### p2.js 0.6.0 Changes and New Features
* DistanceConstraint signature changed to take the new localAnchors.
* RevoluteConstraint signature changed to include worldPivot
* RevoluteConstraint signature changed to include worldPivot.
* P2.Body now uses the new Body.type value instead of Body.motionState, however as P2.Body already have a property called `type` we have left the `motionState` getter/setter in for now.
* World.enableBodySleeping has been removed and replaced with World.sleepMode.
* Phaser P2.Springs are now LinearSprings by default.
