HiveMQ Community Edition 2023.1 is released

The HiveMQ team is pleased to announce the availability of HiveMQ CE 2023.1.

This release provides plenty of great improvements and fixes:

🌟 Features

• Added XSD schema files for validation of broker configuration files
• Added native M1 RocksDB library to HiveMQ bundles for better manageability when running HiveMQ with RocksDB on MacBook M1 models.

✨ Improvements

• Improved the priority handling of HiveMQ extensions that use the same extension services to avoid possible conflicts.
• Adjusted the naming of extension executors to facilitate accurate debugging.
• Optimized memory consumption when millions of clients are connected.
• Improved performance for use cases that have a large number of subscribers for the same shared subscription group.
• Improved stability and performance for inbound PUBLISH packets to high volume shared subscriptions
• Optimized caching to eliminate unnecessary Java heap memory consumption.
• Improved HiveMQ event log feedback for failed authentication to include custom reason strings from extensions.
• Increased message throughput rates and payload cleanup performance in deployments with a large number of CPU cores.

🐞 Bug fixes

• Fixed an issue that could prevent successful HiveMQ shutdown when the diagnostic mode is enabled.
• Fixed an issue that could cause the HiveMQ broker to log duplicate extension starts during startup on some Windows desktop installations.
• Fixed an issue that could cause incorrect handling of will messages when a client reconnects or takes over a session with an enabled clean start flag.
• Fixed an issue to prevent a potential memory leak on systems where no extension sets plugin initializers.
• Improved handling in the cleanup service to fix an issue that could cause a periodic cleanup task to get stuck.

ℹ️ Misc
