 * The Mouse Manager class has been updated to remove some commented out code and refine the `startListeners` method.
 * The following Key Codes have been added, which include some missing alphabet letters in Persian and Arabic: `SEMICOLON_FIREFOX`, `COLON`, `COMMA_FIREFOX_WINDOWS`, `COMMA_FIREFOX`, `BRACKET_RIGHT_FIREFOX` and `BRACKET_LEFT_FIREFOX` (thanks @wmateam)
 * When enabling a Game Object for input it will now use the `width` and `height` properties of the Game Object first, falling back to the frame size if not found. This stops a bug when enabling BitmapText objects for input and it using the font texture as the hit area size, rather than the text itself.
+* `Pointer.smoothFactor` is a float-value that allows you to automatically apply smoothing to the Pointer position as it moves. This is ideal when you want something smoothly tracking a pointer in a game, or are need a smooth drawing motion for an art package. The default value is zero, meaning disabled. Set to a small number, such as 0.2, to enable.
+* `Config.inputSmoothFactor` is a new property that allows you to set the smoothing factor for all Pointers the game creators. The default value is zero, which is disabled. Set in the game config as `input: { smoothFactor: value }`.
+* `InputManager.transformPointer` has a new boolean argument `wasMove`, which controls if the pointer is being transformed after a move or up/down event.
