 == Venues ==
 
+In the web interface, we need to continue supporting venues.
+In addition to Home/Work/School, we should let users specify
+their own venue names.
+
 == Backwards compatibility ==
+
+The prefs schema proposed here is not compatible
+with old-style prefs.
+We need to think about the following cases:
+
+ * old client gets new-style prefs from a project
+ * new client gets old-style prefs from a project
+ * project with new server code gets old-style prefs from a client
+ * project with old server code gets new-style prefs from a client
+
+The best approach I can think of is:
+
+ * new prefs are stored in new XML elements
+ * when new prefs are converted to XML,
+ we generate old-style XML to the extent possible
+ * the new client can parse both old- and new-style XML.
+ If new-style is there, it ignore the old style.
