HiveMQ 4.28.5 Maintenance Release

The HiveMQ team is pleased to announce the availability of HiveMQ 4.28.5.

This maintenance release for the 4.28 series includes the following improvements:

HiveMQ Enterprise MQTT Broker

• Fixed an issue that could cause the broker to send PUBLISH packets with QoS 0 in an incorrect order.
• Improved client workload performance during background tombstone cleanup and topology change replication operations.
• Sped up join process operations on the joining node to improve performance.

HiveMQ Enterprise Security Extension

• Fixed an issue that could prevent LDAP authentication when multiple LDAP authentication managers are configured for the same LDAP realm.

HiveMQ Enterprise Extension for MongoDB

• Fixed metrics cleanup on extension stop, which would prevent subsequent extension starts.
• Improved log statements to reduce ambiguity on batch operations that span multiple topics.

Have a great day, The HiveMQ Team
