4.43.2

(fix): Fix OpenAPI importer to produce optional response types when an endpoint has both a 200 (with body) and a 204 (No Content) response. Previously the 204 response was silently ignored, causing generators to emit non-nullable return types and attempt deserialization on empty bodies. Both the v3 parser and v3.1 importer paths are fixed.

4.43.1

(fix): Fix OpenAPI importer stripping the discriminant property from shared allOf base schemas when they are used by oneOf discriminated union variants. Previously, if a base schema like Error was extended by both union members and standalone schemas, the discriminant property (e.g. code) would be removed from the base, causing downstream fern check errors on the union variant types.
