3.65.0

(feat): Add clientDefault support for headers, query parameters, and path parameters. When a parameter has a clientDefault value (set via the x-fern-default OpenAPI extension), the generated SDK uses that value as a fallback when the caller does not provide one. Parameters with clientDefault become optional in the client constructor and endpoint signatures.

3.64.2

(fix): Read the SDK version and package name from the IR’s publishConfig when available, not just for self-hosted orgs. This lets --version flow through to the generated package.json and X-Fern-SDK-Version header when the generator is invoked with output.location: local-file-system (where the generator exec output mode is downloadFiles and does not itself carry a version).
