# What's new in Sigma

> Sigma release notes for Oct 17, 2025: IP Allowlist for UI/Application, Dutch now supported as a workbook locale, and more.

## Admin

### IP Allowlist for UI/Application (GA)

You can configure an IP allowlist for the Sigma UI. After enabling the allowlist, you can add individual IP addresses or ranges of addresses in CIDR notation. Only users in the allowlist are able to access the Sigma application through the user interface. For more information, see [Restrict access to Sigma by IP](https://help.sigmacomputing.com/docs/restrict-access-to-sigma-by-ip-address).

Previously, the IP allowlist applied only to the API. Existing IP allowlists for the API have been preserved with a Scope of API.

### Dutch now supported as a workbook locale

You can now set Dutch (nl-nl) as your workbook locale. Apply the Dutch language, date format, and currency can to workbook previews and embedded workbooks.

See [Manage workbook localization](https://help.sigmacomputing.com/docs/manage-workbook-localization).

### Audit log support for AWS UK region

Sigma now supports audit log events for organizations hosted in the AWS UK region.

## Data apps

### Single-select columns in input tables (Beta)

Add a single-select column to an input table to allow users to select one value per row from a predefined list of values (text, number, or date). You can manually create and manage a list of distinct and repeatable values, or you can populate the list from an existing data source or element in the workbook. Values can then be formatted as pills and assigned different colors for visual differentiation and clarity.
For more information, see [Configure single-select or multi-select columns on input tables](https://help.sigmacomputing.com/docs/configure-single-select-and-multi-select-columns-on-input-tables).

## Functions and calculations

### ArrayConcat function

You can use the ArrayConcat function to combine multiple arrays, maintaining all items and their order. For more information, see [ArrayConcat](https://help.sigmacomputing.com/docs/arrayconcat).

## Workbook features

### Option to unshare a shared view of a workbook

In the **Saved views** panel, you can quickly change a shared view to a personal view to remove visibility for other users with access to the workbook. Click **More** next to the name of a shared view, then select **Set as personal view** to make it only visible to you.

### Copy and paste multiple elements at once

You can now copy and paste more than one element at a time in a workbook or data model. See [Copy and paste workbook elements](https://help.sigmacomputing.com/docs/copy-and-paste-elements#/).

## Bug fixes

* When an action with an **On select** trigger is configured on a bar chart, selecting an axis label of an unaggregated value no longer generates column rank instead of the defined value.
* When a **Set control value** action is triggered by selecting any column in a table, pivot table, or input table, pressing the up arrow key to select the column header (consequently selecting the entire column) no longer clears the control value.
* The list of database or catalog objects visible when browsing a connection in Sigma can now be expanded to view more information without hovering, such as long table names.
* Sigma now correctly displays the selected state for a workbook page based on the selected **Customize page visibility** setting.
