I'm pretty sure it's to the version that is 12 months behind when you stopped subscribing. You have to subscribe for an entire year to own the version when you started.
So if you subscribe for 12 months, and then cancel, you actually have to revert back to a version 1 year old. It's pretty messed up.
Plus the updates have REALLY been lacking. They have missed the quarterly releases regularly and it just feels like very little has actually been added.
