* Added `stem.manual <api/manual.html>`_, which provides information available about Tor from `its manual <https://www.torproject.org/docs/tor-manual.html.en>`_ (:trac:`8251`)
* :func:`~stem.connection.connect` and :func:`~stem.control.Controller.from_port` now connect to both port 9051 (relay's default) and 9151 (Tor Browser's default) (:trac:`16075`)
* Added `support for NETWORK_LIVENESS events <api/response.html#stem.response.events.NetworkLivenessEvent>`_ (:spec:`44aac63`)
+ * Added :func:`~stem.control.Controller.get_custom_conf` to the :class:`~stem.control.Controller`
* Added :func:`~stem.control.Controller.is_user_traffic_allowed` to the :class:`~stem.control.Controller`
* Added the replica attribute to the :class:`~stem.response.events.HSDescEvent` (:spec:`4989e73`)
* IPv6 addresses could trigger errors in :func:`~stem.control.Controller.get_listeners`, :class:`~stem.response.events.ORConnEvent`, and quite a few other things (:trac:`16174`)
