+- 4.3.35
+   - Fixed burstified recast code not sometimes throwing an exception in standalone IL2CPP builds.
+
 - 4.3.34 (2020-09-04)
    - Added a setter for the rotation property of all movement scripts (\reflink{IAstarAI.rotation}).
    - Fixed RichAI always teleporting to the closest point on the navmesh when the script is enabled even if \reflink{RichAI.canMove} is false.
