I'm not really aware of any Haskell specific packaging practices, and
while I can't guarantee I'd have read it, if there is a reason to not
use the latest version of Haskell packages, it would be good to have
that reason set out in the docs [1].

I didn't look too carefully at the versions here, apart from the
ghc-doctest package, where I concluded that any related packages that
failed to build were already broken.
