@ -383,6 +383,7 @@ I deeply appreciate the help of the following people.
- [Aaron Burghardt](https://github.com/aburgh) implemented code to parse streams incrementally. Furthermore, he greatly improved the parser class by allowing the definition of a filter function to discard undesired elements while parsing.
- [Daniel Kopeček](https://github.com/dkopecek) fixed a bug in the compilation with GCC 5.0.
- [Florian Weber](https://github.com/Florianjw) fixed a bug in and improved the performance of the comparison operators.
- [Eric Cornelius](https://github.com/EricMCornelius) pointed out a bug in the handling with NaN and infinity values.
Thanks a lot for helping out!
