Security updates for Duplicate Cleaner 4

[Callistemon]

How much longer will Duplicate Cleaner 4 receive updates for security vulnerabilities? Should I uninstall it now that I have Duplicate Cleaner 5 installed and most of the regressions are fixed?

It's not an online program so security vulnerabilities aren't a thing. It uses the .NET Framework which will get updated automatically (if you have updates turned on). Major bugs will be fixed if present. There may be one small update still to go for 4.x.x regarding version 5 keys (helpful error messages!) and a small file filter bug.
