If customize-changed-options is new in Emacs 22, probably not ;-). But
yeah, the use of :version (and now :package-version) enables
customize-changed-options to show which options have been added, or have
had their default changed since the last (or selected) version. Think of
it as another way of reading NEWS.

I don't ;-). Until I started using CVS Emacs, I'd always used a more
up-to-date version than what was packaged with Emacs.
