## Changes in Boost 1.79 ## Changes in Boost 1.79
* Added a `throw_exception_from_error` overload for `std::error_code`. * Added a `throw_exception_from_error` overload for `std::error_code`.
* Added a `boost::source_location` parameter to `throw_exception_from_error`.
* `result<T>::value` now automatically supplies `BOOST_CURRENT_LOCATION` to
`throw_exception_from_error` via a default argument.
