It's the version from when you paid your annual subscription (or 12 monthly payments ago) plus any bugfixes.
So you buy 4.3.2 and you will always have access to 4.3.Z
2 months later they release 5.0.0. Your subscription let's you use 5.0.0. If you cancel your subscription then can go back to your perpetual version 4.3.Z
Assuming you keep paying, 12 months from its release if you pay monthly or you'll get a licence for whatever version is newest at the point you renew if you pay yearly

At least that's how it's supposed to work
At what point do I get to keep 5.0 instead?
