3.254.0

Added

• Added NATS queue type to the split_queues config.

Fixed

• Failed iptables rule removal during steal port teardown no longer disconnects
  all clients.
• Fixed mirrord db-branches connections showing no port forward for branches
  whose connection parameters use value_pattern sources.
• Keep remote file operations and cleanup working after an agent reconnect.
• Make mirrord user data updates atomic so concurrent processes and interrupted
  writes do not corrupt or lose stored
  data.
