That's a possibility, but who ever looks at Guix version numbers? > Another more difficult option would be to do what responsible API > developers on the web do: to version their API and to make the API > version selectable. I don’t know *how* to do this elegantly, and That's an interesting idea which would also take care of similar situations in the future. One way to implement this is to have executables "guix1", "guix2" etc. Most users would then define an alias "guix" for interactive use, but hopefully script authors would use the versioned executables.
