+Potentially Breaking Changes
+============================
+These changes are ones which we think may surprise users when upgrading to
+Clang |release| because of the opportunity they pose for disruption to existing
+code bases.

+- Clang will now correctly diagnose as ill-formed a constant expression where an
+ enum without a fixed underlying type is set to a value outside the range of
+ the enumeration's values. Due to the extended period of time this bug was
+ present in major C++ implementations (including Clang), this error has the
+ ability to be downgraded into a warning (via: -Wno-error=enum-constexpr-conversion)
+ to provide a transition period for users. This diagnostic is expected to turn
+ into an error-only diagnostic in the next Clang release. Fixes
+ `Issue 50055: `_.
+- ``-Wincompatible-function-pointer-types`` now defaults to an error in all C
+ language modes. It may be downgraded to a warning with

- Clang will now print more information about failed static assertions. In
particular, simple static assertion expressions are evaluated to their
compile-time value and printed out if the assertion fails.
