The promised new dungeon thingy is a major change to CC.
All the stuff listed here for this patch is (relatively) very minor adjustments, change a number here or there kinda stuff.
So looks like IGG decided to go ahead and put in the Christmas stuff, new Heroes, gifts, fixes, etc. now.
Could have rushed the New Dungeon junk out, or made all this Christmas stuff wait for that to be tweeked so maybe late Dec or Jan...
I say they made the right choice to skip the new stuff for now.
