# What's new in Sigma

> Sigma release notes for May 23, 2025: Alerts before OAuth sessions expire, warehouse AI model integration, and more.

## Admin

### Alerts before OAuth sessions expire

Users now see an alert message 20 minutes before their connection-level OAuth session expires, prompting them to re-sign into the connection. For more information on OAuth, see [Configure OAuth](https://help.sigmacomputing.com/docs/configure-oauth).

## AI

### Warehouse AI model integration (Beta)

If your organization is connected to Snowflake or Databricks, you can use warehouse-hosted AI models to power Sigma AI features. For information about selecting your data platform as your organization's AI provider, see [Configure warehouse AI model integration](https://help.sigmacomputing.com/docs/configure-warehouse-ai-model-integration).

## Embeds

### New outbound event emitted for deleted workbooks

When a workbook is successfully deleted from the embed menu, an outbound `workbook:ondelete` event is emitted.

For more details, see [workbook:ondelete](https://help.sigmacomputing.com/docs/inbound-and-outbound-events-in-embeds#workbookondelete).

### New `connection_oauth_tokens` JWT claim

The `connection_oauth_tokens` JWT claim is now available. This is an optional claim that allows you to pass OAuth tokens through JWT-signed URLs for connection-level OAuth. For more information, see [JWT claims in Create an embed API with JSON web tokens](https://help.sigmacomputing.com/docs/create-an-embed-api-with-json-web-tokens#jwt-claims).

## Bug fixes

* Archived connections no longer cause unexpected errors in shared templates.
* Changing organization level authentication from OAuth to another authentication method no longer causes independent OAuth configuration options to disappear in Administration.
* The **More**  menu for tables has been updated to remove a nonfunctional Make owner option.
* When using connection-level OAuth, your email is no longer checked to see if it matches the email used for signing in to Sigma.
* Previously, in Snowflake OAuth connections with service accounts enabled, if the `serviceAccountWarehouse` was not set in Sigma, it would be evaluated as undetermined (resulting in an error). Now, if the warehouse is set by a user attribute, the service account will use the default value of the user attribute.
* When pressing <kbd>Tab</kbd> to navigate between elements in a container, the navigation order matches the position of the elements within the container.
* When a container is selected, pressing <kbd>Tab</kbd> correctly changes selection from the container to the top-left-most element in the container.
* When the top-left-most element in a container is selected, pressing <kbd>Shift</kbd> + <kbd>Tab</kbd> selects the parent container.
* When selecting an element in a workbook to navigate to with the **Navigate in this workbook** action, the list of elements for a page matches the order of the elements on the page.
