 * `SpinePlugin.gameDestroy` is a new method that is called if the Game instance emits a `destroy` event. It removes the Spine Game Objects from the factory and disposes of the Spine scene renderer.
 * `SpineFile` will now check to see if another identical atlas in the load queue is already loading the texture it needs and will no longer get locked waiting for a file that will never complete. This allows multiple skeleton JSONs to use the same atlas data. Fix #5331 (thanks @Racoonacoon)
 * `SpineFile` now uses a `!` character to split the keys, instead of an underscore, preventing the plugin from incorrectly working out the keys for filenames with underscores in them. Fix #5336 (thanks @Racoonacoon)
+* `SpineGameObject.willRender` is no longer hard-coded to return `true`. It instead now takes a Camera parameter and performs all of the checks needed before returning. Previously, this happened during the render functions.

 * `Matrix4.getInverse` is a new method that takes a Matrix4, copies it to the current matrix, then returns the inverse of it.
 * `WebGLRenderer.instancedArraysExtension` is a new property that holds the WebGL Extension for instanced array drawing, if supported by the browser.
 * `WebGLRenderer.vaoExtension` is a new property that holds a reference to the Vertex Array Object WebGL Extension, if supported by the browser.
+* `CameraManager.getVisibleChildren` is a new method that is called internally by the `CameraManager.render` method. It filters the DisplayList, so that Game Objects that pass the `willRender` test for the given Camera are added to a sub-list, which is then passed to the renderer. This avoids the renderer having to do any checks on the children, it just renders each one in turn.
