Public component updates

The following table lists components provided by AWS that include new and updated features.

Important

When you deploy a component, AWS IoT Greengrass installs the latest supported versions of all of that component's dependencies. Because of this, new patch versions of AWS-provided public components might be automatically deployed to your core devices if you add new devices to a thing group, or you update the deployment that targets those devices. Some automatic updates, such as a nucleus update, can cause your devices to restart unexpectedly.

To prevent unintended updates for a component that is running on your device, we recommend that you directly include your preferred version of that component when you create a deployment. For more information about update behavior for AWS IoT Greengrass Core software, see Update the AWS IoT Greengrass Core software (OTA).
