* (apps/27-interchain-accounts) [\#2147](https://github.com/cosmos/ibc-go/pull/2147) Adding a `SubmitTx` gRPC endpoint for the ICS27 Controller module which allows owners of interchain accounts to submit transactions. This replaces the previously existing need for authentication modules to implement this standard functionality.
* (testing/simapp) [\#2190](https://github.com/cosmos/ibc-go/pull/2190) Adding the new `x/group` cosmos-sdk module to simapp.
* (apps/transfer) [\#2305](https://github.com/cosmos/ibc-go/pull/2305) Added optional metadata field to `FungibleTokenPacketData` and `MsgTransfer`.
* (apps/transfer) [\#2595](https://github.com/cosmos/ibc-go/pull/2595) Adding optional memo field to `FungibleTokenPacketData` and `MsgTransfer`.
