 ### WebSockets binary data
 
-Websockify supports all versions of the WebSockets protocol (Hixie and
-HyBi). The older Hixie versions of the protocol only support UTF-8
-text payloads. In order to transport binary data over UTF-8 an
-encoding must used to encapsulate the data within UTF-8.
+Starting with websockify 0.5.0, only the HyBi / IETF
+6455 WebSocket protocol is supported.
 
-With Hixie clients, Websockify uses base64 to encode all traffic to
-and from the client. This does not affect the data between websockify
-and the server.
-
-With HyBi clients, websockify negotiates whether to base64 encode
-traffic to and from the client via the subprotocol header
-(Sec-WebSocket-Protocol). The valid subprotocol values are 'binary'
-and 'base64' and if the client sends both then the server (the python
-implementation) will prefer 'binary'. The 'binary' subprotocol
-indicates that the data will be sent raw using binary WebSocket
-frames. Some HyBi clients (such as the Flash fallback and older Chrome
-and iOS versions) do not support binary data which is why the
-negotiation is necessary.
