+- A long-standing bug (:ghc-ticket:`16893`) which can cause some applications
+ of ``unsafeCoerce`` to segmentation fault is only partially fixed in this
+ release. 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.
