Version 8.4.3 of the Elastic Stack was released on October 5, 2022, addressing a significant bug introduced in the previous 8.4.2 release that affected Elasticsearch's cross_fields type, potentially causing query failures. Users relying on this feature are encouraged to upgrade to the latest version to prevent encountering errors related to term frequency discrepancies. The update is preferred over earlier patch versions in the 8.4.x series, and detailed information about fixed issues and changes across various products within the Elastic Stack, including Elasticsearch, Kibana, Beats, Logstash, and others, can be found in the 8.4.3 release notes.
