 ### Features
 
+* [\#11430](https://github.com/cosmos/cosmos-sdk/pull/11430) Introduce a new `grpc-only` flag, such that when enabled, will start the node in a query-only mode. Note, gRPC MUST be enabled with this flag.
 * (x/bank) [\#11417](https://github.com/cosmos/cosmos-sdk/pull/11417) Introduce a new `SpendableBalances` gRPC query that retrieves an account's total (paginated) spendable balances.
 * (x/bank) [\#10771](https://github.com/cosmos/cosmos-sdk/pull/10771) Add safety check on bank module perms to allow module-specific mint restrictions (e.g. only minting a certain denom).
 * (x/bank) [\#10771](https://github.com/cosmos/cosmos-sdk/pull/10771) Add `bank.BankKeeper.WithMintCoinsRestriction` function to restrict use of bank `MintCoins` usage. This function is not on the bank `Keeper` interface, so it's not API-breaking, but only additive on the keeper implementation.
