Pylint

New beta release following a performance fix in the new pointless exception statement checks in https://github.com/PyCQA/pylint/issues/8073 and a false positive fixed in the unreleased consider-using-augmented-assign check in https://github.com/PyCQA/pylint/pull/8088. We're also using the latest version of astroid (2.13.3).

The complete changelog will be published when the actual 2.16.0 is released.

This is the beta version of 2.16.0 the complete changelog will be published when the actual 2.16.0 is released.

In 2.16.0 we added aggregation and composition understanding in ``pyreverse``, and a way to clear the cache in between run in server mode (originally for the VS Code integration). Apart from the bug fixes there's also a lot of new checks, and new extensions that have been asked for for a long time that were implemented.

If you want to benefit from all the new checks load the following plugins:

pylint.extensions.dict_init_mutate,
pylint.extensions.dunder,
pylint.extensions.typing,
pylint.extensions.magic_value,

We still welcome any community effort to help review, integrate, and add good/bad examples to the doc for https://github.com/PyCQA/pylint/issues/5953. This should be doable without any ``pylint`` or ``astroid`` knowledge, so this is the perfect entrypoint if you want to contribute to ``pylint`` or open source without any experience with our code!

Last but not least clavedeluna and nickdrozd became triagers, welcome to the team !
