+* [\#384](https://github.com/cosmos/ibc-go/pull/384) Added `NegotiateAppVersion` method to `IBCModule` interface supported by a gRPC query service in `05-port`. This provides routing of requests to the desired application module callback, which in turn performs application version negotiation.

This allows for raw binary (proto-encoded message) to be sent over events and decoded correctly on relayer. Original `packet_ack` is DEPRECATED. All relayers and IBC event consumers are encouraged to switch to `packet_ack_hex` as soon as possible.
 * (modules/light-clients/07-tendermint) [\#125](https://github.com/cosmos/ibc-go/pull/125) Implement efficient iteration of consensus states and pruning of earliest expired consensus state on UpdateClient.
 * (modules/light-clients/07-tendermint) [\#141](https://github.com/cosmos/ibc-go/pull/141) Return early in case there's a duplicate update call to save Gas.
+* (modules/core/ante) [\#235](https://github.com/cosmos/ibc-go/pull/235) Introduces a new IBC Antedecorator that will reject transactions that only contain redundant packet messages (and accompany UpdateClient msgs). This will prevent relayers from wasting fees by submitting messages for packets that have already been processed by previous relayer(s). The Antedecorator is only applied on CheckTx and RecheckTx and is therefore optional for each node.
