## 4.64.0

**`(feat):`** Add `omit_fern_headers` configuration option. When enabled, Fern platform headers
(X-Fern-Language, X-Fern-SDK-Name, X-Fern-SDK-Version, X-Fern-Runtime,
X-Fern-Platform, User-Agent) are omitted from generated SDK requests.

## 4.63.6

**`(fix):`** Fix wire test generation for types with required fields missing from examples.
When an OpenAPI example omits required fields on a nested object type, the generated
test code now synthesizes reasonable default values (e.g., `""` for strings, `1` for
integers, `[]` for lists) instead of emitting empty constructors like `ClassName()`
that cause Pydantic `ValidationError` at runtime.
