STEP BY STEP 3D API Versioning and Deprecation Policy

The public API uses URL versioning. The current stable version is /wp-json/stepbystep3d/v1.

Breaking changes create a new major version. Deprecated versions remain documented for at least 90 days before a Sunset date is announced. Clients should use the versioned URL from the OpenAPI specification and monitor the Deprecation, Sunset, and Link response headers when a version is scheduled to retire.
