+# Device Update for IoT Hub release notes
+
+Device Update for IoT Hub is an Azure service designed to work with an on-device agent built from the open-source Device Update for IoT Hub project hosted on GitHub. All new agent releases are made available under the [Releases section](https://github.com/Azure/iot-hub-device-update/releases) of the Github repository. Contributions, feature requests, and bug reports can also be filed on the [open-source Device Update for IoT Hub repository](https://github.com/Azure/iot-hub-device-update).
+
+## Detailed changelog for "February 2023 UX Release"
+
+This latest UX release, titled "February 2023 UX Release," consists of several improvements to the Azure Portal UX. These improvements are compatible with the [GA launch API version](https://learn.microsoft.com/en-us/rest/api/deviceupdate/2022-10-01/device-update) and agent versions [v1.0.0](https://github.com/Azure/iot-hub-device-update/releases/tag/1.0.0), [v1.0.1](https://github.com/Azure/iot-hub-device-update/releases/tag/1.0.1), and [v1.0.2](https://github.com/Azure/iot-hub-device-update/releases/tag/1.0.2).
+
+### Improvements
+
+* Simplified the **Updates** tab by removing the dedicated tab for import history. Import history can still be accessed by clicking **View import history**.
+* Added the **Manage Device Update limits** section to the **Diagnostics** tab. This section details how close your instance is to hitting [Device Group and Device Class limits](https://learn.microsoft.com/en-us/azure/iot-hub-device-update/device-update-limits).
+* Added the ability to export Deployment details to a CSV or Excel file. This can be done by navigating to the **Deployment history** tab within a Device Group and selecting **View deployment details** then clicking **Export to CSV**.
+* Added the ability to navigate directly to **Deployment details** after creating a new deployment from the **Available updates** blade.
+* Added a guided tutorial which walks through creation of an import manifest if one is not included when importing a new update. This **Create manifest** tutorial can be accessed by starting a new import and selecting the desired update files from your storage container. If you do not include an import manifest (file with .importmanifest.json extension), the resulting error message contains a hyperlink ("create one") that opens the Import tutorial.
+* Added a hyperlink to the storage container where log files from a successful log operation have been uploaded. This can be accessed by navigating to the **Log upload operation details** blade and opening the **Devices** section. Each device that successfully completed the log upload operation should display a hyperlink ("Open storage container") in the **Log location** field.
