# What's new in Sigma

> Sigma release notes for Oct 25, 2024: Improved data source selection UI in embeds, restore a workbook to a previous change, and more.

## Embeds

### Improved data source selection UI in embeds

Select data sources for workbook elements using a new popover UI. With the new experience, you can search for data sources, review a list of suggested sources, and preview data sources. Preview a data source to review the source data and choose specific columns to apply to the element.

For more information, see [Create a data element](https://help.sigmacomputing.com/docs/create-a-data-element).

## Workbook features

### Restore a workbook to a previous change

You can now restore a workbook to a previous change in the edit history for a draft or previously published version.

For more details, see [Workbook versions and version history](https://help.sigmacomputing.com/docs/workbook-versions-and-version-history).

## Bug fixes

* Swapping data sources when promoting a workbook from one tag to another tag now works as expected.
* When creating a dynamic title, the type ahead suggestions in the formula bar in the overlay now include the available table columns as well as controls.
* When responsive height is enabled in an embedded object, opening a modal in the embedded content now displays the modal at the current scroll position.
