# What's new in Sigma

> Sigma release notes for Aug 22, 2025: Disable audit logging, set up Key Pair authentication for OAuth service accounts, and more.

## Admin

### Disable audit logging

You can now disable audit logging in Sigma. This will delete any storage integrations and cancel any scheduled exports. Sigma retains your audit log data for 30 days after disabling.

See: [Enable or disable audit logging](https://help.sigmacomputing.com/docs/enable-audit-logging)

### Set up Key Pair authentication for OAuth service accounts (GA)

You can now set up Key Pair authentication for Snowflake OAuth service accounts. For more information, see [Connect to Snowflake with OAuth](https://help.sigmacomputing.com/docs/connect-to-snowflake#connect-to-snowflake-with-oauth).

## AI

### Gemini and Vertex AI integration (Beta)

You can now configure an external AI integration with Google Gemini, or a warehouse AI integration with BigQuery through Google's Vertex AI API.

See: [Configure warehouse AI model integration](https://help.sigmacomputing.com/docs/configure-warehouse-ai-model-integration) and [Manage external AI integrations](https://help.sigmacomputing.com/docs/manage-external-ai-integrations)

## API

### Custom SQL support for swap workbook data sources endpoint (Beta)

The [Swap workbook data sources](/reference/source-swap-workbook) endpoint (`POST /v2/workbooks/{workbookId}/swapSources`) now supports workbooks that use custom SQL statements, in addition to standard table-based sources.

This enables users to update and maintain workbooks without needing to manually rewrite custom SQL queries.

## Data modeling

### Column-level security in data models with user attributes (Beta)

Set column-level security (CLS) rules in a data model according to the assigned value of a user attribute. Users and team members assigned a user attribute value that matches the value specified in the CLS rule can view the contents of the protected column. Users assigned other user attribute values, or not assigned a user attribute value, cannot view the contents of the protected column.

For more details, see [Configure column-level security in a data model](https://help.sigmacomputing.com/docs/column-level-security#configure-column-level-security-in-a-data-model).

## Embeds

### Secure embed URLs signed with client credentials (Deprecated)

Secure embeds with URLs that are secured with client credentials, formerly known as user-backed embeds, are deprecated as of August 4, 2025 and will reach end of support early next year. Instead, migrate to secure embed URLs signed with JSON Web Token (JWT). For guidance, see [Migrate to JWT-signed secure embed URLs](https://help.sigmacomputing.com/docs/migrate-to-jwt-signed-secure-embed-urls).

For questions and additional details, contact your Customer Success Manager.

## Functions and calculations

### IsEven and IsOdd functions

You can now use the IsEven and IsOdd functions to check whether the integer part of a number is even or odd. See [IsEven](https://help.sigmacomputing.com/docs/iseven) and [IsOdd](https://help.sigmacomputing.com/docs/isodd).

## Workbook features

### Export elements from saved views and version tags from the export modal

When sending ad hoc or scheduled exports, you can now select elements that are unique to saved views or version tags from the export modal (**Share and export** > **Export…**/**Schedule exports…**). When exporting elements that are only on a saved view, and not in the published workbook, you must open the export modal from the saved view.

See [Send or schedule workbook exports](https://help.sigmacomputing.com/docs/send-or-schedule-workbook-exports) for more information.

## Bug fixes

* Time chart axes now align with chart data across all timespans and timezones as expected, with more intuitive tick markings across all organization timezones.
* When writing SQL to query a BigQuery connection, project ID, dataset, and table names, and column names now autocomplete.
* The [Download an exported file endpoint](/reference/download-query) (`GET/v2/query/{queryId}/download`) now no longer fails when downloading a workbook.
* Previously, selecting a text element would arbitrarily resize the element by adding rows. Now, this is less likely to happen.
* The files endpoint no longer only returns workbooks owned by the specified user that are located in the My Documents folder. All workbooks owned by the user, including those located across different workspaces, are now returned.
