- update to 2.2.0:
* Improve compatibility with "nogil" Python and 3.11
* Fix compatibility with Python 3.11
* Add Python 3.10 to tox config
* Fix #440: Incorrect pickles for subclasses of generic classes

- Update to 2.1.0
* Support for pickling abc.abstractproperty, abc.abstractclassmethod, and abc.abstractstaticmethod. (PR #450)
* Support for pickling subclasses of generic classes. (PR #448)

and executed remotely without those local modules installed on the remote machine. (PR #417)
* Fix a side effect altering dynamic modules at pickling time. (PR #426)
* Support for pickling type annotations on Python 3.10 as per PEP 563 (PR #400)
* Stricter parametrized type detection heuristics in _is_parametrized_type_hint to limit false positives. (PR #409)
* Support pickling / depickling of OrderedDict KeysView, ValuesView, and ItemsView, following similar strategy for vanilla Python dictionaries. (PR #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)
