所以有新的 streaming protocol 取代本來的 RCStream：「Get live updates to Wikimedia projects with EventStreams」。
這次新的 protocol 是走標準協定：
EventStreams is built on the w3c standard Server Sent Events (SSE). SSE is simply a streaming HTTP connection with event data in a particular text format. Client libraries, usually called EventSource, assist with building responsive tools, but because SSE is really just HTTP, you can use any HTTP client (even curl!) to consume it.
