Possible to add Proton-GE 5.21-GE-1?

Is it possible to add Proton-GE 5.21-GE-1 to ProtonUp?

I'm trying to test Jamestown+ which is reported to work on that version but I don't see it available as an option to install.

This seems to be right, interesting one. I'll investigate on this.

In the meantime, come over to my fork and recreate your issue there. ProtonUp-ng is working with the new versioning scheme.
