That's interesting, when did it change? There's no upgrade pricing available (yet?) and my ST2 licence still works.

If you bought ST2 license before the release of ST3 beta, I think you might need to pay for an upgrade once the final version 3 is released.

At some point during the beta release, they started selling ST3 license instead of ST2 licenses.
