 > [Standard support for Ubuntu 18.04 LTS ends on May 31st, 2023](https://ubuntu.com/blog/18-04-end-of-standard-support). Beginning June 2023, Ubuntu 18.04 LTS won't be a supported platform. Ubuntu 18.04 LTS Device Update packages are available until Nov 30th, 2023. If you take no action, Ubuntu 18.04 LTS based Device Update devices continue to work but ongoing security patches and bug fixes in the host packages for Ubuntu 18.04 won't be available after Nov 30th, 2023. To continue to receive support and security updates, we recommend that you update your host OS to a supported platform. 
 
 ## Releases and Support

 Device Update for IoT Hub 1.0 is the first major release and will continue to receive security fixes and fixes to regressions.  
 
 Device Update (DU) agents use IoT Plug and Play models to send and receive properties and messages from the DU service. Each DU agent requires specific models to be used. Learn more about how device update uses these models and how they can be extended.  
 
-Newer REST Service API versions supports older agents unless specified. Device Update for IoT Hub portal experience uses the latest APIs and have the same support as the API version.

 > [!NOTE]
 > Users, that have extended from the reference agent and customized the agent, are responsible for ensuring the bug fixes and security fixes are incorporated. You will also need to ensure the agent is built and configured correctly as defined by the service to connect service, perform updates, and manage devices from the IoT hub.

 Device Update for IoT Hub offers optimized update deployment and streamlined operations through integration with [Azure IoT Hub](https://azure.microsoft.com/services/iot-hub/). This integration makes it easy to adopt Device Update on any existing solution. It provides a cloud-hosted solution to connect virtually any device. Device Update supports a broad range of IoT operating systems—including Linux and [Eclipse ThreadX](https://github.com/eclipse-threadx) (real-time operating system)—and is extensible via open source. We're codeveloping Device Update for IoT Hub offerings with our semiconductor partners, including STMicroelectronics, NXP, Renesas, and Microchip. See the [samples](https://github.com/eclipse-threadx/samples/tree/PublicPreview/ADU) of key semiconductors evaluation boards that include the get started guides to learn how to configure, build, and deploy the over-the-air updates to MCU class devices.
