 Version         | Changes        |
 ----------------|----------------|
-**1.12.1** | Added extra parentheses around some macros |
-**1.12.0** | Added Unary Minus operator for `HMM_Vec2`, `HMM_Vec3`, and `HMM_Vec4`. |
-**1.11.1** | Added HMM_PREFIX macro to a few functions that were missing it. |
-**1.11.0** | Added ability to customize or remove the default `HMM_` prefix on function names by defining a macro called `HMM_PREFIX(name)`. |
-**1.10.1** | Removed stdint.h, this doesn't exist on some really old compilers and we didn't really use it anyways. |
+**1.10.2** | Introduced safe floating point comparison in HMM_EqualsVec2, HMM_EqualsVec3, HMM_EqualsVec4. SIMD'd HMM_EqualsVec4 comparison |
+**1.10.1** | Removed use of 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.
