Likewise, any associative key-value containers (`std::map`, `std::multimap`, `std::unordered_map`, `std::unordered_multimap`) whose keys are can construct an `std::string` and whose values can be used to construct JSON types (see examples above) can be used to to create a JSON object. Note that in case of multimaps only one key is used in the JSON object and the value depends on the internal order of the STL container.

@ -483,6 +483,8 @@ I deeply appreciate the help of the following people.
- [Róbert Márki](https://github.com/robertmrk) added a fix to use move iterators and improved the integration via CMake.
- [Chris Kitching](https://github.com/ChrisKitching) cleaned up the CMake files.
- [Tom Needham](https://github.com/06needhamt) fixed a subtle bug with MSVC 2015 which was also proposed by [Michael K.](https://github.com/Epidal).
- [Mário Feroldi](https://github.com/thelostt) fixed a small typo.
- [duncanwerner](https://github.com/duncanwerner) found a really embarrassing performance regression in the 2.0.0 release.
Thanks a lot for helping out!
