upgrade:
  - |
    New config ``max_nova_api_microversion`` to set the maximum nova
    API microversion for nova client plugin. If``max_nova_api_microversion``
    is set, any nova features supported with microversion number above
    max_nova_api_microversion will not be available.
deprecations:
  - |
    ``personality`` property of ``OS::Nova::Server`` is now deprecated, please
    use ``user_data`` or ``metadata`` instead. If that property really
    required, use config ``max_nova_api_microversion`` to set the maximum nova
    API microversion <2.57 for nova client plugin to support personality
    property.
