# 1.1.0.1 - Drop `base-compat` dependency # 1.1 - Split `Semialign` into `Semialign` and `Zip`. - Rename old `Zip` into `Repeat` - i.e. current main hierarchy is - Remove `malign`, use `salign` or `alignWith mappend` where `Monoid` is necessary. - Add `Option` instances ```haskell instance Functor f => Semialign f where alignWith :: (These a b -> c) -> f a -> f b -> f c instance Semialign f => Align f where nil :: f a instance Semialign f => Zip f where zipWith :: (a -> b -> c) -> f a -> f b -> f c instance Zip f => Repeat f where repeat :: a -> f a ``` This biased choice, that `Semialign` is a super-class of `Zip` is motivated by the fact that - There's no `Semialign`-like class anywhere else, yet - `Zip` and `Repeat` are `Apply` (from `semigroupoids`) and `Applicative` with slightly more laws. I If you need only `Repeat` class, and your type isn't `Aling`able, maybe using `Applicative` is enough? # 1 Split out of `these` package.
