<p>Added the <br-option>log-level-stderr</br-option> option to control whether console log messages are sent to <id>stderr</id> or <id>stdout</id>. By default this is set to <setting>warn</setting> which represents a change in behavior from previous versions, even though it may be more intuitive. Setting <br-option>log-level-stderr=off</br-option> will preserve the old behavior.</p>
