- Add ``URec``, ``UAddr``, ``UChar``, ``UDouble``, ``UFloat``, ``UInt``, and ``UWord`` to
``GHC.Generics`` as part of making GHC generics capable of handling unlifted
types (:ghc-ticket:`10868`)
- Expand ``Floating`` class to include operations that allow for better
precision: ``log1p``, ``expm1``, ``log1pexp`` and ``log1mexp``. These are not
available from ``Prelude``, but the full class is exported from ``Numeric``.
- Add ``Data.List.NonEmpty`` and ``Data.Semigroup`` (to become
super-class of ``Monoid`` in the future). These modules were
provided by the ``semigroups`` package previously. (:ghc-ticket:`10365`)
- The constraints of various functions in ``Control.Monad`` have been
generalized from ``Monad`` to ``Applicative`` including ``filterM``,
``zipWithM`` and ``replicateM_`` (see :ghc-ticket:`10168`).
- Add ``GHC.TypeLits.TypeError`` and ``ErrorMessage`` to allow users
to define custom compile-time error messages.
- The ``Generic`` instance for ``Proxy`` is now poly-kinded (see :ghc-ticket:`10775`)
- The ``IsString`` instance for ``[Char]`` has been modified to eliminate
ambiguity arising from overloaded strings and functions like ``(++)``.
- Move ``Const`` from ``Control.Applicative`` to its own module in
``Data.Functor.Const``. (see :ghc-ticket:`11135`)
- Enable ``PolyKinds`` in the ``Data.Functor.Const`` module to give ``Const``
the kind ``* -> k -> *`` (see :ghc-ticket:`10039`).
