# Cognigy.AI v4.9 adds new Extension capabilities

Authors name: [Sebastian Glock](/content/product-updates/author/sebastian-glock/index.html) August 23, 2021

The newest release of Cognigy.AI, v4.9, comes with an embed code for the Webchat Widget. This allows web developers to easily add a Virtual Agent to any website by simply copy/pasting the sources to a web page. The embed code is readily available on the Endpoint configuration page.

## Other new features & functions include:

### Extension performance
This release uplifts the Extension execution performance massively. We have implemented a new caching concept that will cache Extensions in the local container file system. Extensions will be preferably loaded from this local cache instead of the remote storage location.

### Jump to Flow functionality
This release of Cognigy.AI adds a "Jump to Flow" button in our Endpoint editor. This allows users to quickly access Flows from Endpoints.

### Dynamic Fields in Flow Nodes
This release of Cognigy.AI adds new functionality that allows our customers to use a new dynamic select field as a new field type in their Extensions. The feature can be used to dynamically fetch the content of a select field through e.g. an external API call.

### More improvements:
- Updated RSS feed link in index dashboard and updated hyperlink in “Go to blog” button in the news section.
- Improved the autofocus which allows users to use enter key to go to the next NLU example sentence field.
- Improved Flow Editor by adding a warning which will be displayed when Flows have more than 100 Flow nodes.
- Improved the Intent upload functionality by skipping the import options dialog when the list of Intents is empty.
- Improved our MS Teams channel integration by adding the functionality to display the title of a postback button when clicked.
