Yes, back in 2004 we did offer lifetime free updates for Professional Edition customers. We changed it to 1 year of updates a number of years ago, but indefinite access for the versions released during your free update period. But of course, we grandfathered in all licenses that came with lifetime free updates. I think when we started offering lifetime free updates back in 1998, we didn't expect to still be working on VueScan 27 years later!
