  • Documented the completed plugin policy hook loop for OnMessagePublish and OnMessageSubscribe.
  • Clarified that publish policy hooks can reject or rewrite messages before retain storage, QoS persistence, and routing.
  • Clarified that subscribe policy hooks can reject topic filters or downgrade the granted QoS before subscription storage and retained delivery.
  • Added observability documentation for node-local $SYS topics and the protected /metrics endpoint.
  • Updated the feature list and roadmap to distinguish node-local observability from future global cluster metrics aggregation.

  • Aligned the website with the secure-by-default first-run behavior in the main YedMQ repository.
  • Updated get-started, security, mqtt-configuration, plugin-configuration, and listener-configuration to reflect localhost-only API binding, an empty default API user list, and deny-by-default MQTT fallback behavior.
  • Added guidance for local smoke tests and the bundled acl_file example plugin.
