Next conceptMinor versus patch increments for backward-compatible API changes

Explainer

Anypoint Exchange versions API assets with semantic versioning, written as major.minor.patch. A new major version signals a breaking change, which is a change that forces existing API consumers to change their own side of the integration. Changes that keep working for current consumers should be released as minor or patch versions instead.
Core information
  • Exchange asset versions use the Semantic Versioning model of major, minor and patch releases, but build metadata is not supported. For example, in version 2.4.6 the major version is 2.x.x, the minor version is 2.4.x and the patch version is 2.4.6.
More details and nuances
  • A change can be breaking even when the interface structure stays the same. A change to quality of service, such as response time or availability, might not be backward compatible with the applications that use the API, so it can call for a new major version and a new API version.
