+    The attribute set defintion files may no longer contain
+    redirection to other fields. 
+    For example the following snippet of
+    a custom <filename>custom/bib1.att</filename> 
+    <literal>Bib-1</literal> attribute set definition file is no
+    longer supported:
+    <screen>

+    </screen>
+    and should be changed to 
+    <screen>
+     att 1016            Any
+    </screen>

+    a new index <literal>Any:w</literal> in all GRS
+    <filename>*.abs</filename> record indexing configuration files.
