 ===================
 
+New Features
+------------
+
+- ZODB no-longer depends on zope.event.  It now uses ZODB.event, which
+  uses zope.event if it is installed. You can override
+  ZODB.event.notify to provide your own event handling, although
+  zope.event is recommended.

 Now, we'll restart the server.  Before we do that, we'll capture

 Note that the event handler is saving away the length of the cache and
 the state of the log handler.  We'll use this to show that the event
 is generated before the cache is dropped or the message is logged.
