HiveMQ 4.28.27 Maintenance Release

The HiveMQ team is pleased to announce the availability of HiveMQ 4.28.27.

This maintenance release for the 4.28 series includes the following bug fixes and improvements:

HiveMQ Enterprise MQTT Broker

• Increased the receive buffer size for HiveMQ bridge client connections.
• Fixed a rare merge replication condition that could cause dropped messages.
• Added TCP memory metrics (com.hivemq.system.os.network.tcp.memory.pages.used and com.hivemq.system.os.network.tcp.memory.pages.max) to monitor current TCP memory usage and the configured system limit on Linux deployments.
• Improved diagnostic archive security by automatically redacting the values of environment variables and JVM system properties whose key names contain sensitive terms.

HiveMQ Enterprise Bridge Extension

• Added a configuration option to enable TLS hostname verification.

HiveMQ Enterprise Security Extension

• Fixed incorrect target tables for several indexes and triggers in the packaged SQL create scripts for PostgreSQL and MySQL.

HiveMQ Enterprise Extension SDK

• Added runtime deprecation warnings that flag the Enterprise Extension SDK methods and bridge configurations scheduled to change in the next HiveMQ LTS release.

Have a great day, The HiveMQ Team
