How we built it

Deprecate and remove TLS Next Protocol Negotiation (removed)

NPN was the TLS extension used to negotiate SPDY (and, in transition, HTTP/2). During the standardization process, NPN was replaced with ALPN, published as RFC 7301 in July 2014. We intend to remove NPN at the same time as the SPDY removal.
