Changes with nginx 1.11.5 11 Oct 2016
*) Change: the --with-ipv6 configure option was removed, now IPv6
support is configured automatically.
*) Change: now if there are no available servers in an upstream, nginx
will not reset number of failures of all servers as it previously
did, but will wait for fail_timeout to expire.
*) Feature: the ngx_stream_ssl_preread_module.
*) Feature: the "server" directive in the "upstream" context supports
the "max_conns" parameter.
*) Feature: the --with-compat configure option.
*) Feature: "manager_files", "manager_threshold", and "manager_sleep"
parameters of the "proxy_cache_path", "fastcgi_cache_path",
"scgi_cache_path", and "uwsgi_cache_path" directives.
*) Bugfix: flags passed by the --with-ld-opt configure option were not
used while building perl module.
*) Bugfix: in the "add_after_body" directive when used with the
"sub_filter" directive.
*) Bugfix: in the $realip_remote_addr variable.
*) Bugfix: the "dav_access", "proxy_store_access",
"fastcgi_store_access", "scgi_store_access", and "uwsgi_store_access"
directives ignored permissions specified for user.
*) Bugfix: unix domain listen sockets might not be inherited during
binary upgrade on Linux.

character in the HTTP method.
