--- features: - The ``nova-api``, and ``nova-metadata`` services have moved to run as uWSGI applications. You can override their uwsgi configuration files using the ``nova_api_os_compute_uwsgi_ini_overrides``, and ``nova_api_metadata_uwsgi_ini_overrides`` settings. upgrade: - The ``nova-placement`` service now runs as a uWSGI application that is not fronted by an nginx web-server by default. After upgrading, if the ``nova-placement`` service was running on a host or container without any other services requiring nginx, you should manually remove nginx. deprecations: - Settings related to nginx and the placement will no longer serve any purpose, and should be removed. Those settings are as follows - ``nova_placement_nginx_access_log_format_extras``, ``nova_placement_nginx_access_log_format_combined``, ``nova_placement_nginx_extra_conf``, ``nova_placement_uwsgi_socket_port``, and ``nova_placement_pip_packages``.
