Replay now allows you to see comments from previous versions by selecting 'Previous Versions' at the top of the comments right rail. When comments from previous versions are visible, you can hover over the version on a prior comment, and you'll have the option to click the version where it was initially left to see the original comment.
If you want to share with others and you do
not
want them to see all of the comments from prior versions, you can change this setting in your share settings by clicking manage settings when you create a share link. And for those of you using our integrations, this will also means that when you import comments as markers you no longer will run into the issue of re-importing lengthy threads that were previously resolved.
