Changes with nginx 0.7.1 26 May 2008

    *) Change: now locations are searched in a tree.

    *) Change: the "optimize_server_names" directive was canceled due to
       the "server_name_in_redirect" directive introduction.

    *) Change: some long deprecated directives are not supported anymore.

    *) Change: the "none" parameter in the "ssl_session_cache" directive;
       now this is default parameter.
       Thanks to Rob Mueller.

    *) Bugfix: worker processes might not catch reconfiguration and log
       rotation signals.

    *) Bugfix: nginx could not be built on latest Fedora 9 Linux.
       Thanks to Roxis.
