- Update to 0.8.1:
* Fix a bug (already present before 0.5.3 and re-introduced in 0.8.0) affecting relative import instructions inside depickled functions (issue #254)

- Update to 0.8.0:
* Add support for pickling interactively defined dataclasses. (issue #245)
* Global variables referenced by functions pickled by cloudpickle are now unpickled in a new and isolated namespace scoped by the CloudPickler instance. This restores the (previously untested) behavior of cloudpickle prior to changes done in 0.5.4 for functions defined in the __main__ module, and 0.6.0/1 for other dynamic functions.
