Changes with nginx 1.5.5                                         17 Sep 2013

*) Change: now nginx assumes HTTP/1.0 by default if it is not able to
detect protocol reliably.

*) Feature: the "disable_symlinks" directive now uses O_PATH on Linux.

*) Feature: now nginx uses EPOLLRDHUP events to detect premature
connection close by clients if the "epoll" method is used.

*) Bugfix: in the "valid_referers" directive if the "server_names"
parameter was used.

*) Bugfix: the $request_time variable did not work in nginx/Windows.

*) Bugfix: in the "image_filter" directive.
Thanks to Lanshun Zhou.

*) Bugfix: OpenSSL 1.0.1f compatibility.
Thanks to Piotr Sikora.
