Is there a specific reason why we=E2=80=99re following the Stackage release= s? Stackage is one step slower in getting the updates. The current Stackage= Nightly is 9.8.2, while Hackage has 9.10.1. Is this due to some stability = issues with Hackage? Regards, --=20 Divya Ranjan, Philosophy, Mathematics, Libre Software.
