Adobe Director Hotfix3 is out and can be downloaded at : http://www.adobe.com/support/director/downloads.html

Some of the fixes/enhancements that went in ( we have tried out a few, and seems to be working ):

• RaycastAll( )  can now return a sorted list based on distance. This is quite a welcome enhancement. We had to follow a sorting algoritm to do this previosly. And yes it works as expected.
  lstraycast = member(”PhysicsWorld”).rayCastAll (vector(10,0,0),vector(0,0,1),[#sorted:#distance])
  ‐‐Returns an sorted list containing the above parameters
  put lstraycast
• Bug Fix: A new property for rigid bodies named axisAffinity has been added.
  axisAffinity when set to false rectifies the strange curving of rigid bodies when a small force is applied to them. By default axisAffinity is set to true. For performance reasons setting the property to false only for the required rigid body makes sense.
  rb.mass = 20
  rb.axisAffinity = false –removes the  curving effect for rigid body ‘rb”
  
• Bug Fix: Friction and Restitution were not being honored when the body was under collision or some specific scenario ( something like that, please add a comment if you know the complete story ) .
• And yes, the cloneModelFromCastMember( ) memory leak has been fixed !

Drop a comment if you have anything more to add.
