Feature #9390: Support for the ALPN TLS extension

ALPN [1] is a successor [2] to NPN, support for which was added in 2.0.0 [3].

HTTP/2 [4] is using ALPN to negotiate protocol support, and the spec is moving fast -- it'd be great to have ALPN support in one of the upcoming Ruby releases. Current status of ALPN support in various TLS libraries and languages: https://github.com/http2/http2-spec/wiki/ALPN-Status. 

As a side note, for anyone interested, I have an implementation of draft-06 http/2 spec: https://github.com/igrigorik/http-2
