+  o Security Features:
+    - Provide controllers with a safer way to implement the cookie
+      authentication mechanism. With the old method, if another locally
+      running program could convince a controller that it was the Tor
+      process, then that program could trick the contoller into
+      telling it the contents of an arbitrary 32-byte file. The new
+      "SAFECOOKIE" authentication method uses a challenge-response
+      approach to prevent this. Fixes bug 5185, implements proposal 193.
