In the upcoming release, we are adding support for a new transport: meek. It is highly censorship resistant by converting stream into plain HTTP request/responses, allowing it to be reflected by any service that can relay HTTP request/responses.

在下个版本中将包含新传输协议 meek 。此协议可以将连接转换为一般 HTTP 请求回复， 以期使用任何支持转发 HTTP 请求的服务来转发 meek 连接，无需再担心 IP 被封锁， WebSocket CDN 被阻碍的问题。这个协议的速度很有限，不求跑满万兆带宽，只愿送抵万金家书。

v5.7.0 User Preview is released. (unstable version)
