* ``twisted.web.client.Agent`` instances now use the same HTTPS policy by default as ``twisted.web.client.Agent``.
  It is possible to override this policy with the ``tls_context_factory`` argument, the equivalent to ``Agent``'s ``contextFactory=``.
* Added support for Python 3.11.
* No more ipaddress dependency
