cloneCD Tray V4.0 - updates?

I downloaded a trialversion of Clone CD - Tray V4.0, which looks very nice and works excellent. Before bying it, it would like to know whether you get updates for free, or that you have to purchase each new version again.

All updates of clonecd for the past couple of years have been free to registered users. Whilst there’s no guarantee that this will always remain so, there’s no reason to expect that the free update policy will change.
