5.65.0

(feat): Add support for x-fern-global-parameters OpenAPI extension. Allows declaring global defaults for request body, query, header, and path fields that are set once at the SDK client level and injected at the declared wire location, with per-call values winning. IR bumped to 67.10.0.

5.64.3

(fix): Fix pages losing their sidebar when a top-level landing-page shares a slug with a page in versioned navigation. Reverts a 5.58.0 change: the top-level landing-page is no longer copied into each version, and product-level landing-page config is no longer applied to products inside product groups (restoring pre-5.58.0 rendering). landing-page in version files is unaffected.

5.64.2

(fix): OpenAPI import: an endpoint that declares both a body-bearing 2xx response and a 204 No Content response now correctly produces an optional success body, even when the 204 erroneously declares a response body. Per RFC 9110 a 204 cannot carry a body, so the declared 204 body is ignored (with a warning) and the success response type is wrapped optional. Previously the 204 was dropped and the return type stayed non-optional, so a real 204 (empty body) failed to decode in generated SDKs. Applies to both the legacy and v3 OpenAPI importers.
