Probably stating what is obvious and well-know but anyways:

- On the status page https://ghc.haskell.org/trac/ghc/wiki/Status/GHC-8.4.1 it would be good to have a link for "Phase 2 of the Semigroup-Monoid Proposal (Herbert Riedel)"

Good catch. I've added a link.

- Also IIRC we normally have a page on porting to the new release. It would be good to have that also when we have a chance.

Indeed, the migration page can be found here: https://ghc.haskell.org/trac/ghc/wiki/Migration/8.4. I've added a link to the 8.4 status page. Cheers, - Ben
