We’re excited to share a new UI for our API references:
We see this new interface as an improvement in clarity and discoverability of our (large!) set of references. We hope you like it 
All previous API reference paths are still available, but navigation will only take you to the new references. To ensure a seamless move over, we’ll continue to make both available then eventually phase out the previous user interface.
We’ll be continuing to polish the interface and spec files. If there’s anything you’d like to see us improve, let us know on this thread.
