txtorcon 0.8.0 发布，异步Tor控制协议的实现

txtorcon是一个基于Twisted的异步Tor控制协议实现。 包括单元测试，例子，状态跟踪代码和配置抽象。Twisted是用Python编写的一个事件驱动的网络引擎。Tor是一个洋葱路由网络，设计用于改善人们在互联网上的隐私和匿名。

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);
