Indeed, I have checked and the new version is 6.2.1, however, if you want to update the details, simply look for the “Suggest a correction” link found on the application's page and use it to suggest updated links, screenshots, version information, etc. Note that you must be a registered user at Software/Mac Informer in order to do that.
