- Bugfix: Loading dicts with hashed keys could cause an error due to being loaded twice (thanks to georgeharker).
- Bugfix: IntEnums were not serialized with their names when `use_enum_name=True` (thanks to georgeharker).
- Bugfix: Named tuples did not use `typing.get_type_hints` for getting the types, causing trouble in future annotations (thanks to georgeharker).
