Elastic Stack 8.18.4 released

Version 8.18.4 of the Elastic Stack has been released, offering various performance and stability enhancements over its predecessor, 8.18.3. Notably, Logstash's persistent queue now boasts significantly increased throughput when workers are up to date, achieved by eliminating lock contention in pipeline workers to prioritize queue writers. This improvement is particularly beneficial for pipelines configured with larger batch sizes. Users are encouraged to upgrade to this latest version, and further details on fixed issues and specific changes can be found in the release notes.
