Quick question: is there any sort of changelog? there's plenty of tags, but just checking to make sure there's that.

[alexdlaird]

Not presently, I didn't see that as a requirement. The docs for the API haven't been public facing until now, so hasn't been necessary, but the API itself has been around for ~10 years (and live and in use by app.heliumedu.com, live docs at api.heliumedu.com), so updates always must be backwards compatible or additive only at this point. If I need a changelog though, happy to add one for going forward!

I think it might be beneficial to add one, so users see what breaking changes and/or fixes are made. Eager to hear others thoughts, but LGTM now.
