- Update to 1.0.0
* Added support for Python 3.8 and 3.9.
* ``StatefulBrowser`` has new properties ``page``, ``form``, and ``url``,
which can be used in place of the methods ``get_current_page``,
``get_current_form`` and ``get_url`` respectively
* ``StatefulBrowser.form`` will raise an ``AttributeError`` instead of
returning ``None`` if no form has been selected yet.
* Decompose ```` elements with the same name when adding a new
input element to a form.
* The ``params`` and ``data`` kwargs passed to ``submit`` will now properly
be forwarded to the underlying request for GET methods (whereas previously
``params`` was being overwritten by ``data``).
