 - The headers ``<experimental/algorithm>`` and ``<experimental/functional>`` have been removed, since all the contents
   have been implemented in namespace ``std`` for at least two releases.
 
+- The ``std`` clang module has been broken up into separate top level modules per public header.
+
 - The formatter specialization ``template<size_t N> struct formatter<const charT[N], charT>``
   has been removed. Since libc++'s format library was marked experimental there
   is no backwards compatibility option. This specialization has been removed
