This release only avoids this issue in the uses of ``unsafeCoerce`` + in ``Data.Typeable.Internal``, which was the proximate cause of + :ghc-ticket:`16893`. + + However, it is possible that this bug could manifest in user-code using + ``unsafeCoerce`` to perform dynamic type checks. See the :ghc-ticket:`ticket + <16893>` for details. + + We expect that this issue will be fixed in the next major release of GHC. + +- A long-standing bug (:ghc-ticket:`17760`) where some uses of the ``touch#`` + primop can be dropped by the simplifier is present in this release.
