HiveMQ 4.9.16 Maintenance Release

The HiveMQ team is pleased to announce the availability of HiveMQ 4.9.16.

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

HiveMQ Enterprise MQTT Broker

• Reduced the memory footprint of cluster responses to eliminate unnecessary resource use.
• Improved the way cluster nodes exchange metadata to enhance consistency and simplify node information handling.
• Added version compatibility checks to prevent unsupported nodes from joining or merging into a cluster.
• Removed an exception that does not affect cluster functionality to avoid unnecessary clutter in the log statements.

HiveMQ Enterprise Security Extension

• Adjusted support for MSSQL JDBC drivers to compensate for a breaking change that version 10.2.0 of the driver introduces.
• Aligned the permissions cache durations of LDAP authorization managers and MQTT user permissions for improved consistency.

Have a great day, The HiveMQ Team
