*******************
Features:
- *Backwards-incompatible*: Support multiple APIs in a single application via
``Api`` param ``config_prefix``. The ``Api`` object is now accessible at
``app.extensions["flask-smorest"]["apis"][config_prefix]["ext_obj"]``
rather than ``app.extensions["flask-smorest"]["ext_obj"]``. (:pr:`485`)
Thanks :user:`petraszd` for the contribution.
Other changes:
- Drop support for Python 3.7 (:pr:`497`).
- Require Werkzeug>=2.0.1 (:pr:`485`).
