 ### Features
 
 * (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.
+* (apps/27-interchain-accounts) [\#2193](https://github.com/cosmos/ibc-go/pull/2193) Adding `InterchainAccount` gRPC query endpont to ICS27 `controller` submodule to allow users to retrieve registered interchain account addresses.
