+* (modules/core) [\#109](https://github.com/cosmos/ibc-go/pull/109) Remove connection and channel handshake CLI commands.
 * (modules) [\#107](https://github.com/cosmos/ibc-go/pull/107) Modify OnRecvPacket callback to return an acknowledgement which indicates if it is successful or not. Callback state changes are discarded for unsuccessful acknowledgements only. 
 * (modules) [\#108](https://github.com/cosmos/ibc-go/pull/108) All message constructors take the signer as a string to prevent upstream bugs. The `String()` function for an SDK Acc Address relies on external context.
