webrtc support on safari 11 for ios

Dear All,

Apple annouced the support of webrtc on safari 11 for ios:

https://developer.apple.com/library/content/releasenotes/General/WhatsNewInSafari/Safari_11_0/Safari_11_0.html

I have updated the ios to version 11 final, but using safari to connect to a standard webrtc site, receive on the browser itself the message webrtc not supported.

Can You say if this is available yet or We need to wait for a further update and when You think available?

Thank You so much

Best regards
