+  o Minor bugfixes (TLS protocol, integration tests):
+    - When classifying a client's selection of TLS ciphers, if the client
+      ciphers are not yet available, do not cache the result. Previously,
+      we had cached the unavailability of the cipher list and never looked
+      again, which in turn led us to assume that the client only supported
+      the ancient V1 link protocol.  This, in turn, was causing Stem
+      integration tests to stall in some cases.
+      Fixes bug 30021; bugfix on 0.2.4.8-alpha.
