This release includes a number of improvements in order to eliminate unneeded restarts and reduce service downtime:

• Pods are no longer restarted when new shards/replicas are added
• Cluster configuration (remote_servers.xml) is now updated after shards and replicas are added. That reduces a chance to get an error querying distributed tables.
• LoadBalancer node ports are no longer modified on service upgrade. That reduces possible downtime
• Service is re-created if it can not be updated for some reason (e.g. change from ClusterIP to LoadBalancer or vice versa)
• Fixed several race conditions when creating/updating a cluster
