nginx 1.3.9 *) Feature: support for chunked transfer encoding while reading client request body. *) Feature: the $request_time and $msec variables can now be used not only in the "log_format" directive. *) Bugfix: cache manager and cache loader processes might not be able to start if more than 512 listen sockets were used. *) Bugfix: in the ngx_http_dav_module.
