--- upgrade: - | Deprecated option ``[keystone]\region_name`` was removed and will be ignored. Instead use ``region_name`` option in other sections related to contacting other services (``[service_catalog]``, ``[cinder]``, ``[glance]``, ``[neutron]``, [``swift``] and ``[inspector]``). As the option ``[keystone]\region_name`` was the only option in ``[keystone]`` section of ironic configuration file, this section was removed as well.
