Cloudpickle

=====

- Various fixes to support for Python 3.14 ([PR 545](
https://github.com/cloudpipe/cloudpickle/pull/545)).

=====

- Some improvements to make cloudpickle more deterministic when pickling
dynamic functions and classes, in particular with CPython 3.13.
([PR 524](https://github.com/cloudpipe/cloudpickle/pull/524) and
[PR 534](https://github.com/cloudpipe/cloudpickle/pull/534))

- Fix a problem with the joint usage of cloudpickle's `_whichmodule` and
`multiprocessing`.
([PR 529](https://github.com/cloudpipe/cloudpickle/pull/529))

=====

- 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 significantly, hopefully making it easier to contribute to and
maintain the project.
([PR 517](https://github.com/cloudpipe/cloudpickle/pull/517))

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