 Bug Fixes:
@@ -152,6 +153,7 @@ Bug Fixes:
 * Text that was fixedToCamera would 'jitter' if the world scrolled. Now works as expected across all fixed objects.
 * Fixed a bug where Sound.play wouldn't pick-up the local loop setting if not specified in the parameter.
 * Active animations now monitor if the game pauses, and resume normally when the game un-pauses (fixes #179)
+* Swapping between tabs will now pause the game correctly on mobile browsers (iOS7+)
