My DS had an update in the app store just now; here are the details:
Version2.6.2
"What's New"
"Dragon Story is turning 5! Celebrate our 5th Anniversary with all new events, special prizes, and a few surprises along the way! Compete with friends in the Dragon Story community to earn amazing new and exclusive prizes. Our birthday celebration will even continue into May with an extra special Dragon Tales Event: Make a Wish!"
In the actual game though, nothing new happening.
