You can now view prior revisions of a comment by clicking on the “edited” dropdown in the comment’s header. Prior revisions are displayed as rendered prose diffs, and are visible to any user that can view the comment itself. If you need to remove sensitive information from the comment’s edit history, the comment author as well as any user with write access to the repository can remove the body of a prior revision when viewing the revision. For more information, see the documentation.
