DefNet 6.0.0
BREAKING CHANGE: The p2p_discovery module will no longer stop the discovery service when it finds a host. It is up to the listener to decide if discovery should end or continue in search of additional hosts.
NEW: The p2p_discovery module will now send any additional discovery data that is encountered after the discovery message to the listener. This allows a client to pass extra data such as a user id or other token or information to the host.
