There was NEVER a version without a link to remove all broken bookmarks so it's not possible at all that you don't have this feature.

For warnings you can see the original URL and the corrected URL, so I don't know what is not clear for you.

You can see in the add-on manager which version is installed.

Please don't give bad reviews only because you don't understand the user interface. You can ask questions on GitHub. But this add-on is working and giving bad reviews for working add-ons is really NOT okay…
