 ### API Breaking
 
+* (modules/core) [\#161](https://github.com/cosmos/ibc-go/pull/161) Remove Type(), Route(), GetSignBytes() from 02-client, 03-connection, and 04-channel messages.
 * (modules) [\#140](https://github.com/cosmos/ibc-go/pull/140) IsFrozen() client state interface changed to Status(). gRPC `ClientStatus` route added.
 * (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.
