Pay to own? – Aralon: Sword and Shadow Review

I’m afraid to update this. I bought this when crescent moon had this game. I bought it outright. So if I upgrade it, do I have to have a subscription to keep something I’ve paid for and owned for years? Trying to clarify because I’ve dismissed the update option for a long time..
