 * (grpc) [#13485](https://github.com/cosmos/cosmos-sdk/pull/13485) Implement a new gRPC query, `/cosmos/base/node/v1beta1/config`, which provides operator configuration. Applications that wish to expose operator minimum gas prices via gRPC should have their application implement the `ApplicationQueryService` interface (see `SimApp#RegisterNodeService` as an example).
 * [#13557](https://github.com/cosmos/cosmos-sdk/pull/#13557) - Add `GenSignedMockTx`. This can be used as workaround for #12437 revertion. `v0.46+` contains as well a `GenSignedMockTx` that behaves the same way.
+* (x/auth) [#13612](https://github.com/cosmos/cosmos-sdk/pull/13612) Add `Query/ModuleAccountByName` endpoint for accessing the module account info by module name.
