Hi Ricardo (and Guix), To avoid duplicating work, I wanted to let you know that I am working on updating the Haskell packages to their LTS 12.8 versions. This will go nicely with the new GHC 8.4.3.
I am keeping the work on a WIP branch that I have here: <https://gitlab.com/samplet/guix/tree/wip-haskell>. All the updates have commits, but there is still a lot of testing to do and build issues to resolve. I will keep you posted. If you have any issues with this approach now would be a good time to bring them up! :) -- Tim
