The HiveMQ team is pleased to announce the availability of HiveMQ 3.1.9. This is a maintenance release and brings the following improvements:

• Added metrics for dropped messages by reason for dropping
• Fixed an issue that could cause increased traffic while replicating in the cluster
• Fixed an issue that could cause duplicate messages during a rolling upgrade in rare cases
• Fixed an issue with nodes joining an existing cluster in rare cases
• Improved logging

You can download the new HiveMQ version here.

We recommend to upgrade if you are an HiveMQ 3.1.x user.

Have a great day, The HiveMQ Team
