*) Feature: the "so_keepalive" parameter of the "listen" directive.
Thanks to Vsevolod Stakhov.
*) Feature: the "if_not_empty" parameter of the
"fastcgi/scgi/uwsgi_param" directives.
*) Feature: the $https variable.
*) Feature: the "proxy_redirect" directive supports variables in the
first parameter.
*) Feature: the "proxy_redirect" directive supports regular expressions.
*) Bugfix: the $sent_http_cache_control variable might contain a wrong
value if the "expires" directive was used.
Thanks to Yichun Zhang.
*) Bugfix: the "read_ahead" directive might not work combined with
"try_files" and "open_file_cache".
