# What's new in Sigma

> Sigma release notes for Apr 24, 2026: AWS signature V4 authentication for API connectors, advanced governance settings for API connectors, and more.

## Admin

### AWS signature V4 authentication for API connectors

API connectors now support the AWS signature V4 authentication method.

For more information, see [Configure API credentials and connectors in Sigma](https://help.sigmacomputing.com/docs/configure-api-credentials-and-connectors-in-sigma#add-a-new-api-credential-to-sigma).

### Advanced governance settings for API connectors

You can configure advanced settings for API connectors to manage rate limits, redirect rules, and retries.

For more information, see [Configure API credentials and connectors in Sigma](https://help.sigmacomputing.com/docs/configure-api-credentials-and-connectors-in-sigma#configure-governance-settings-for-an-api-connector).

### Copy input table data to tenant organizations (Beta)

When deploying documents to tenant organizations, you can now choose to include the data from input tables in the deployed document.

For details, see [Deploy content to tenant organizations](https://help.sigmacomputing.com/docs/deploy-content-to-tenant-organizations).

### Input table audit history (GA)

Input table audit history is now generally available.

Input table audit history records versioned snapshots of input table row and schema changes over time. For each input table, Sigma automatically creates a warehouse-native view in your data platform that can help you understand the following:

* Row-level history: What changed in a specific row, who made the change, and when the change occurred.
* Schema history: When a column was created or changed to a different data type, along with who made the change and when the change occurred.

For information, see [View input table audit history](https://help.sigmacomputing.com/docs/view-input-table-audit-history).

### Set variables on a Snowflake connection (Beta)

You can now specify [session variables](https://docs.snowflake.com/en/sql-reference/session-variables) on a Sigma connection to Snowflake. After being set up, the session variables are set for each query that Sigma runs in Snowflake.

For more details, including an example implementation, see [Specify session variables for a Snowflake connection](https://help.sigmacomputing.com/docs/specify-session-variables-for-a-snowflake-connection).

## Workbook elements

### Change legend position in map elements

You can now choose the location of the legend on a map. Navigate to **Format** > **Legend** and, next to **Position**, choose an option from the dropdown.

## Bug fixes

* When validating content in a data model or migrating a dataset to a data model with **Update references** selected, downstream documents no longer fail to update due to a permission error.

* Workbooks no longer fail to load when a column exists across multiple properties in an element.
