 CHANGES
 =======
 
-3.14.1 (unreleased)
+3.15.0 (2012-01-19)
 -------------------
 
-- Nothing to release yet.
+- Fixed: zope.app.wsgi.paste.ZopeApplication didn't emit
+  ProcessStarting events.
 
+  **NOTE**
+    If an application compensated for this by generating the event, it
+    will need to stop or there will be multiple events
+    emited. (Whether or not multiple events will do any harm is
+    application specific.)
