+### Sensor update in Azure portal now supports selecting a specific version
+
+When you update the sensor in the Azure portal, you can now choose to update to any of the supported, previous versions (versions other than the latest version). Previously, sensors onboarded to Microsoft Defender for IoT on the Azure portal were automatically updated to the latest version.
+
+You might want to update your sensor to a specific version for various reasons, such as for testing purposes, or to align all sensors to the same version.
