API Versioning & Deprecation Policy
A defensible default policy for evolving your API safely: how to version, what counts as breaking, and exactly how to deprecate and sunset.
- ✓ URI vs header versioning and how semver maps to your API
- ✓ A breaking vs non-breaking change table with how to ship each
- ✓ A 4-stage deprecation lifecycle with Deprecation and Sunset headers
- ✓ A fill-in policy block for your support window and notice periods
