- [Corbin Hughes](https://github.com/nibroc) fixed some typos in the contribution guidelines.
- [twelsby](https://github.com/twelsby) fixed the array subscript operator, an issue that failed the MSVC build, and floating-point parsing/dumping. He further added support for unsigned integer numbers.
- [Volker Diels-Grabsch](https://github.com/vog) fixed a link in the README file.
- [msm-](https://github.com/msm-) added support for american fuzzy lop.

Thanks a lot for helping out!
