+====================
+
+First (in a long time) separate ZEO release.
+
+Since ZODB 3.10.5:
+
+New Features
+------------
+
+- Storage servers now emit Serving and Closed events so subscribers
+  can discover addresses when dynamic port assignment (bind to port 0)
+  is used. This could, for example, be used to update address
+  information in a ZooKeeper database.
+
+- Client storages have a method, new_addr, that can be used to change
+  the server address(es). This can be used, for example, to update a
+  dynamically determined server address from information in a
+  ZooKeeper database.
