Re: [Haskell-cafe] Fwd: Fwd: Compatibility etiquette for apps, with cabal sandboxes and `stack`

As a developer, what should I import if my program/library works with e.g. the version range [1.20 .. 1.23]?

maybe change only that part of the namespace where api changed? also, why not publish less frequently? I mean, nothing stops anyone from making frequent changes to a library, but why not limit number of versions released to public?
