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.
