        .. versionchanged:: 2.1
            Removed the ``as_tuple`` parameter.

        .. versionchanged:: 2.0
            The request input stream is closed when calling
            ``response.close()``. Input streams for redirects are
            automatically closed.

        .. versionchanged:: 0.5
            If a dict is provided as file in the dict for the ``data``
            parameter the content type has to be called ``content_type``
            instead of ``mimetype``. This change was made for
            consistency with :class:`werkzeug.FileWrapper`.

        .. versionchanged:: 0.5
            Added the ``follow_redirects`` parameter.
