by HiveMQ TeamFEB 8, 2023

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

  • Updated dependencies on third-party libraries.
