To access
the subpods of a pod, simply use the ``Pod.subpod``
property.
* ``Result.tree`` and ``Pod.node`` have been removed.
* ``Result`` now additionally presents the new attributes:
- assumptions: An iterable of Assumptions.
- warnings: An iterable of Warnings.
- info: An iterable combining all Pods, Assumptions,
and Warnings.
