txtorcon 0.8.0 發布，異步Tor控制協議的實現

txtorcon是一個基于Twisted的異步Tor控制協議實現。 包括單元測試，例子，狀態跟蹤代碼和配置抽象。Twisted是用Python編寫的一個事件驅動的網絡引擎。Tor是一個洋蔥路由網絡，設計用于改善人們在互聯網上的隱私和匿名。

Release Notes: API change: ICircuitListener.circuit_failed, .circuit_closed and IStreamListener.stream_failed, .stream_closed, and .stream_detach all include any keywords in the notification method. Several cleanups + new example from lukaslueg (now pep8 clean!) launch_tor() can take a timeout (hellais); ipaddr is really optional now; TorState can create circuits without an explicit path; passwords use a password callback (possibly Deferred);
