So far on the 30th of December there has only been one update in Club Penguin History. That year is 2005. Astro Barrier was one of the few games you could play at the time, and it received an update with more levels. Here is the original blog post from Billybob notifying penguins about this update.
Hello Penguins,
I’m not sure if anyone has noticed yet, but we added several new levels to Astro Barrier. They are at the end of the game so you’ll have to play well to get to them, but if you make it that far, let us know what you think!
Until then, have a Happy New Year and Waddle On!
– Club Penguin Team
