We have a page that lists recent published viewers at https://releasenotes.secondlife.com/categories/viewer.html which is handy for reading old Release notes or debugging when a bug came into existence.

A link to that page should be added to the sidenav of https://releasenotes.secondlife.com/

Alternately, add a link to this page from https://releasenotes.secondlife.com/index.html which already has a link to (very) old viewers.
