@ -67,6 +67,7 @@ Significant API changes:
* Body.customSeparateCallback allows you to set your own callback when two Bodies need to separate rather than using the built-in method.
* Body.collideCallback allows you to set a callback that is fired whenever the Body is hit on any of its active faces.
* Body.allowCollision has been renamed to Body.checkCollision.
* Body.rebound is a boolean that controls if a body will exchange velocity on collision. Set to false to allow it to be 'pushed' (see new examples).
New features:
@ -167,6 +168,7 @@ Updates:
* Removed ArcadePhysics binding to the QuadTree, so it can now be used independantly of the physics system.
* Removed ArcadePhysics.preUpdate and postUpdate as neither are needed any more.
* Body.bottom and Body.right are no longer rounded, so will give accurate sub-pixel values.
* Fixed lots of documentation in the Emitter class.
