# Support policy for Amazon IoT Device Tester for Amazon IoT Greengrass V1
<a name="idt-support-policy"></a>

Amazon IoT Device Tester (IDT) for Amazon IoT Greengrass is a downloadable testing framework that lets you validate and [qualify](http://www.amazonaws.cn/partners/dqp/) your Amazon IoT Greengrass devices for inclusion in the [Amazon Partner Device Catalog](https://devices.amazonaws.com/). We recommend that you use the most recent version of Amazon IoT Greengrass and IDT to test or qualify your devices. For more information, see [Supported versions of IDT for Amazon IoT Greengrass V2](https://docs.amazonaws.cn/greengrass/v2/developerguide/dev-test-versions.html) in the *Amazon IoT Greengrass Version 2 Developer Guide*.

You can also use any of the supported versions of Amazon IoT Greengrass and IDT to test or qualify your devices. Although you can continue to use [unsupported versions of IDT](dev-test-versions.md#idt-unsupported-versions), those versions do not receive bug fixes or updates.

**Important**  
As of April 4, 2022, Amazon IoT Device Tester (IDT) for Amazon IoT Greengrass V1 no longer generates signed qualification reports. You can no longer qualify new Amazon IoT Greengrass V1 devices to list in the [Amazon Partner Device Catalog](https://devices.amazonaws.com/) through the [Amazon Device Qualification Program](https://www.amazonaws.cn/partners/programs/dqp/). While you can't qualify Greengrass V1 devices, you can continue to use IDT for Amazon IoT Greengrass V1 to test your Greengrass V1 devices. We recommend that you use [IDT for Amazon IoT Greengrass V2](https://docs.amazonaws.cn/greengrass/v2/developerguide/device-tester-for-greengrass-ug.html) to qualify and list Greengrass devices in the [Amazon Partner Device Catalog](https://devices.amazonaws.com/).
