nginx 0.7.1
*) 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.
