HiveMQ 4.9.5 Maintenance Release

The HiveMQ team is pleased to announce the availability of HiveMQ 4.9.5.

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

HiveMQ Enterprise MQTT Broker

• Added user feedback during HiveMQ startup to provide detailed information when native SSL is enabled for a deployment.
• Streamlined the client connection context to reduce memory usage per client connection.
• Improved unsubscribe handling to reduce memory consumption per connected client.
• Fixed an issue that generated an exception when a node briefly disconnected from the cluster.
• Fixed an issue that could prevent a reconnecting client from receiving further messages in rare situations.

HiveMQ Enterprise Security Extension

• Mitigated an issue in the HiveMQ Enterprise Security Extension that could negatively impact database operations when the connection to an SQL database is impaired.
• Improved handling in the HiveMQ Enterprise Security Extension to ensure that changes to authorization data in the file-realm configuration file are recognized as expected on Kubernetes.
• Improved user feedback in the HiveMQ Enterprise Security Extension when an MQTT client permission cannot be built.

HiveMQ Enterprise Bridge Extension

• Fixed an issue in the HiveMQ Enterprise Bridge Extension that could cause connection errors for MQTT clients that use TLSv1.2 if native SSL is enabled for the HiveMQ broker.

Have a great day, The HiveMQ Team
