titleMQTT Distributor


Expand
titleWhat's New or Improved
  • Bounded the MQTT Clients dataset and coalesced its updates so a busy server no longer grows the table without limit
  • Added a software bill of materials (SBOM) to the module build output
    • No new features


Expand
titleWhat's Fixed
  • Fixed connection issues with clients with no specified client ID
  • Fixed possible minor delay in processing QoS 2 messages
  • Fixed packet identifier warnings in log
  • the MQTT server continuing to run under the previous configuration after settings were saved; it is now stopped before the new configuration is applied

  • MQTT Client info tag creation is now retried until it succeeds, and tag claims are keyed to the client rather than the server name
  • Edge Node ID List entries in a Topic Token Filter are now trimmed, and an unusable list warns once per list instead of once per rebuild
  • UDT definitions are now published for UDT instances at the root of a Tag Provider

    • The in-order history flush now reports its outcome with both delivered and residual record counts
    • The embedded H2 history database is now confined to loopback with secured accounts, and its credentials are stored so that a gateway backup carries them
