There are a couple of changes more that arguably made the API worse:
* Event payloads changed to be “thin events”
* List endpoints became only eventually consistent
They also took away the “expand” parameter, which seems more useful that the new “include” one that works in some endpoints.
Generally their API design seems much more confusing and inconsistent nowadays. But to be fair their API is much bigger too. I guess it is hard to keep the same quality when you have so many engineers working on it.
