5.5.10 [2021.01.21]
* Fix a bug in which deriveBifoldable could generate code that
triggers -Wunused-matches warnings.
5.5.9 [2020.12.30]
* Explicitly mark modules as Safe or Trustworthy.
5.5.8 [2020.10.01]
* Fix a bug in which deriveBifunctor would fail on sufficiently
complex uses of rank-n types in constructor fields.
* Fix a bug in which deriveBiunctor and related functions would
needlessly reject data types whose two last type parameters appear
as oversaturated arguments to a type family.
5.5.7 [2020.01.29]
* Add Data.Bifunctor.Biap.
These PLIST files have been autogenerated by mk/haskell.mk using
HS_UPDATE_PLIST=yes during a bulk build. They will help to track changes
to the packages. The Haskell packages didn't have PLIST files because
their paths contained package hashes. These hashes are now determined by
mk/haskell.mk, which makes it easy to generate easy to read PLIST files.
A bifunctor is a type constructor that takes two type arguments and is
a functor in both arguments. That is, unlike with Functor, a type
constructor such as Either does not need to be partially applied for a
Bifunctor instance, and the methods in this class permit mapping
functions over the Left value or the Right value, or both at the same
time.
Formally, the class Bifunctor represents a bifunctor from Hask ->
Hask.
Intuitively it is a bifunctor where both the first and second
arguments are covariant.
You can define a Bifunctor by either defining bimap or by defining
both first and second.
