Update your IoT Edge devices on Raspberry Pi OS Stretch
Published date: May 06, 2022
Because community support for Debian 9 (Stretch) LTS will end June 30, 2022, we will no longer release patch updates for IoT Edge on Raspberry Pi OS Stretch devices. Your IoT Edge device will continue to run and your applications will not be impacted. Previously published packges for Stretch will continue to be available. However, after that date we will no longer be publishing patch releases of IoT Edge's armhf packages targeting Stretch.
Recommended action: To avoid potential security vulnerabilities update your host OS to Bullseye using the arm32v7 packages now available on packages.microsoft.com.
