+
+I would like to add a piece of advice: Most of the improvements on
+incremental updates are in the new isam system. To see them in effect,
+you will have to add the line
+  isam: b
+in your zebra.cfg. After this you will need to reindex everything. The
+effect should be especially good on smallish incremental updates to
+large bases. 
+
+The isam-b was introduced in 1.3.0, but we recommend using 1.3.2 (or
+later).
