Lots of things.

For example, before Pink, there didn't use to be any minor colors (the ones that split into their components). Now there are Pink (Red + White), Black (Blue + Purple), and Mythic (Red + Yellow). This was actually a cool addition in my opinion. However, they have changed the way that these colors worked many times, either because of bugs or just due to whim, especially the way they interact with the Diamond color. I have had to edit the Breeding Calculator's behavior many times and luckily there are nice people that test and post their results, or we could never keep up with all the unannounced changes.

The Passion Dragon with the Heart color was another new type. The Heart color didn't really interact with anything else, and the Passion Dragon had to be bred using specific parents (LeftHeart + RightHeart). The only way it interacted with normal breeding rules at all was that it appears as a pure color result when breeding two Diamond Dragons together. Also, the Passion Dragon was never intended to breed, so when a bug allowed people to use them as parents, lots of weird results happened until the bug was fixed. Since these were seasonal dragons for Valentine's, I'm okay with their breeding rules being a bit weird, though.

The most recent change involves dragons like Atlas and Peacock. They have a particular color, which suggests a particular set of color rules. They don't have specific parents, but they require specific colors that don't fit with the current known rules. Atlas can be bred with Mythic, Green, Blue instead of Red + Yellow. Peacock can be bred with Purple, Yellow instead of Red + Blue. Yet they also act like pure dragons for the most part. They seem to follow the interactions with Diamond properly. Also, when used as parents, they act like any other pure dragon of the same color.
