Thanks for your response!
The current versions at my site are v5.2 (for the menus) and v4.0 (for the scroller). Those are available under a different license agreement than the older v2.0 scripts, and as far as I know, you don't permit custom licenses with Creative-Commons-like mandatory crediting rules for usage of scripts on JSS (which is fair enough from your perspective).
So the "v2.0" labelling of the scripts at JSS is meant to clear up the difference, as those are the versions you have already under a freely-redistributable license. If you keep the existing modification dates, people won't be too confused .
Anyway, if you don't want to append the version numbers, that's fine; my main request is just the Author URL update.
Cheers - Angus.
