Currently Cantal has /v1/ API. We don't increment API version on backwards compatible changes. The following is deemed backwards-compatible:
- Addition of new resources
- Addition of new fields in structures
- Deprecation (but not removal) of resources
- Deprecation (but not removal) of fields in structures
- New formats of output (with some negotiation way, i.e. Accept header)
The (backwards-compatible) changes in API are listed here by version of a Cantal agent itself.
Until cantal reaches 1.0 it's only guaranteed to support single API version, after 1.0 we will support previous version of API for several releases after new API is introduced.
