Notes

HTTP/2 is only supported over TLS (HTTPS). See also the precursor of HTTP/2, the SPDY protocol, which has been deprecated and removed from most browsers, in favor of HTTP/2.

Partial support in Internet Explorer refers to being limited to Windows 10.
Partial support in Safari refers to being limited to OS X 10.11 El Capitan and newer.
Only supports HTTP/2 if the server supports protocol negotiation via ALPN.
