15.1.15 ^^^^^^^
New Features
* The galera cluster now supports cluster health checks over HTTP using port 9200. The new cluster check ensures a node is healthy by running a simple query against the wsrep sync status using monitoring user. This change will provide for a more robust cluster check ensuring we have the most fault tolerant galera cluster possible.
* Galera healthcheck has been improved, and relies on an xinetd service. By default, the service is unaccessible (filtered with the no_access directive). You can override the directive by setting any xinetd valid value to "galera_monitoring_allowed_source".
