What is current WINDOW version 2.2.1 or 2.5?

The subject line says it all - thanks

I’m on 2.2.1 (paid version but I don’t remember being offered anything else so I am confused since on Fractal Audio forums there is discussion about version 2.5??)

Hello Larry, welcome here :slightly_smiling_face:
I assume you are on Mac or PC as you are referring to version 2.2.1.
2.5 is the version for iOS.
