@ -276,5 +276,7 @@ C++11 support has resulted in some breaking changes:
* Remove `BOOST_UNORDERED_DEPRECATED_EQUALITY` warning.
* Simpler implementation of assignment, fixes an exception safety issue
for `unordered_multiset` and `unordered_multimap`. Might be a little slower.
* Stop using return value SFINAE which some older compilers have issues
with.
