Update conditions of older versions?

I keep getting FC notification saying “There is a new major release available through our website and you can get it for a small upgrade fee.”
However, I still use rather old FontCreator 9.1 Pro and the upgrade page does not mention this version at all:

  • FontCreator 15 Professional Edition - Upgrade from FontCreator 12, 13 or 14 Professional Edition

So, does version 9.1 qualify for the upgrade or not?

We don’t have special upgrades for outdated versions of our software, so we might need to provide better information.

However to show our appreciation, we will offer you a 25% discount. We will send you a PM.
