Product release

Elasticsearch 6.0.0-beta2 released

Editors note: this post originally had an incorrect statement around the new X-Pack keystore workings.  While the discrepancy wouldn't have an effect on the benefit of the release, we wanted to update this blog to give a more accurate reflection of what's going on behind the scenes.

We are excited to announce the release of Elasticsearch 6.0.0-beta2, based on Lucene 7-SNAPSHOT. This is the fourth in a series of pre-6.0.0 releases designed to let you test out your application with the features and changes coming in 6.0.0, and to give us feedback about any problems that you encounter. Open a bug report today and become an Elastic Pioneer.

IMPORTANT: This is a beta release and is intended for testing purposes only. Indices created in this version will not be compatible with Elasticsearch 6.0.0 GA. Upgrading 6.0.0-beta2 to any other version is not supported.

You can read about all the changes in the release notes linked above, but there is one big change worth mentioning below.

Better Security bootstrap experience

In 6.0.0-beta1 we announced that default passwords have been removed  in X-Pack Security and that a bootstrap.password setting should be added to the secure keystore before startup. We have now improved this experience by auto-generating a random seed so as a user you don't need to interact with the keystore unless there are other secrets you wish to store. This all happens automatically for you when X-Pack is installed.

You can still use the setup-passwords command line tool to generate and set strong passwords for all of the internal users.  If you're interested in giving X-Pack a shot, hop on over to the X-Pack installation page for a quick getting started guide.


Please download Elasticsearch 6.0.0-beta2, try it out, and let us know what you think on Twitter (@elastic) or in our forum. You can report any problems on the GitHub issues page.
