[Nix-dev] A Journey into our brand-new Haskell infrastructure: Part III

[Peter Simons]

Hi Miguel,

 > How does one add older versions of a package to hackage-packages.nix?

the list of "extra packages" is maintained in [1]. If you submit a patch or
pull request, then the additional version will show up in hackage-packages.nix.

Best regards,
Peter
