Remove version information for scripts/stylesheets

Please detail for me the specific modifications MainWP uses to “Remove version information for scripts/stylesheets”

“Remove version information for scripts/stylesheets” was one of the flags as a result of MainWP Security Scan. I initiated a manual fix that should have resolved the issue, but it was not recognized by MainWP — since the security flag remained. I opted to click the “Fix” icon to resolve. That did the trick, but I have no idea what modifications MainWP made. Since there are varied methods to address any of the identified security flags, it would be nice to know specifics about how MainWP addresses them. I’d like to know specifically what files were modified in this instance.

Thank you.
