The latest incremental update of the open-source Nginx web server is out today and once again, HTTP/2 related fixes/improvement are part of the mix. Looking through 
the release noted two HTTP/2 changes are noteworthy:
*) Change: the "421 Misdirected Request" response now used when
rejecting requests to a virtual server different from one negotiated
during an SSL handshake; this improves interoperability with some
HTTP/2 clients when using client certificates.
*) Change: HTTP/2 clients can now start sending request body
immediately; the "http2_body_preread_size" directive controls size of
the buffer used before nginx will start reading client request body.
