They do upgrades from time to time, but since they added an island and habitats relatively recently, about the only thing left to do is feed dragons up to level 20 to get crowns on their heads. I've been feeding them for months to get most of them up to level 20 (I have duplicates of all the breeding pairs except the double rainbow). Someone calculated that it will take years to feed them all to level 20. They always do release new dragons, but I'd say the thrill of the chase wears off when you hit the highest level and buy all the habitats.
