## Public component updates
<a name="greengrass-2023-06-05-components"></a>

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

**Important**  <a name="component-patch-update-note"></a>
<a name="component-patch-update"></a>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.   
<a name="component-version-pinning"></a>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](create-deployments.md). For more information about update behavior for Amazon IoT Greengrass Core software, see [Update the Amazon IoT Greengrass Core software (OTA)](update-greengrass-core-v2.md).
