Elasticsearch 6.0.0-beta2, based on Lucene 7-SNAPSHOT, has been released as the fourth pre-6.0.0 version, aimed at allowing users to test features and provide feedback before the official release. This beta version is intended solely for testing purposes and should not be used in production, as indices created with it will not be compatible with the forthcoming 6.0.0 GA version, and upgrading from 6.0.0-beta2 to any other version is not supported. A notable improvement in this release is the enhanced security bootstrap experience, where default passwords have been removed in X-Pack Security, and a random seed is now auto-generated for the keystore, reducing user interaction unless other secrets are to be stored. Users are encouraged to try this beta version and share their feedback via Twitter, forums, or the GitHub issues page.
