Features not included in one-time purchase version

What are the features not included in the one-time purchase version that you get with the subscription version? I would like to know what I am losing if I don't get the subscription.

I want an actual list. Does anyone know? Corel?

I currently have the Corel Standard 2021. I can't seem to find where I can edit the menus as I had in so many versions previous! Why would they take away something like that? Just to get "subscribers"?
