    *) Feature: the "break" directive.

    *) Feature: the "log_not_found" directive.

    *) Bugfix: the response status code was not changed when request was
       redirected by the ""X-Accel-Redirect" header line.

    *) Bugfix: the variables set by the "set" directive could not be used
       in SSI.

       than one remote subrequest.
