Changes with nginx 0.7.40 09 Mar 2009v0.7.40

    *) Feature: the "location" directive supports captures in regular
       expressions.

    *) Feature: an "alias" directive with capture references may be used
       inside a location given by a regular expression with captures.

    *) Feature: the "server_name" directive supports captures in regular
       expressions.

    *) Workaround: the ngx_http_autoindex_module did not show the trailing
       slash in directories on XFS filesystem; the issue had appeared in
       0.7.15.
       Thanks to Dmitry Kuzmenko.
