• Dropped support for Python 2.7 and 3.5 and PyPy 2.
• Added pyupgrade pre-commit hook.
• Added black pre-commit hook and reformatted codebase.
• Updated pre-commit hooks.
• Replaced custom flake8, sort, and check-manifest Github Action jobs with a generic pre-commit job.
• Dropped the moneyed.localization module that was deprecated and announced for removal in 1.0.
• Added type hints along with a mypy pre-commit hook.
• Added action for building and publishing releases, along with the check-github-workflows pre-commit hook for validating Github Action workflow files.
• Removed undocumented DEFAULT_CURRENCY and DEFAULT_CURRENCY_CODE constants, and change to make instantiating Money without providing a currency a type error. This used to result in an object with a made-up "XYZ" currency, which could lead to surprising behaviors and bugs.

• Moved to use setuptool's declarative packaging config and PEP 517 isolated builds.
