Changes with nginx 1.10.2 18 Oct 2016
*) 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.
*) Bugfix: a segmentation fault might occur in a worker process when
using HTTP/2 and the "proxy_request_buffering" directive.
*) Bugfix: the "Content-Length" request header line was always
added to
requests passed to backends, including requests without body, when
using HTTP/2.
*) Bugfix: "http request count is zero" alerts might appear in
logs when
using HTTP/2.
*) Bugfix: unnecessary buffering might occur when using the
"sub_filter"
directive; the issue had appeared in 1.9.4.
*) Bugfix: socket leak when using HTTP/2.
*) Bugfix: an incorrect response might be returned when using the "aio
threads" and "sendfile" directives; the bug had appeared
in 1.9.13.
*) Workaround: OpenSSL 1.1.0 compatibility.
