Text.setShadow has had the default `color` value changed from `rgba(0,0,0,0)` to `rgba(0,0,0,1)` so it appears as a black shadow by default - before the alpha channel made it invisible.
Game.lockRender is a new property. If `false` Phaser will automatically render the display list every update. If `true` the render loop will be skipped. You can toggle this value at run-time to gain exact control over when Phaser renders. This can be useful in certain types of game or application. Please note that if you don't render the display list then none of the game object transforms will be updated, so use this value carefully.
