+### Features
+
+* (grpc) [#13485](https://github.com/cosmos/cosmos-sdk/pull/13485) Implement a new gRPC query, `/cosmos/base/node/v1beta1/config`, which provides operator configuration.
+
 ### Improvements
 
 * (auth) [#13460](https://github.com/cosmos/cosmos-sdk/pull/13460) The `q auth address-by-id` CLI command has been renamed to `q auth address-by-acc-num` to be more explicit. However, the old `address-by-id` version is still kept as an alias, for backwards compatibility.

+### gRPC
+
+A new gRPC service, `proto/cosmos/base/node/v1beta1/query.proto`, has been introduced
+which exposes various operator configuration. App developers should be sure to
+register the service with the gRPC-gateway service via
+`nodeservice.RegisterGRPCGatewayRoutes` in their application construction, which
+is typically found in `RegisterAPIRoutes`.
