> which was the last major version that supported upgrading in place from the previous versions
This isn't correct. Yes it was true from Drupal 7 to 8, but one of the primary goals of that change was so that every major version after could have seamless in-place upgrades - which they have. Yes there's deprecated code etc. that you might run into in contrib. or custom modules, but the site upgrades themselves are easier than ever.
