+        <para> Previously, Shorewall has treated traffic shaping class IDs as

+        IPMARK was implemented. IPMARK requires Shorewall to generate class
+        Ids in numeric sequence. In 4.3.9, that didn't work correctly because
+        Shorewall was generating the sequence "..8,9,10,11..." when the
+        correct sequence was "...8,9,a,b,...". Shorewall now treats class IDs
