Release Version Dates

Elastic Stack Elasticsearch
1

The documentation states

You can upgrade to a higher version if the target version was released after your current version. Upgrades to versions released before your current version are not supported, even if the version number is higher."

https://www.elastic.co/docs/deploy-manage/upgrade#upgrade-paths

Where can I find the dates associated with each version?

dnf --showduplicates list elasticsearch shows that I am currently on version 9.4.5. These versions are listed below that: 9.4.5, 9.5.0, 9.5.1, 9.5.2. How can I determine which of these versions I am able to upgrade to? Is there some way to see the dates associated with each version?

Hello,

You can check on github: Releases · elastic/elasticsearch · GitHub

Also, if you already have patch releases for a minor version, it does not make sense to upgrade to lower patch releases version.

For example, you have 9.5.0, 9.5.1 and 9.5.2, it does not make much sense to upgrade to 9.5.0 or 9.5.2 unless you had to upgrade and there is some know issue on the last patch version.

In this case, there is a know issue in all 9.5.X, you should wait for 9.5.3.

You can see the Know Issues here: Elasticsearch known issues | Elasticsearch Reference

Got it, thanks for your help!

There's also https://ela.st/past-stack-releases if you'd prefer a plain JSON format. Probably you can get that from Github too.

But yes what Leandro said, please steer clear of 9.5.{0,1,2} because of the known issue.
