Describe stability

Describe the stability of your API or its various endpoints according to its maturity and stability, e.g. with prototype/development/production flags.

See the Heroku API compatibility policy for a possible stability and change management approach.

Once your API is declared production-ready and stable, do not make backwards incompatible changes within that API version. If you need to make backwards-incompatible changes, create a new API with an incremented version number.
