Tool is outdated/insecure: targeted .NET Framework is 9 years out of support!

When will this tool be updated to target a supported version of .NET?

Certify is targeting .NET Framework 4.0, which lost support Jan 12, 2016 (nine years ago). Being out of support, this version has vulnerabilities that will not be patched. This presents security concerns. When Certify version 1.1.0 was released (2022-11-08 per your changelog), .NET Framework versions 4.6.2 through 4.8.1 were supported. Today, versions 4.7 through 4.8.1 are supported.
