* Deprecated `boost/core/is_same.hpp` and `boost::core::is_same`. The header will be removed in a future release.
Users are advised to use [@http://www.boost.org/doc/libs/release/libs/type_traits/doc/html/index.html Boost.TypeTraits]
or C++ standard library type traits instead.
* Marked `boost::ref` member functions and associated methods with `noexcept`.
