Vertex AI extensions You can create Vertex AI extensions for the APIs registered in API hub

## Feature **Vertex AI extensions** You can create [Vertex AI](https://cloud.google.com/vertex-ai/generative-ai/docs/extensions/overview) extensions for the APIs registered in API hub. These extensions can be integrated with Large Language Models (LLMs) to process real-time data. For more information, see [Create a Vertex AI extension](https://cloud.google.com/apigee/docs/apihub/vertex-extensions#createextension). ## Feature **Eventarc triggers** API hub is integrated with Google Cloud's [Eventarc](https://cloud.google.com/eventarc/docs). You can now create Eventarc triggers to listen for specific events in API hub, and then trigger custom workflows based on the event. For more information, see [Create an Eventarc trigger](https://cloud.google.com/apigee/docs/apihub/quickstart-create-event-triggers). ## Feature **Multi-level delete** By default, you can delete an API only if all underlying versions are deleted. Starting with this release, you can use the _force_ option to delete an API and its child resources in a single step. For more information, see [Delete an API resource](https://cloud.google.com/apigee/docs/apihub/manage-apis#deleteapi).
