......@@ -849,7 +849,9 @@ I deeply appreciate the help of the following people.
- [Steffen](https://github.com/koemeet) fixed a potential issue with MSVC and `std::min`.
- [Mike Tzou](https://github.com/Chocobo1) fixed some typos.
- [amrcode](https://github.com/amrcode) noted a missleading documentation about comparison of floats.
- [Oleg Endo](https://github.com/olegendo) reduced the memory consumption by replacing `<iostream>` with `<iosfwd>`
- [Oleg Endo](https://github.com/olegendo) reduced the memory consumption by replacing `<iostream>` with `<iosfwd>`.
- [dan-42](https://github.com/dan-42) cleaned up the CMake files to simplify including/reusing of the library.
- [Nikita Ofitserov](https://github.com/himikof) allowed for moving values from initializer lists.
Thanks a lot for helping out! Please [let me know](mailto:mail@nlohmann.me) if I forgot someone.
