 ### Updates
 
-* The `backgroundColor` property of the Game Config is now used to set the CSS backgroundColor property of the game Canvas element. This avoids a `fillRect` call in Canvas mode and allows for 'punch through' effects to be created. If `transparent` is true, the CSS property is not set.
+* The `backgroundColor` property of the Game Config is now used to set the CSS backgroundColor property of the game Canvas element. This avoids a `fillRect` call in Canvas mode and allows for 'punch through' effects to be created. If `transparent` is true, the CSS property is not set and no background color is drawn in either WebGL or Canvas, allowing the canvas to be fully transparent.
 * You can now modify `this.physics.world.debugGraphic.defaultStrokeWidth` to set the stroke width of any debug drawn body, previously it was always 1 (thanks @samme)
 * `TextStyle.setFont` has a new optional argument `updateText` which will sets if the text should be automatically updated or not (thanks @DotTheGreat)
 * `ProcessQueue.destroy` now sets the internal `toProcess` counter to zero.

 * When using a Particle Emitter, the array of dead particles (`this.dead`) wasn't being filled correctly. Dead particles are now moved to it as they should be (thanks @Waclaw-I)
 * The `PathFollower.startFollow` method now properly uses the `startAt` argument to the method, so you can start a follower off at any point along the path. Fix #3688 (thanks @DannyT @diteix)
 * Static Circular Arcade Physics Bodies now render as circles in the debug display, instead of showing their rectangle bounds (thanks @maikthomas)
-* Changing the mute flag on an `HTML5AudioSound` instance, via the `mute` setter, now works, as it does via the Sound Manager (thanks @Waclaw-I)
