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.
