The latest Silverfast (as of 2020/09/03) is 8.8.0r21. This application, which admittedly lives in a weird path of /Applications/Silverfast Application/Silverfast 8/Silverfast 8.app, has a version of "N/A" in JAMF Pro 10.22.1. Opening Get Info on the Silverfast 8.app reports the correct version as does the application "MacUpdate Desktop".
