Released v8.0.1

* Detect CAPaths in addition to CAFiles on platforms that provide them.
* Installing argparse or wsgiref will no longer warn or error - pip will allow
  the installation even though it may be useless (since the installed thing
  will be shadowed by the standard library).
* Upgrading a distutils installed item that is installed outside of a virtual
  environment, while inside of a virtual environment will no longer warn or
  error.
* Fix a bug where pre-releases were showing up in ``pip list --outdated``
  without the ``--pre`` flag.
* Switch the SOABI emulation from using RuntimeWarnings to debug logging.
* Rollback the removal of the ability to uninstall distutils installed items
  until a future date.
