Constant	Value	Description
`QWebSocketProtocol::VersionUnknown`	`-1`	Unknown or unspecified version.
`QWebSocketProtocol::Version0`	`0`	hixie76 and hybi-00. Works with key1, key2 and a key in the payload. Attribute: Sec-WebSocket-Draft value 0. Not supported by QtWebSockets.
`QWebSocketProtocol::Version4`	`4`	hybi-04. Changed handshake: key1, key2, key3 ==> Sec-WebSocket-Key, Sec-WebSocket-Nonce, Sec-WebSocket-Accept Sec-WebSocket-Draft renamed to Sec-WebSocket-Version Sec-WebSocket-Version = 4. Not supported by QtWebSockets.
`QWebSocketProtocol::Version5`	`5`	hybi-05. Sec-WebSocket-Version = 5 Removed Sec-WebSocket-Nonce Added Sec-WebSocket-Accept. Not supported by QtWebSockets.
`QWebSocketProtocol::Version6`	`6`	Sec-WebSocket-Version = 6. Not supported by QtWebSockets.
`QWebSocketProtocol::Version7`	`7`	hybi-07. Sec-WebSocket-Version = 7. Not supported by QtWebSockets.
`QWebSocketProtocol::Version8`	`8`	hybi-8, hybi-9, hybi-10, hybi-11 and hybi-12. Status codes 1005 and 1006 are added and all codes are now unsigned Internal error results in 1006. Not supported by QtWebSockets.
`QWebSocketProtocol::Version13`	`13`	hybi-13, hybi14, hybi-15, hybi-16, hybi-17 and RFC 6455. Sec-WebSocket-Version = 13 Status code 1004 is now reserved Added 1008, 1009 and 1010 Must support TLS Clarify multiple version support. Supported by QtWebSockets.
`QWebSocketProtocol::VersionLatest`	`Version13`	Refers to the latest known version to QtWebSockets.
