Is there any way to list down the differences (compare) between two different versions of elastic stack?

Hi,

I would like to know if there is any way to do this, what I am trying to achieve is pretty straightforward (not too simple I guess). Suppose, I am planning to upgrade from Kibana 6.3.0 to Kibana 7.7.0, or Elasticsearch 6.6.2 to 7.7.0, I want to list down the change set (breakthrough changes at least).

Why this becomes relevant is in situations while we create a report of upgrade plan, or similar. Is there any existing solution for this? If no, is there any way around or any possibility to achieve this?

Thank you.

Well you still can do some git diff on kibana repo but IMHO you should give a look to https://www.elastic.co/blog/category/releases .
