+-----------------------------
+
+  The API is changed.
+
+  The way that presentational hints are handled has changed to be more
+  optimal.  Instead of calling the presentational hint callback once
+  per property per node to get each hint, we now call the callback once
+  per node to get all the hints that apply to it.
+
+  There are changes to selection handler callback table:
+
+    node_presentational_hint
+      Rather than asking for any hint for the given node and property,
+      it now asks for an array of hints that should apply to the node.
+
+  The css_hint structure has been changed to include the property which
+  the hint applies to.
