Cowboy 2.0.0 has been released! This is the new stable version of Cowboy. There are no new releases planned for the 1.x version of Cowboy. The highlights from the release are: HTTP/2 support! Websocket compression! Much simpler, cleaner interface. No more weird errors just because you discard the Req object. A new low-level interface that receives all events from every set of request and response.
