* 0.7
  - `strict-base-types` contents have been migrated to
      - `strict >=0.4`
      - `quickcheck-instances >=0.3.24`
      - `aeson >=1.5.3.0`
      - or `strict-lens >=0.4`

    This version has similar exposed API as 0.6.1,
    but we recommend to start using them directly (by specifying lower bounds).

* 0.6.1
  - Add contributions by Oleg Grenrus (@phadej)
    - Make 'Semigroup' instances available on all `base` versions.
    - Add 'Semigroup (Pair a b)' instance

* 0.6.0
  - Add contribution by Bas van Dijk (@basvandijk)
    - Add 'Semigroup' instance for base-4.9.0.0

* 0.5.0
  - Change the implementation of the 'Monoid Maybe' instance such that it is
    the same as the one for the lazy 'Maybe'; i.e., we now use

      Nothing `mappend` m       = m
      m       `mappend` Nothing = m
      Just x1 `mappend` Just x2 = Just (x1 `mappend` x2)

    instead of

      Nothing `mappend` _       = Nothing
      _       `mappend` Nothing = Nothing
      Just x1 `mappend` Just x2 = Just (x1 `mappend` x2)

* 0.4.0
  - Add contributions by Oleg Grenrus (@phadej)
    - Add 'Functor', 'Foldable', 'Traversable' for 'Pair'
    - bifunctors-5.1 compatibility
    - GHC 7.10.x -Wall cleaning
    - Add 'Hashable' instances for 'Pair', 'Maybe', and 'Either'.

* 0.3.0
  - Add 'Foldable', and 'Traversable' instances (thanks @jaspervdj)

* 0.2.3
  - started changelog
  - Make compatible with GHC 7.8 RC1
