Elastic Stack 6.0.0-rc1 released

Editor's Note (September 7, 2018): This post refers to X-Pack. Starting with the 6.3 release, the X-Pack code is now open and fully integrated as features into the Elastic Stack.

6.0.0-rc1 is available today! And, because multiple releases on the same day are amazing, we also GAed Google Cloud as a hosting option for Elastic Cloud.

Not only are we approaching, rapidly, the GA of 6.0.0, we are super excited that this release includes the alpha release of Elastic APM. Although it is in alpha, it has been running on multiple sites for some time and it wouldnt be a proper dogfooded release if we didnt sip the champagne while mixing our metaphors. If you want more history on why Elastic APM, Welcome Opbeat to the Elastic Family is a great place to start .

During the 5.0 release, we introduced the Elastic Pioneer Program and are continuing the same program with the 6.0 preview releases.

Before you get too excited, keep in mind that this is still a release candidate so dont put it into production. There is no guarantee that any of the 6.0.0 pre-release versions will be compatible with other pre-releases, or the 6.0.0 GA. We strongly recommend that you keep this far, far away from production.

But we also recommend that you try it on Elastic Cloud. Thats correct, now that we have a release candidate it is available on your favourite hosted Elasticsearch provider. (Or will be by the time you read this).
