0.64.21

(feat): Introduce x-fern-discriminated extension to configure oneOf union behavior in OpenAPI specs.

1 # Example usage in OpenAPI schema
2 oneOf:
3   - $ref: '#/components/schemas/Circle'
4   - $ref: '#/components/schemas/Square'
5 x-fern-discriminated: false  # Treat as undiscriminated union

When x-fern-discriminated is set to false, the oneOf will be treated as an undiscriminated union instead of a discriminated union.
