Changes with nginx 1.7.10 10 Feb 2015
*) Feature: the "use_temp_path" parameter of the "proxy_cache_path",
"fastcgi_cache_path", "scgi_cache_path", and "uwsgi_cache_path"
directives.
*) Feature: the $upstream_header_time variable.

testing directories.
Thanks to Damien Tournoud.
*) Bugfix: alerts "sendfile() failed" if the "sendfile" directive was
used on OS X; the bug had appeared in 1.7.8.

*) Bugfix: nginx could not be built with musl libc.
Thanks to James Taylor.
*) Bugfix: nginx could not be built on Tru64 UNIX.

*) Feature: variables support in the "proxy_cache", "fastcgi_cache",
"scgi_cache", and "uwsgi_cache" directives.
*) Feature: variables support in the "expires" directive.
*) Feature: loading of secret keys from hardware tokens with OpenSSL
engines.

and 206 status codes.
Thanks to Piotr Sikora.
*) Bugfix: the "TE" client request header line was passed to backends
while proxying.
*) Bugfix: the "proxy_pass", "fastcgi_pass", "scgi_pass", and
"uwsgi_pass" directives might not work correctly inside the "if" and
"limit_except" blocks.
*) Bugfix: the "proxy_store" directive with the "on" parameter was
ignored if the "proxy_store" directive with an explicitly specified
file path was used on a previous level.
*) Bugfix: nginx could not be built with BoringSSL.
Thanks to Lukas Tribus.
Changes with nginx 1.7.8 02 Dec 2014
*) Change: now the "If-Modified-Since", "If-Range", etc. client request
header lines are passed to a backend while caching if nginx knows in
advance that the response will not be cached (e.g., when using
proxy_cache_min_uses).
*) Change: now after proxy_cache_lock_timeout nginx sends a request to a
backend with caching disabled; the new directives
"proxy_cache_lock_age", "fastcgi_cache_lock_age",
"scgi_cache_lock_age", and "uwsgi_cache_lock_age" specify a time
after which the lock will be released and another attempt to cache a
response will be made.
*) Change: the "log_format" directive can now be used only at http
level.
*) Feature: the "proxy_ssl_certificate", "proxy_ssl_certificate_key",
"proxy_ssl_password_file", "uwsgi_ssl_certificate",
"uwsgi_ssl_certificate_key", and "uwsgi_ssl_password_file"
directives.
Thanks to Piotr Sikora.
*) Feature: it is now possible to switch to a named location using
"X-Accel-Redirect".

backend response header line.
Thanks to Piotr Sikora.
*) Bugfix: in the ngx_http_spdy_module.
Thanks to Piotr Sikora.
*) Bugfix: in the "ssl_password_file" directive when using OpenSSL
0.9.8zc, 1.0.0o, 1.0.1j.
*) Bugfix: alerts "header already sent" appeared in logs if the
"post_action" directive was used; the bug had appeared in 1.5.4.
*) Bugfix: alerts "the http output chain is empty" might appear in logs
if the "postpone_output 0" directive was used with SSI includes.
*) Bugfix: in the "proxy_cache_lock" directive with SSI subrequests.
Thanks to Yichun Zhang.
Changes with nginx 1.7.7 28 Oct 2014
*) Change: now nginx takes into account the "Vary" header line in a
backend response while caching.
*) Feature: the "proxy_force_ranges", "fastcgi_force_ranges",
"scgi_force_ranges", and "uwsgi_force_ranges" directives.
*) Feature: the "proxy_limit_rate", "fastcgi_limit_rate",
"scgi_limit_rate", and "uwsgi_limit_rate" directives.
*) Feature: the "Vary" parameter of the "proxy_ignore_headers",
"fastcgi_ignore_headers", "scgi_ignore_headers", and
"uwsgi_ignore_headers" directives.
*) Bugfix: the last part of a response received from a backend with
unbufferred proxy might not be sent to a client if "gzip" or "gunzip"
directives were used.

Thanks to Piotr Sikora.

anymore.
*) Feature: the "limit_conn_zone" and "limit_req_zone" directives now
can be used with combinations of multiple variables.
*) Bugfix: request body might be transmitted incorrectly when retrying a
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
if a shared SSL session cache or the same TLS session ticket key was
used for multiple "server" blocks (CVE-2014-3616).
Thanks to Antoine Delignat-Lavaud.
*) Change: now the "stub_status" directive does not require a parameter.
*) Feature: the "always" parameter of the "add_header" directive.

occurred during a DNS request.

*) Bugfix: a segmentation fault might occur in a worker process if the
"set" directive was used to change the "$http_...", "$sent_http_...",
or "$upstream_http_..." variables.
*) Bugfix: in memory allocation error handling.
Thanks to Markus Linnala and Feng Gu.
