       on 0.2.2.1-alpha.
     - Fix two memory leaks in the error case of
       circuit_build_times_parse_state. Bugfix on 0.2.2.2-alpha.
-    - Make it explicit that we can't overflow in
-      connection_ap_handshake_send_resolve. Bugfix on 0.0.7.1.
     - Don't count one-hop circuits when we're estimating how long it
       takes circuits to build on average. Otherwise we'll set our circuit
       build timeout lower than we should. Bugfix on 0.2.2.2-alpha.
