       binary upgrade on Linux.

       infinite time when using HTTP/2.

    *) Bugfix: when using HTTP/2 and the "limit_req" or \ 
"auth_request"
       directives client request body might be corrupted; the bug had

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.
