 Occasionally, non-backwards compatible changes may be made in `minor` versions of the OAS where impact is believed to be low relative to the benefit provided.
 
+### Deprecation
+
+Certain fields or features may be marked **Deprecated**.
+These fields and features remain part of the specification and can be used like any other field or feature.
+However, OpenAPI Description authors should use newer fields and features documented to replace the deprecated ones whenever possible.
+
+At this time, such elements are expected to remain part of the OAS until the next major version, although a future minor version of this specification may define a policy for later removal of deprecated elements.

 ### Format
 
 An OpenAPI Document that conforms to the OpenAPI Specification is itself a JSON object, which may be represented either in [[RFC8259|JSON]] or [[YAML|YAML]] format.
