Re: [Haskell-cafe] Why does cabal select base-3.0.3.2 when base-4.2.0.0 is available?

So what would be the fix, to set an upper bound on base? Is the general recommendation that all packages should specify upper bounds on all dependencies (if so why doesn't Cabal tell us?)?

Yes, that's the general recommendation. (upper and lower bounds)

I can see that this would make some sense as a package might be broken by an API change in its dependencies.

Exactly. That's why bounds on the versions of the dependencies are a good thing.

On the other hand I can also see it causing headaches occasionally...

Yes, but probably less headaches than packages eternally breaking because of API changes in the dependencies.

Thanks, Bjorn
