 **IoT Hub updates**
 
-* [Breaking Change] The `az iot hub device-identity export` and `az iot hub device-identity import` commands are migrated to use dataplane/IoT Hub APIs instead of controlplane/ARM.
-* [Breaking Change] Device identity export/import operations now expect the parameter `auth-type` to specify IoT Hub API auth type (instead of storage auth type).
+* **[Breaking Change]** The `az iot hub device-identity export` and `az iot hub device-identity import` commands have been migrated to use IoT Hub APIs instead of ARM.
+* **[Breaking Change]** Device identity export/import commands now expect the parameter `--auth-type` to specify the IoT Hub API data access auth type (instead of storage access auth type).
 * Updated the IoT Hub service SDK to now use the newer `2021-04-12` API version.
 * Device identity export/import commands now support optional parameters for storage account and blob container names - users no longer need to supply input/output Blob container SAS URIs.
-* Device identity export/import operations now automatically derive storage auth type - hence the parameter `storage_authentication_type` has been deprecated.
+* Device identity export/import commands now automatically derive storage auth type - hence the parameter `storage_authentication_type` has been deprecated.
 * Adds `az iot hub device-twin list` as a highly recommended alternative to `az iot hub device-identity list`.
   Functionality remains the same as both return a list of device twins and `az iot hub device-identity list` may be altered or deprecated in the future.
