-[h4 Boost 1.60.0 ???]
+[h4 Boost 1.64.0]
+
+* Added new trait __make_void.
+
+[h4 Boost 1.60.0]
 
 * Refactored traits to depend only on Boost.Config.  Greatly simplified code to improve readability and remove workarounds for old compilers no longer supported.
 * Fix __decay to follow C++11 semantics, see [@https://svn.boost.org/trac/boost/ticket/7760 #7760].
