 # Release Notes

+
+There is a bug in the `NetworkServiceElement` when it is responding to a
+`WhoIsRouterToNetwork` the router will respond requests from a directly
+connected, even when those requests were on the same adapter.  For example,
+a router between network 1 and 2 would respond as a router to network 1 for
+requests like "who is router to network 1" from devices on network 1, which
+is an error.
