Hello, everyone! I have a wiki that has been under development for more than a decade. As a result, it contains some pages that haven't been updated in years and may be out of date. I'd like to display an age-related warning; if a page hasn't been edited in X years, there should be a message at the top indicating that some content may be out of date, and an edit might be needed. Is there an existing feature or plugin that would enable this functionality?
