Elastic Stack Release - 5.0.0-rc1

By Tyler Hannan

We’ve reached a milestone in the 5.0.0 release. 

Today, we are pleased to announce that the first 5.0 release candidate is available for download. At Elastic, a release candidate indicates that the products should look, and feel, very similar to the final GA release. We do use this period to squash any final bugs that may arise.

In addition, this is the first time we're releasing an early access version in Elastic Cloud, which makes it even easier to test such releases now. To start with, we're rolling it out to Ireland (eu-west-1) and Virginia (us-east-1) AWS regions. This is the first step in making all early access releases, including betas, alphas and even nightly builds, available on cloud so that our users can easily test them out and provide feedback on the latest and greatest

Before you get too excited, keep in mind that this is still a release candidate, so don’t put it into production. If you open a bug report, today, you too can become an Elastic Pioneer. And now, without further ado, some highlights from rc1.


For more detailed information, and many other features, peruse the Elasticsearch detail post.

  • Strict URL query-string parameter parsing - have you spent time wondering why the tokenzier wasn’t working? Only to find out that you meant tokenizer? No longer.

From 2.4.x to 5.0. The magical journey. The undiscovered country. The next frontier. Other coined phrases. As a reminder, we’ve also released the Migration Helper, which runs on your existing 2.4 cluster.  Use this site plugin to prep for your migration.


The theme here is squashing bugs. Shimmy your way over to the Kibana detail post to see everything that’s changed. In the meantime, some highlights:

  • Mappings can now be fetched when using an index alias
  • Long legends no longer expand the height of the entire page
  • Charts no longer render twice, which was degrading performance


Thanks to all your feedback on our prereleases! We’ve squashed a few bugs and improved log messages when Logstash is started as a *nix service. Details in the release notes.


Lightweight data shippers. Not so lightweight changes. Explore them all in the detail post.

  • Future upgrades are easier - We’ve updated the mapping templates to automatically set unknown strings and to serialize float values with decimals.
  • Custom BPF filters for Packetbeat are back!

Get it Now!

Happy testing. Your feedback is instrumental in making 5.0 successful. And, don't forget that X-Pack is here and continually being updated with each pre-release.
