+  o Minor features (directory authority):
+    - Authorities now recommend protocol versions that are supported
+      by Tor 0.3.5 and later. (Earlier versions of Tor have been
+      deprecated since January of this year.)  This recommendation
+      will cause older clients and relays to give a warning on startup,
+      or when they download a consensus directory.
+      Closes ticket 32696.
