One thing I definitely want to get in before the 8.0 release is:

* A fix for Trac #10716 [1] (adding strictness metadata to GHC generics). This feels like a natural counterpart for Trac #10697 [2] (reworking strictness information to Template Haskell), which currently has a Phab Diff in review [3]. I'd like for these to be released at the same time so that I can use Template Haskell to backport the machinery in generic-deriving [4]. In addition, I realized that my encoding of selector metadata is not very extensible at the moment, and this would give me a good excuse to fix it.

I've added these to "likely to land" list on the release status page.

Some things that I probably won't get in time for 8.0:

* Automatic derivation of Bifunctor/Bifoldable/Bitraversable, and of Eq1/Eq2/Ord1/Ord2/Read1/Read2/Show1/Show2. These would require resolving Trac #10448 [5] and #11135 [6] first, which might need more discussion. Not only that, but I still need to write up a proposal for how each of these classes would be derived, and there would need to be additional discussion on those points... All in all, it doesn't sound like something I could do in two weeks :)

Indeed this sounds like it might be a bit of a stretch.

* Making Generic1 kind-polymorphic, Trac #10604 [7]. The first step to achieving this was done recently [8], but unfortunately, I wasn't able to make the actual datatypes in GHC.Generics kind-polymorphic for unknown reasons (I'd still like to talk to Richard Eisenberg about this at some point). Not only that, but I'm not sure what the implications of making Generic1 poly-kinded would be yet. I'd like to talk to Andres Löh about this.

Good luck and let me know if I can be of assistance! Cheers, - Ben
