 - The function ``__libcpp_verbose_abort()`` is now ``noexcept``, to match ``std::terminate()``. (The combination of
   ``noexcept`` and ``[[noreturn]]`` has special significance for function effects analysis.)
 
+- The ``_LIBCPP_DISABLE_AVAILABILITY`` macro that was used to force-disable availability markup has now been removed.
+  Whether availability markup is used by the library is now solely controlled at configuration-time.

@h-vetinari All of this doesn't explain why you can't use your own libc++ headers via `-nostdinc++`. Is it just that you've never though of that or is there an issue with using that strategy?
