nginx 0.7.18
*) Change: the "underscores_in_headers" directive; now nginx does not
allows underscores in a client request header line names.
*) Feature: the ngx_http_secure_link_module.
*) Feature: the "real_ip_header" directive supports any header.
*) Feature: the "log_subrequest" directive.
*) Feature: the $realpath_root variable.
*) Feature: the "http_502" and "http_504" parameters of the
"proxy_next_upstream" directive.
*) Bugfix: the "http_503" parameter of the "proxy_next_upstream" or
"fastcgi_next_upstream" directives did not work.
*) Bugfix: nginx might send a "Transfer-Encoding: chunked" heaer line
for HEAD requests.
*) Bugfix: now accept threshold depends on worker_connections.
