@@ -83,6 +83,7 @@ Notes:
 * `MultiScriptFile` is a new Loader FileType that allows you to load multiple script files into the document via the Phaser Loader, using the new `load.scripts` method. The difference between this and `load.script` is that you must pass an array of script file URLs to this method and they will be loaded in parallel but _processed_ (i.e. added to the document) in the exact order specified in the array. This allows you to load a bundle of scripts that have dependencies on each other.
 * `Key.getDuration` is a new method that will return the duration, in ms, that the Key has been held down for. If the Key isn't down it will return zero.
 * The `Container.setScrollFactor` method has a new optional argument `updateChildren`. If set, it will change the `scrollFactor` values of all the Container children as well as the Container. Fix #4466 #4475 (thanks @pinkkis @enriqueto)
+* There is a new webpack config `FEATURE_SOUND` which is set to `true` by default, but if set to `false` it will exclude the Sound Manager and all of its systems into the build files. Fix #4428 (thanks @goldfire)
