+  o Minor bugfixes:
+    - Correct the man page to explain that HashedControlPassword and
+      CookieAuthentication can both be set, in which case either method
+      is sufficient to authenticate to Tor. Bugfix on 0.2.0.7-alpha,
+      when we decided to allow these config options to both be set. Issue
+      raised by bug 3898.
