+- Added a `bascenev1.Quat` quaternion class. This can be useful for wrangling
+  the new rotation value on the prop node. For example, to point a prop in
+  random heading (rotating around the up axis) you can do:
+  `"rotate": bs.Quat.from_angles(heading=random.uniform(0.0, 360.0))`
 
 ### 1.7.63 (build 22870, api 9, 2026-06-08)
