# What's new in Sigma

> Sigma release notes for Feb 21, 2025: Use connection-level OAuth configurations, and more.

## Admin

### Use different OAuth configurations for authenticating users to your connections than you use for your Sigma organization (Beta)

Sigma now supports authenticating a connection with OAuth without re-using OAuth credentials used for authenticating users to your Sigma organization. As a result:

* You no longer need to use OAuth as your authentication method for your Sigma organization in order to authenticate a connection with OAuth.
* If you use multiple IdPs and data platforms, you can create connections with different OAuth configurations as needed.
* When authenticating Snowflake connections with OAuth, you can configure Proof Key for Code Exchange (PKCE) and/or JSON Web Tokens (JWTs) to secure your connection.

For more information about OAuth, see [Configure OAuth](https://help.sigmacomputing.com/docs/configure-oauth#use-different-oauth-configurations-for-authenticating-users-to-your-connections-than-you-use-for-your-sigma-organization-beta).

For instructions on how to configure a unique OAuth connection for a Databricks or Snowflake connection, see:

* [Connect to Snowflake](https://help.sigmacomputing.com/docs/connect-to-snowflake#connect-to-snowflake-with-oauth)

## Workbook features

### Modal element (GA)

Modals help simplify workbook design and allow you to build a streamlined, app-like experience. An open modal overlays and obscures a workbook page to provide a focused view of the modal content. This reduces visual clutter and allows you to present form fields, provide customized drilldowns, display controls and filters in a dedicated container, etc.

To incorporate a modal into a workbook, you must configure an **Open modal** action. For more information, see [Add a modal to a workbook](https://help.sigmacomputing.com/docs/add-a-modal-to-a-workbook) and [Open or close a modal](https://help.sigmacomputing.com/docs/create-actions-that-navigate-to-destinations#open-or-close-a-modal).
