barbies-0.1.3.0: ChangeLog.md

# Changelog for barbies

## 0.1.3.0
  - Use both `Monoid` and `Semigroup` as constraints for the `Monoid` instance, so that this works with ghc 8.0 to 8.4 (Fraser Murray)

## 0.1.2.0
  - Use `Monoid` and not `Semigroup` as constraints for the `Monoid` instance

## 0.1.1.0
  - Add `instance Semigroup (Barbie b)` to go along the `Monoid` instance

## 0.1.0.1
  - Works under GHC 8.0.2, but notice one needs to use empty instance
    declarations, because ghc chokes on `deriving` clauses.
