CHANGELOG.md

@@ -95,6 +95,7 @@ Notes:
 * `Camera.startFollow` will now ensure that if the Camera is using bounds that the `scrollX` and `scrollY` values set after first following the Game Object do not exceed the bounds (thanks @snowbillr)
 * Creating a Tween with a `duration` of zero would cause the tweened object properties to be set to `NaN`. Now they will tween for one single frame before being set to progress 1. Fix #4235 (thanks @BigZaphod)
 * The First frame of a Texture would take on the appearance of the second frame in a Sprite Sheet created from trimmed Texture Atlas frames. Fix #4088 (thanks @Cirras)
+* `Tween.stop` assumed that the parent was the TweenManager. If the Tween has been added to the Timeline, that was not true and the stop method crashed (thanks @TadejZupancic)
