Most notably, this affected dynamic [namedtuples](https://docs.python.org/2/library/collections.html#namedtuple-factory-function-for-tuples-with-named-fields)
in Python 2. (https://github.com/cloudpipe/cloudpickle/pull/113)
* Cloudpickle now preserves the `__module__` attribute of functions (https://github.com/cloudpipe/cloudpickle/pull/118/).
* Fixed a crash when pickling modules that don't have a `__package__` attribute (https://github.com/cloudpipe/cloudpickle/pull/116).
- Update to 0.4.0
* Fix functions with empty cells
