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.

Changes with nginx 1.9.13 29 Mar 2016
*) Change: non-idempotent requests (POST, LOCK, PATCH) are no longer
passed to the next server by default if a request has been sent to a

Windows.
Changes with nginx 1.9.12 24 Feb 2016

response processing if the "resolver" directive was used, allowing an
attacker who is able to forge UDP packets from the DNS server to
cause segmentation fault in a worker process (CVE-2016-0742).

processing if the "resolver" directive was used, allowing an attacker
who is able to trigger name resolution to cause segmentation fault in
a worker process, or might have potential other impact
(CVE-2016-0746).
*) Security: CNAME resolution was insufficiently limited if the
"resolver" directive was used, allowing an attacker who is able to
trigger arbitrary name resolution to cause excessive resource
consumption in worker processes (CVE-2016-0747).

FastCGI request to the next upstream server.
*) Bugfix: in logging to syslog.
Changes with nginx 1.7.5 16 Sep 2014
*) Security: it was possible to reuse SSL sessions in unrelated contexts
