CHANGELOG-v3.50.md

@@ -674,6 +674,7 @@ Since v3.0.0 the Game Object `render` functions have received a parameter called
 * `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.
+* `Physics.Arcade.Body.setDamping` is a new method that allows you to set the `useDamping` property of a Body in a chainable way. Fix #5352 (thanks @juanitogan)
