# What's new in Sigma

> Sigma release notes for Apr 18, 2025: New options for the Update member endpoint, require all email exports to run as recipient, and more.

## API

### New options for the Update member endpoint

The [Update member](/reference/update-member) (`PATCH /v2/members/{memberId}`) endpoint includes two new options to better manage scheduled exports when deactivating a user:

* Set `archiveDocuments` to true to archive all documents associated with a user that you deactivate, including scheduled exports associated with those documents.
* Set `archiveScheduledExports` to true to archive only the scheduled exports associated with the documents owned by the deactivated user.

## Admin

### Require all email exports to run as recipient

Sigma admins can now choose to require all email exports to run queries as recipients. After enabling this setting, all new and modified email export schedules run queries as the recipients. For more details, see [Manage export frequency and authentication settings](https://help.sigmacomputing.com/docs/restrict-export-recipients).

## Data modeling

### Materialization support for version-tagged data models

You can now schedule materialization for each tagged version of a data model. For more details, see [Schedule materialization for a version-tagged data model](https://help.sigmacomputing.com/docs/schedule-materialization-for-a-version-tagged-data-model).

## Workbook features

### Customize element styles in a workbook layout

Customize the styling of data elements such as tables, input tables, visualizations, and UI elements. Add or remove padding, change the corner style, add a border, and change the text alignment for text elements.

Set default styles in an organization theme, customize styles for an entire workbook in the workbook settings, or style individual elements.

See [Customize element background and styles](https://help.sigmacomputing.com/docs/customize-element-background-and-styles) and [Workbook settings overview](https://help.sigmacomputing.com/docs/workbook-settings-overview).

### Format Slack messages in exports

Add formatting to Slack messages, such as hyperlinks and text formatting. See [Export to Slack](https://help.sigmacomputing.com/docs/export-to-slack) for more details.

## Bug fix

* When exporting grouped tables with totals, the totals now appear in a separate column with a correct header, for example, *Column Name (Grand Total)*.
