nginx 0.6.6 *) Feature: the --sysconfdir=PATH option in configure. *) Feature: named locations. *) Feature: the $args variable can be set with the "set" directive. *) Feature: the $is_args variable. *) Bugfix: fair big weight upstream balancer. *) Bugfix: if a client has closed connection to mail proxy then nginx might not close connection to backend. *) Bugfix: if the same host without specified port was used as backend for HTTP and HTTPS, then nginx used only one port - 80 or 443. *) Bugfix: fix building on Solaris/amd64 by Sun Studio 11 and early versions; bug appeared in 0.6.4.
