As Pete said updates are easy.

Sorry about that, after my son having done mine i can understand why you would be have been excited about a new update. Huge improvement, most noticeable at first where the bulbs being vastly different colours, remembering that i hadn't done any updates and alot of my bulbs where boring white.
