The most effective way to evolve your API without breaking changes is to follow effective API change management principles. The Semantic standards as still valid and you could use it internally to run multiple APIs or microservices. You are delivering data to the public in some fashion and you need to communicate when you change the way that data is delivered. Your API versioning scheme just provided you some (weak) forward-compatibility guarantees in addition to (strong) backward-compatibility ones.
