Release highlights
-
Offline authentication – Amazon IoT Greengrass now supports offline authentication. You can configure your Amazon IoT Greengrass core device so that client devices can connect to a core device, even when the core device isn't connected to the cloud. For more information, see Offline authentication.
-
Subdeployments – You can now create subdeployments. You can use a subdeployment to resolve unsuccessful deployments. Each subdeployment can test a different configuration of an unsuccessful deployment on a smaller subset of devices. For more information, see Create subdeployments.
Release details
Public component updates
The following table lists Amazon-provided components that include new and updated features.
When you deploy a component, Amazon IoT Greengrass installs the latest supported versions of all of that component's dependencies. Because of this, new patch versions of Amazon-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 Amazon IoT Greengrass Core software, see Update the Amazon IoT Greengrass Core software (OTA).
