# 2.2.0

- Feature: Support composite schemas in `OpenApiSpex.schema`

structs defined with `OpenApiSpex.schema` will include all properties defined in schemas
listed in `allOf`. See the `OpenApiSpex.Schema` docs for some examples.

- Feature: Support composite and polymorphic schemas with `OpenApiSpex.cast/3`.
   -  `discriminator` is used to cast polymorphic shemas to a more specific schema.
   -  `allOf` will cast all properties in each included schema
   -  `oneOf` / `anyOf` will attempt to use each schema until a successful cast is made

# 2.1.1

- Fix: (#24, #25) Operations that define `parameters` and a `requestBody` schema can be validated.

# 2.1.0

- Feature: (#16) Error response from `OpenApiSpex.cast` when value contains unknown properties and schema declares `additionalProperties: false`.
- Feature: (#20) Update swagger-ui to version 3.17.0.
- Fix: (#17, #21, #22) Update typespecs for struct types.

# 2.0.0

Major version update following from API change in `OpenApiSpex.cast` and `OpenApiSpex.validate`.
When casting/validating all parameters against an `OpenApiSpex.Operation`, the complete `Plug.Conn` struct must now be passed, where the combined params map was previously accepted.
This allows `OpenApiSpex.cast` / `OpenApiSpex.validate` to check that the parameters are being supplied in the expected location (query, path, body, header, cookie).
In version 2.0.0, only unexpected query parameters will cause a 422 response from `OpenApiSpex.Plug.Cast`, this may be extended in future versions to detect more invalid requests.
