 * (core/24-host) [\#2820](https://github.com/cosmos/ibc-go/pull/2820) Add `MustParseClientStatePath` which parses the clientID from a client state key path. 
 * (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.
+* (testing/simapp) [\#2842](https://github.com/cosmos/ibc-go/pull/2842) Adding the new upgrade handler for v6 -> v7 to simapp which prunes expired Tendermint consensus states.
