upgrade:
  - |
    Support for running WSGI services under Apache+mod_wsgi has been dropped.
    All API services now run exclusively under uWSGI. The ``*_wsgi_provider``
    variables (``keystone_wsgi_provider``, ``nova_wsgi_provider``,
    ``cinder_wsgi_provider``, etc.) have been removed. If you had any of these
    set to ``apache`` in your configuration, remove them before upgrading.
