 - A workaround for libstdc++4.7 has been removed. Note that 4.8.3 remains the oldest
   supported libstdc++ version.
 - Added ``!nonnull/!align`` metadata to load of references for better codegen.
-- Checking for int->enum conversions in constant expressions is more strict;
-  in particular, ``const E x = (E)-1;`` is not treated as a constant if it's
-  out of range. This impacts old versions of Boost.  (#GH143034)
