Hi Didik,

Implementing of HTTP/2 in appreciated but not yet planned.
HTTP/1.1 is enough for many current tasks and will be enough in
foreseeable future, so HTTP/2 is not high priority.
HTTP/2 is much more complex comparing to HTTP/1.1. It require
multiplexing of data streams and encoding and decoding headers.
HTTP/2 will also require significant rise of amount of code and larger
resulting binary. Many functions, useful for HTTP/1.0 and HTTP/1.1 can't
be reused for HTTP/2 or will need rewrite.
We consider small binary size as advantage of MHD so HTTP/2-related code
must be implemented as disableable by configure switch.

Patches are always welcome but for so large change it will need a
separate branch with atomic commits and deep review.
