Versioning Policy
This specification follows Semantic Versioning 2.0.0 as applied in SSF-SPEC-001:
| Segment | Meaning |
|---|---|
| MAJOR | A backwards-incompatible change to any message type, envelope structure, authentication scheme, connection model, or conformance requirement. |
| MINOR | Addition of new message types, fields, or capabilities that do not break existing conformant implementations. |
| PATCH | Editorial corrections, clarifications, and non-normative changes that do not affect conformance. |
This specification MUST declare the version of SSF-SPEC-001 to which it conforms. The current conformance target is SSF-SPEC-001 v1.0.0.
