A detailed protocol test suite report [58] lists the conformance of those browsers to specific protocol aspects. An older, less secure version of the protocol was implemented in Opera 11 and Safari 5, as well as the mobile version of Safari in iOS 4.2. [59] The BlackBerry Browser in OS7 implements WebSockets.
