• OAS 3 requestBody support for JSON request payloads
• Swagger 2 in: body and in: formData support
• path-level + operation-level parameter merge
• local $ref resolution for parameters, request bodies, and inline schemas
• header and cookie parameter support in generated commands and runtime requests
• better command generation for mixed OpenAPI 3 / Swagger 2 specs used in live regression tests

In practice this means ocli now handles a much larger set of POST/PUT/PATCH APIs correctly, including specs that define payloads outside simple query/path parameters.
