0.6.1

  • Fix regression in 0.6.0 which breaks the pickling of local function defined in a module, making it impossible to access builtins. (issue #211)

0.6.0

  • Ensure that unpickling a function defined in a dynamic module several times sequentially does not reset the values of global variables. (issue #187)

  • Restrict the ability to pickle annotations to python3.7+ (issue #193 and issue #196)

  • Stop using the deprecated imp module under Python 3. (issue #207)

  • Fixed pickling issue with singleton types NoneType, type(...) and type(NotImplemented) (issue #209)

0.5.6

  • Ensure that unpickling a locally defined function that accesses the global variables of a module does not reset the values of the global variables if they are already initialized. (issue #187)

0.5.5

  • Fixed inconsistent version in cloudpickle.__version__.

0.5.4

  • Fixed a pickling issue for ABC in python3.7+ (issue #180).

  • Fixed a bug when pickling functions in __main__ that access global variables (issue #187).

0.5.3

  • Fixed a crash in Python 2 when serializing non-hashable instancemethods of built-in types (issue #144).

  • itertools objects can also pickled (PR #156).

  • logging.RootLogger can be also pickled (PR #160).

0.5.2

  • Fixed a regression: AttributeError when loading pickles that hold a reference to a dynamically defined class from the __main__ module. (issue #131).

  • Make it possible to pickle classes and functions defined in faulty modules that raise an exception when trying to look-up their attributes by name.

0.5.1

  • Fixed cloudpickle.__version__.

0.5.0

  • Use pickle.HIGHEST_PROTOCOL by default.

0.4.4

  • logging.RootLogger can be also pickled (PR #160).

0.4.3

  • Fixed a regression: AttributeError when loading pickles that hold a reference to a dynamically defined class from the __main__ module. (issue #131).

  • Fixed a crash in Python 2 when serializing non-hashable instancemethods of built-in types. (issue #144)

0.4.2

  • Restored compatibility with pickles from 0.4.0.
  • Handle the func.__qualname__ attribute.

0.4.1

  • Fixed a crash when pickling dynamic classes whose __dict__ attribute was defined as a property. Most notably, this affected dynamic namedtuples in Python 2. (cloudpipe#113)
  • Cloudpickle now preserves the __module__ attribute of functions (cloudpipe#118).
  • Fixed a crash when pickling modules that don't have a __package__ attribute (cloudpipe#116).

0.4.0

  • Fix functions with empty cells
  • Allow pickling Logger objects
  • Fix crash when pickling dynamic class cycles
  • Ignore "None" mdoules added to sys.modules
  • Support WeakSets and ABCMeta instances
  • Remove non-standard __transient__ support
  • Catch exception from pickle.whichmodule()

0.3.1

  • Fix version information and ship a changelog

0.3.0

  • Import submodules accessed by pickled functions
  • Support recursive functions inside closures
  • Fix ResourceWarnings and DeprecationWarnings
  • Assume modules with __file__ attribute are not dynamic

0.2.2

  • Support Python 3.6
  • Support Tornado Coroutines
  • Support builtin methods

0.2.1

  • Packaging fix

0.2.0

  • Support method_descriptor
  • Support unbound instancemethods
  • Fixes for PyPy3
  • More support for pickling dynamic imports

0.1.0

Released on 2015-04-16 from the (real) clouds somewhere between Montréal and Atlanta.
