## 4.61.2

**`(fix):`** Re-add `@fern-api/generator-cli` to Python SDK Docker image. The CLI was inadvertently
removed in 4.60.1 when JS-based generators migrated to using the generator-cli JS API
directly. The Python generator still relies on the CLI binary via subprocess for
README.md and reference.md generation.

## 4.61.1

**`(fix):`** Fix `positional_single_property_constructors` breaking pydantic response deserialization.
The custom `__init__` now uses `@typing.overload` with a permissive `*args, **kwargs` runtime
signature, so pydantic can pass alias-keyed data freely during deserialization while still
allowing positional construction like `Wrapper("value")`.
