+  o Minor bugfixes:
+
+    - If we can't attach streams to a rendezvous circuit when we
+      finish connecting to a hidden service, clear the rendezvous
+      circuit's stream-isolation state and try to attach streams
+      again.  Previously, we cleared rendezvous circuits' isolation
+      state either too early (if they were freshly built) or not at
+      all (if they had been built earlier and were cannibalized).
+      Bugfix on 0.2.3.3-alpha; fixes bug 4655.
