Hai there. Do anyone knows how to do comparison or is there any document that shows or list all the changes between this version and other version. example for Elasticsearch version 7.3.1, what is the changes or what has been added or removed in Elasticsearch 7.17.1. this is due to I just upgrade straight from 7.3.1 version to not really latest version. so hard to keep track what is the changes along it and want to do the comparison for those two version only instead of list all the changes until latest version i use. thank a lot ---

Elasticsearch version 7.3 is [EOL](https://www.elastic.co/support/eol) and no longer supported. Please upgrade ASAP. (This is an automated response from your friendly Elastic bot. Please report this post if you have any suggestions or concerns :elasticheart: ) ---

7.3.1 Was released in Aug 2019... nearly 2 years ago.. there has been literally 100s of changes included / released up to 7.17.x there is no simple list of changes. There have been major changes in the following... And more Kibana Alerting Lens Visualization Matured ILM Matured APM, / Observability Many Integration Lucene Updates SIEM Maturity Endpoint Integration New data types, Query Improvements Maturing App Enterprise & Workplace Search Maturing ECS Fleet / Elastic Agent Azure , GCP and AWS integrations Etc etc etc (That's just off the top of my head :).) There is a What's New section in the docs for each release. What has not changed, is the underlying index compatibility for the most part. So you should be able to upgrade... of course depending on your use case and implementation there could issues ... Hard to say. ---

Noted on the answer and thanks @stephenb . but is it possible the upgrading version may cause getting different outcome from Elasticsearch? ---

Depends on what you mean by outcome? Can you be more specific? Is it possible? perhaps there has been some upgrades on the lucene versions and I think couple updates on some of the aggregations. If you have specific use cases I would test before and after. ---
