0.46.19

(fix): If a schema in OpenAPI or AsyncAPI has additionalProperties: true then the Fern CLI will now respect bringing in example properties that are not defined in the schema. Previously, the CLI would skip them.

0.46.18

(fix): If an object or request is annotated with extra-properties: true then the user can provide an example that includes extra properties that are no longer in the schema.

For example, check out this fern definition
