This update replaces the “[b]Ultimate Omelette[/b]” episode with the full “[b]Revenge of the Yolk[/b]” episode in CIU, directly playable from your Profile screen. This is a temporary and experimental feature, so enjoy it while you can, and report bugs here. Also, Christmas content has been added to mobile versions of the game. It will be automatically activated about 3 weeks before Christmas, or you can manually enable it now through Options → Seasonal Content.
