OAS 3.1

[tfranzel]

WiP and preview of OAS 3.1 features. This is neither complete nor thoroughly tested but serves as a basis for discussion.

[johnthagen]

Just for reference (I was curious myself) the following generators do not yet support OpenAPI 3.1:

• [REQ] Support for OpenAPI Spec 3.1 OpenAPITools/openapi-generator#9083
• update to OpenAPI 3.1.x openapi-generators/openapi-python-client#585

Swagger UI (soon)?

• feat: OpenAPI 3.1 support swagger-api/swagger-ui#8367 (comment)
• OpenAPI 3.1 swagger-api/swagger-ui#5891

The latest FastAPI generates a 3.0.2 schema.

Should this be reflected on #378 ? What about JSON Schema Draft 2020-12 ( #1071 )?

UPTADE: I just saw that fix confirmation pending label has been added to #1071. I guess this means that it should be implemented as well, but is waiting for some kind of confirmation?

UPDATE 2: Release 0.27.0 mentions the added support for OpenAPI 3.1, so I'm pretty sure it should be reflected on the issue. I'd assume that with OpenAPI 3.1, the support for JSON Schema comes as well.
