aaron.ballman added a comment.
Herald added subscribers: kbarton, nemanjai.
Updated the failing tests caught during review (thank you!) and moved the
release notes around and reworded them somewhat for clarity.

+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.
+
+- The ``-Wimplicit-function-declaration`` and ``-Wimplicit-int`` warning
+ diagnostics are now enabled by default in C99, C11, and C17. As of C2x,
+ support for implicit function declarations and implicit int has been removed,
+ and the warning options will have no effect. Specifying ``-Wimplicit-int`` in
+ C89 mode will now issue warnings instead of being a noop.
+ *NOTE* these warnings are expected to default to an error in Clang 16. We
+ recommend that projects using configure scripts verify the results do not
+ change before/after setting ``-Werror=implicit-function-declarations`` or
+ ``-Wimplicit-int`` to avoid incompatibility with Clang 16.
