 Version         | Changes        |
 ----------------|----------------|
+**1.10.1** | Removed stdint.h, this doesn't exist on some really old compilers and we didn't really use it anyways. |
 **1.10.0** | Made HMM_Perspective use vertical FOV instead of horizontal FOV for consistency with other graphics APIs. |
 **1.9.0** | Added SSE versions of quaternion operations. |
 **1.8.0** | Added fast vector normalization routines that use fast inverse square roots.
