In the blog post announcing the release/availability of Open Distro for Elasticsearch 1.8, there’s a link to the “1.8.0 release notes”. Unfortunately, the link takes you to the 1.7.0 release notes…or, rather, it tries to take you to the 1.7.0 release notes…but the page cannot be found and it returns a 404.
Thanks @GSmith. This is resolved and we have added the correct working link. Please check.
