Elastic Stack 6.0.0-rc2 released

Editor's Note (August 3, 2021): This post uses deprecated features. Please reference the map custom regions with reverse geocoding documentation for current instructions.

If youve been following along closely you will be aware that weve been busy in preparation for 6.0.0 GA. It is our intent, and hope, that rc2 represents as close to final code as is possible before the GA release. This also means that -- if you want to test in advance of GA -- this could be close to your final chance.

While releasing all the things on the same day is no trick (but quite the feat of coordination), we do hope you find it a treat to play with upcoming features. We continue to work hard squashing bugs and adding features to each product because, like mummies, we are afraid to unwind.

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

Keep in mind that you can try it on Elastic Cloud. Thats correct, release candidates are now available on your favourite hosted Elasticsearch provider.

All of the products have multiple changes of varying complexity. We'd encourage you to test with the entire Elastic Stack.
