# What's new in Sigma

> Sigma release notes for Aug 29, 2025: Ask Sigma Discovery, new API endpoint to list sources of a data model, and more.

## AI

### Ask Sigma Discovery

Now, when you access the **Ask Sigma** page, Ask Sigma automatically compiles expandable data collections based on the highlighted data sources for your organization. For more information, see [Ask Sigma Discovery](https://help.sigmacomputing.com/docs/ask-sigma-discovery).

## API

### New API endpoint to list sources of a data model

The following endpoint to list sources of a data model is now available:

* [List data model sources](/reference/list-data-model-sources) (`GET /v2/dataModels/{dataModelId}/sources`)

### New options for the sync connection by path endpoint

The [Sync a connection by path](/reference/sync-connection-path) (`POST /v2/connections/{connectionId}/sync`) endpoint includes a new `useServiceAccount` query string parameter. When used with a connection that uses OAuth, the new option lets you use the service account credentials, instead of the user credentials associated with the API token, to sync the connection. When used with a connection that doesn't use OAuth, the new option has no effect.

## Data apps

### Dependent action notification for element deletion

When you delete an element that's the target of an action, you're notified of the dependency when confirming the element deletion. In the confirmation modal, you can select the **Delete impacted actions** checkbox to delete the dependent action along with the element. Alternatively, if you don't select the checkbox, the broken action is retained, and you can reconfigure it as needed.

### Success alerts for action sequences

Add a custom success alert that displays after an action sequence runs successfully. The alert appears temporarily at the bottom of the window and can include a static or dynamic message.

For more information, see [Add or edit a success alert](https://help.sigmacomputing.com/docs/create-and-manage-action-sequences#add-or-edit-a-success-alert).

## Infrastructure

### Select organization cloud deployment location when signing up for a free trial

When creating a new Sigma organization as a free trial, you can now select your preferred cloud provider and region during the sign up process.

See [Supported regions, data platforms, and features](https://help.sigmacomputing.com/docs/region-warehouse-and-feature-support).

## Workbook elements

### Stretch to fit sizing option for image elements

You can now select a **Stretch to fit** sizing option for image elements. When selected, images stretch to match the dimensions of the image element on the workbook page.

For more information, see [Image elements](https://help.sigmacomputing.com/docs/image-elements).

## Workbook features

### Change the layout grid density of a container (GA)

You can change the layout grid density of a container or tabbed container. In the **Properties** panel for a container or tabbed container, set the **Layout grid density** setting as either **Low**, **Medium**, or **High**. Containers made from a group of selected elements have a **Medium** density by default if the selected elements cover 12 or fewer columns on the workbook page. If the selected elements cover more than 12 columns, the container defaults to **High** density.

See [Change the layout grid density of a container](https://help.sigmacomputing.com/docs/use-containers-to-organize-workbook-layouts#change-the-layout-grid-density-of-a-container).

### Updated scheduled export limitation

Previously, scheduled exports would be automatically suspended if there were 5 consecutive failures within 5 calendar days, or if there were 10 consecutive export failures. Now, they will only be suspended if there are 10 consecutive export failures.

### Updated UI for unavailable export options

When configuring additional options for exports, options in the export modal that are not applicable based on your export configurations will now be greyed out.

For more information, see [Configure additional options for exports](https://help.sigmacomputing.com/docs/configure-additional-options-for-exports).

## Bug fixes

* The **Data sources** tab of the **Select source** modal now shows options as expected even in smaller viewports.
* Referencing a data element in SQL using `sigma_element()` syntax now correctly handles element titles that contain quotes.
* The [Add workbook schedule](/reference/post-workbook-schedule) endpoint (`POST/v2/workbooks/{workbookId}/schedules`) no longer displays invalid request errors when scheduling an export.
