4.96.0
(feat): Add optional baseProperties field to UndiscriminatedUnionTypeDeclaration in the IR schema.
Both the V3 importer and the legacy OpenAPI importer now extract sibling properties from
oneOf/anyOf schemas and populate baseProperties on undiscriminated unions.
4.95.0
(feat): Add placeholder field to auth scheme configuration (basic, bearer, header) for controlling
example values in dynamic code snippets. The fallback chain is: explicit placeholder > generic placeholder.
Configurable via Fern definition YAML and OpenAPI extensions (x-fern-basic, x-fern-bearer, x-fern-header).
