- Cosmetic: replace tabs with blanks, strip trailing white space,
  and update copyright headers with spec-cleaner.
* Fri Jul 13 2018
- Update free to version 5.1.
  5.1 [2018.07.03]
  - ---------------
  * Generalize the type of `_Free`.
  * Allow building with `containers-0.6`.
  * Avoid incurring some dependencies when using recent GHCs.
  5.0.2 [2018.04.25]
  - -----------------
  * Add `Generic` and `Generic1` instances where possible.
* Mon May 14 2018
- Update free to version 5.0.2.
  * Add a `Semigroup` instance for `IterT`.
  * Add `MonadFail` instances for `IterT` and `FreeT`.
  * Add a `Comonad` instance for the free `Applicative`, `Ap`.
  * Add `Control.Monad.Free.Ap` and `Control.Monad.Trans.Free.Ap` modules, based
    on the "Applicative Effects in Free Monads" series of articles by Will
  * Derive `Data` instances for `Free` and `Cofree`.
  * `Control.Monad.Free.TH` now properly supports `template-haskell-`. In
    particular, it now supports `GadtC` and `RecGadtC`, which are new
    `template-haskell` forms for representing GADTs.
  * Add `telescoped_`, `shoots`, and `leaves` to `Control.Comonad.Cofree`
  * Add the `Control.Applicative.Free.Fast` module, based on Dave Menendez's
    article "Free Applicative Functors in Haskell"
  * Add `foldFreeT` to `Control.Monad.Trans.Free`
  * Improve the `foldMap` and `cutoff` functions for
    `Control.Monad.Free.Church.F`, and add a `Traversable`
  * Add a `MonadBase` instance for `FreeT`
  * Add a performance test comparing Free and Church interpreters
  * The use of `prelude-extras` has been removed. `free` now uses the
    `Data.Functor.Classes` module to give `free`'s datatypes instances of `Eq1`,
    `Ord1`, `Read1`, and `Show1`. Their `Eq`, `Ord`, `Read`, and `Show` instances
    have also been modified to incorporate these classes. For example, what
    previously existed as:
    instance (Eq (f (Free f a)), Eq a) => Eq (Free f a) where
    has now been changed to:
    instance (Eq1 f, Eq a) => Eq (Free f a) where
  * Remove redundant `Functor` constraints from `Control.Alternative.Free`
Version: 4.12.4-bp150.2.4
* Thu Aug 03 2017
- Updated with latest spec-cleaner version 0.9.8-8-geadfbbf.
Version: 4.12.4-2.3

- Update to version 4.12.4 revision 0 with cabal2obs.
* Mon Jan 18 2016
- update to 4.12.4
  * Add instances for ExceptT: like ErrorT, but without an Error constraint.
  * Support containers
  * Support transformers 0.5
  * Removed a number of spurious class constraints.
  * Support comonad 5
* Thu Aug 06 2015
- update to 4.12.1
  * Add instances of MonadCatch and MonadThrow from exceptions to FT, FreeT and IterT.
  * semigroupoids 5, profunctors 5, and bifunctors 5 support.
