This year already has five years... Is there still plans on supporting HTTP/2?

This would be fantastic to see, any ideas/strategy on how to go about implementation?

At first sight, there are two basic things to do:

• include http/2 protocol (sending and receiving frames, etc) to the server. This is something I did recently for other reasons (client side, but server side turned up to be trivial after that) and is relatively straightforward.
• signal to clients that you support http2 so they use it. Unfortunately, this is done in most practical cases (browsers) in TLS negotiation, and as far as I can see this is outside of woo scope - so it might turn up to be the hard part (but then again, maybe someone knows solution).

And after that, of course, small work to tune the code so that it really is /fastest web server written in any programming language./ - precompile headers, handle window sizes, ...
