+  - Use `NetworkControllerGetNetworkConfigurationByNetworkClientIdAction` instead.
 - **BREAKING:** Automatically populate `isRpcFailoverEnabled` using `RemoteFeatureFlagController` ([#9013](https://github.com/MetaMask/core/pull/9013))
   - `NetworkController.init` must now be called to fully initialize the controller.
   - The constructor argument `isRpcFailoverEnabled` is no longer available.
