The HiveMQ team is pleased to announce the availability of HiveMQ 4.9.13.

This maintenance release for the 4.9 series includes the following improvements:

HiveMQ Enterprise MQTT Broker

  • Fixed an issue that could prevent correct monitoring when a file system is created directly on an unpartitioned disk.
  • Fixed an issue that could cause logging statements for some failure detection events to contain insufficient information.
  • Fixed an issue to ensure that a CONNACK message is sent if a connection closes due to a CONNECT package that exceeds the configured maximum message size.

HiveMQ Enterprise Distributed Tracing Extension

  • Updated span attribute names to support new OpenTelemetry semantic conventions.

HiveMQ Enterprise Extension for Kafka

  • Fixed an issue that could cause a QoS 0 PUBLISH message to be unnecessarily resent to Kafka after the initial delivery attempt fails.

HiveMQ Enterprise Extensions

  • Improved XSD rules to ensure that route IDs in the extension configuration do not include invalid characters. The new validation is implemented for the following enterprise extensions:
    • HiveMQ Enterprise Bridge Extension
    • HiveMQ Enterprise Extension for kafka


  • Added SIGPIPE signal handling to the MQTT subscribe command to facilitate integration with other processes.
  • Fixed an issue that prevented the display of multiple user properties with the same name.
