nginx-0.1.36-RELEASE import
*) Change: if the request header has duplicate the "Host",
"Connection", "Content-Length", or "Authorization" lines, then nginx
now returns the 400 error.
*) Change: the "post_accept_timeout" directive was canceled.
*) Feature: the "default", "af=", "bl=", "deferred", and "bind"
parameters of the "listen" directive.
*) Feature: the FreeBSD accept filters support.
*) Feature: the Linux TCP_DEFER_ACCEPT support.
*) Bugfix: the ngx_http_autoindex_module did not support the file names
in UTF-8.
*) Bugfix: the new log file can be rotated by the -USR1 signal only if
the reconfiguration by the -HUP signal was made twice.
