I did some research on this prior to purchase, but clearly not enough. Web search claims new versions are backward compatible, but perhaps not?
In either case, the new Ubuntu 24 I'm running does not support .net 7, only 8. I'll go see if the Flatpak works, but it does look like you may start seeing compatibility issues.
I'll happily go deal with a few hurdles though, you people do amazing work and we appreciate all the effort you already put in.
