We've added the WCMS content endpoint in preview. Effectively we believe that this is what it will look like on full release, and are looking for feedback. We may add additional fields, and some of the data content may change, but we don't except we'll remove or significantly alter the existing schema.
As we come to the end of the year, thank you for providing feedback and suggestions using the GitHub issue tracker. We look forward to enabling you with more data, and wish you a joyful holiday season!
In the background we've updated some of the packages, nut, and bolts that power the API stack.
