* The `RequestAnimationFrame.step` and `stepTimeout` functions have been updated so that the new Frame is requested from raf before the main game step is called. This allows you to now stop the raf callback from within the game update or render loop. Fix #3952 (thanks @tolimeh)
* If you pass zero as the width or height when creating a TileSprite it will now use the dimensions of the texture frame as the size of the TileSprite. Fix #4073 (thanks @jcyuan)
* `TileSprite.setFrame` has had both the `updateSize` and `updateOrigin` arguments removed as they didn't do anything for TileSprites and were misleading.
* `CameraManager.remove` has a new argument `runDestroy` which, if set, will automatically call `Camera.destroy` on the Cameras removed from the Camera Manager. You should nearly always allow this to happen (thanks jamespierce)

* This method is called automatically by `CameraManager.remove` if that methods `runDestroy` argument is `true`, which is the default.

* Unless you have a specific reason otherwise, always use `CameraManager.remove` and allow it to handle the camera destruction,
