16.0.0.0rc1-10

Upgrade Notes

• Tacker no longer depends on eventlet. The library has been removed from the requirements, and none of the services monkey patches the standard library anymore. The API runs as a WSGI application under a WSGI server such as uWSGI, and oslo.service uses its threading backend.

• The eventlet based standalone API server tacker-server has been removed as part of the eventlet removal. Run the Tacker API with a WSGI server such as uWSGI or mod_wsgi using the tacker.api.wsgi.api:application WSGI application instead, as the devstack plugin does. The configuration options bind_host, bind_port, api_workers and the socket options of the removed server (backlog, tcp_keepidle, retry_until_window, max_header_line, use_ssl, ssl_ca_file, ssl_cert_file and ssl_key_file) have also been removed. The listen address and the number of workers are now configured on the WSGI server side.
