As a best practice, we recommend that you use the latest version of IDT for FreeRTOS that supports your target version of FreeRTOS. Each version of IDT for FreeRTOS has one or more corresponding versions of FreeRTOS that it supports. We recommend that you download a new version of IDT for FreeRTOS when a new version of FreeRTOS is released.

**Important**  
As of October 2022, Amazon IoT Device Tester for Amazon IoT FreeRTOS Qualification (FRQ) 1.0 doesn't generate signed qualification reports. You can't qualify new Amazon IoT FreeRTOS devices to list in the [Amazon Partner Device Catalog](https://partners.amazonaws.com/qualified-devices) through the [Amazon Device Qualification Program](http://aws.amazon.com/partners/programs/dqp/) using IDT FRQ 1.0 versions. While you can't qualify FreeRTOS devices using IDT FRQ 1.0, you can continue to test your FreeRTOS devices with FRQ 1.0. We recommend that you use [IDT FRQ 2.0](https://docs.amazonaws.cn/freertos/latest/userguide/lts-idt-freertos-qualification.html) to qualify and list FreeRTOS devices in the [Amazon Partner Device Catalog](https://partners.amazonaws.com/qualified-devices).
