Changelog

0.64.24

(fix): When a part in a multipart form request has Content-Type: application/json in OpenAPI or Fern Definition, interpret it as style: json.

0.64.23

(fix): Global headers are now used to create endpoint examples. When building endpoint examples, global headers are automatically included in the headers section of each example. This ensures that all endpoints have consistent header examples that match the global header configuration.

0.64.22

(feat): Make proto file target field optional in generators.yml

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.
