Elasticsearch 6.2.0, based on Lucene 7.2.1, has been released, bringing several noteworthy enhancements and features. This update introduces SAML support for single sign-on with Kibana, allowing for streamlined user management and improved security. Audit filtering has been improved, providing more precise logging options to meet strict compliance standards. The release also debuts a new Ranking Evaluation API to assess and ensure the quality of search results. Additionally, Elasticsearch 6.2.0 includes improved query safeguards, support for Well Known Text in geospatial data, enhanced Task Management API capabilities, and Java 9 support. Despite these advancements, users are cautioned about a bug affecting plugin upgrades and are advised to stick with Java 8 due to the short lifecycle of JDK 9 and 10. The release is available on Elastic Cloud, underscoring Elasticsearch's commitment to evolving its service platform.
