Hey, maybe they're new? Seems like the kind of thing I would ask a year ago lol. I'm getting the update now (on linux) and I just run different .jar/executable file for the different versions.
You can use flatpak version, it has updates. It's in the flathub official repo, so no additional configure is needed. If you won't mind supporting the author and using proprietary software... You can buy it on steam.
