  • Fixed an issue that could cause a retained message to be sent without publish attributes.
  • Improved HiveMQ startup to provide greater speed and stronger data folder protection.
  • Improved the way that disconnects due to keep-alive timeouts are handled to provide greater resilience in case of a massive disconnect wave.
  • Reduced memory usage during backup creation for better handling of sizable message queues with large messages.
  • Enhanced INFO level log statements to provide detailed reason information when a backup restoration contains invalid data.
  • Adjusted HiveMQ platform bundling to ensure that only the latest version of the MQTT CLI tool is included in the package.
  • Fixed an issue in the MQTT CLI issue that caused errors when displaying incoming publishes with correlation data as JSON.
  • Added validation in HiveMQ Swarm to ensure that messageExpiry and keepAlive are within bounds.
  • Added proper feedback for agents in HiveMQ Swarm when allocating the listening port fails.
  • Fixed an issue in HiveMQ Swarm to ensure that all clients disconnect when a scenario is interrupted.
  • Fixed an issue in HiveMQ Swarm to ensure that will-messages are correctly sent in every case.
