 # Release log for the Libbulletjme project
 
-## Version 21.3.1 released on 12 September 2024
+## Version 21.3.2 released on 18 November 2024
 
 + Bugfix: `copyPcoProperties()` doesn't copy user indices
 + Bugfix:  logic error in `CollisionShape.nativeMargin()`
 + Publicized the `CollisionSpace.setLocalThreadPhysicsSpace()` method so
   per-thread physics spaces can nulled and garbage collected.
 + Added public method `Quaternion.isValidQuaternion()`.
++ Disallowed GImpact shapes with zero triangles.
 
 ## Version 21.2.1 released on 9 May 2024
