# Changelog
## Upcoming Changes
## Version 3.3.0
Refactor some internal operators for Vec3/Mat4 operations (like mult., sum,
etc.)
Added Mat3 and helper functions related to Mat3.
Implemented conversion from axis/angle to rotation matrix (Mat3).
Implemented conversion from rotation matrix (mat3) to axis/angle.
## Version 3.2.1
