The WebSocket protocol is done...
Version 16 of the draft WebSocket protocol specification was just released and the HyBi mailing list announcement for this version contained the following:
Chairs and editors believe that this version is final (before the publication of the RFC). Thank you to everybody who helped to get this completed and for the stimulating discussions on the way.
Now feel free to discuss extensions, WebSocket 1.1, etc. :-).
There are no major differences between this and version 13 and the version number of the protocol itself stays at 13 so The WebSockets Option Pack supports everything that will be in the final RFC.
