--- features: - The ``openstack-ansible-galera_server`` role will now prevent deployers from changing the ``galera_cluster_name`` variable on clusters that already have a value set in a running galera cluster. You can set the new ``galera_force_change_cluster_name`` variable to ``True`` to force the ``galera_cluster_name`` variable to be changed. We recommend setting this by running the galera-install.yml playbook with ``-e galera_force_change_cluster_name=True``, to avoid changing the ``galera_cluster_name`` variable unintentionally. Use with caution, changing the ``galera_cluster_name`` value can cause your cluster to fail, as the nodes won't join if restarted sequentially.
