EDIT: I think relaxation of https://github.com/ekmett/semigroups/issues/101 would make older GHCs have (failing) installing plans with contravariant-1.5.4 and transformers-0.6, so probably bette to decide what to do with semigroups first.

Sigh. I had a feeling that I forgot something. See #69.

phadej commented 3 years ago

No worries. I hope I don't find many more transformers-0.6 issues (I'll try to publish these, indexed-traversable and strict revisions ASAP).

EDIT: revisions for above packages are now made.

RyanGlScott commented 3 years ago

Fixed in 56e52f7. I've uploaded contravariant-1.5.5 to Hackage with these changes.
