Hey Robert,
I did a quick search internally and I didn't see anything related to version numbers for the Release Notes. It looks like the last version reported was in September of 2018.
If you would like to see the version numbers on the Release Notes page going forward, I would recommend scrolling to the Was this article helpful? feature at the bottom of the pages. If you select No, you are able to leave feedback that will be sent to the team that manages those articles.
