Hi Jon: I recently faced this issue with a 2.0 upgrade. I don't know of any solution other than to prominently mention in large type in the release notes that the upgrade is a paid release.
Unfortunately, I had a few people writing in to complain after they blindly pressed "Upgrade" (which I myself and many people do by habit) and then finding either that they had to pay for an upgrade, or in rare instances, that the app no longer worked on Tiger. In all cases, a nicely written email turned people around from being angry to feeling that they got great customer service. Hope this helps. Best, John --- John C.
