+- [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.
