----------------------------
* [FEATURE] Add support for Jython with ``JythonSelectSelector``.
* [FEATURE] Add support for ``/dev/devpoll`` with ``DevpollSelector``.
* [CHANGE] Raises a ``RuntimeError`` instead of ``ValueError`` if there is no selector available.
* [CHANGE] No longer wraps exceptions in ``SelectorError``, raises original exception including
in timeout situations.
* [BUGFIX] Detect defects in a system that defines a selector but does not implement it.
* [BUGFIX] Can now detect a change in the ``select`` module after import such as when
``gevent.monkey.monkey_patch()`` is called before importing ``selectors2``.
