Cloudpickle

======================

=====

- Officially support Python 3.12 and drop support for Python 3.6 and 3.7.
Dropping support for older Python versions made it possible to simplify the
code base signficantly, hopefully making it easier to contribute to and
maintain the project.
([PR 515](https://github.com/cloudpipe/cloudpickle/pull/515))

- Fix pickling of dataclasses and their instances.
([issue 386](https://github.com/cloudpipe/cloudpickle/issues/386),
[PR 513](https://github.com/cloudpipe/cloudpickle/pull/513))

- Any color you like as long as it's black.
([PR 521](https://github.com/cloudpipe/cloudpickle/pull/521))

- Drop `setup.py` and `setuptools` in favor of `pyproject.toml` and `flit`.
([PR 521](https://github.com/cloudpipe/cloudpickle/pull/521))

=====

- Fix pickling of NamedTuple in Python 3.9+.
([issue 460](https://github.com/cloudpipe/cloudpickle/issues/460))

=====

- Fix support of PyPy 3.8 and later.
([issue 455](https://github.com/cloudpipe/cloudpickle/issues/455))

=====

- Support for pickling `abc.abstractproperty`, `abc.abstractclassmethod`,
and `abc.abstractstaticmethod`.
([PR 450](https://github.com/cloudpipe/cloudpickle/pull/450))

- Support for pickling subclasses of generic classes.
([PR 448](https://github.com/cloudpipe/cloudpickle/pull/448))

- Support and CI configuration for Python 3.11.
([PR 467](https://github.com/cloudpipe/cloudpickle/pull/467))

- Support for the experimental `nogil` variant of CPython
([PR 470](https://github.com/cloudpipe/cloudpickle/pull/470))

=====

- Python 3.5 is no longer supported.

- Support for registering modules to be serialised by value. This allows code
defined in local modules to be serialised and executed remotely without those
local modules installed on the remote machine.
([PR 417](https://github.com/cloudpipe/cloudpickle/pull/417))

- Fix a side effect altering dynamic modules at pickling time.
([PR 426](https://github.com/cloudpipe/cloudpickle/pull/426))

- Support for pickling type annotations on Python 3.10 as per [PEP 563](
https://www.python.org/dev/peps/pep-0563/)
([PR 400](https://github.com/cloudpipe/cloudpickle/pull/400))

- Stricter parametrized type detection heuristics in
_is_parametrized_type_hint to limit false positives.
([PR 409](https://github.com/cloudpipe/cloudpickle/pull/409))

- Support pickling / depickling of OrderedDict KeysView, ValuesView, and
ItemsView, following similar strategy for vanilla Python dictionaries.
([PR 423](https://github.com/cloudpipe/cloudpickle/pull/423))

- Suppressed a source of non-determinism when pickling dynamically defined
functions and handles the deprecation of co_lnotab in Python 3.10+.
([PR 428](https://github.com/cloudpipe/cloudpickle/pull/428))
