# What's new in Sigma

> Sigma release notes for May 22, 2026: Sigma Public, new API endpoint for setting organization time zone, and more.

## AI Apps

### Sigma Public

[Sigma Public](https://public.sigmacomputing.com/sign-up) is now available as a free-to-use platform where you can create, share, and explore apps built in Sigma. Use sample data or upload your own datasets to build workflows in an embedded Sigma experience. You can also search apps created by other users to get inspiration for your next app in Sigma.

For information about creating and managing a Sigma Public account and building public apps, see the [Sigma Public documentation](https://help.sigmacomputing.com/docs/sigma-public).

## API

### New API endpoint for setting organization time zone

The following endpoint is now available to set the time zone of an organization in Sigma:

* [Update organization settings](/reference/update-organization-settings) (`PATCH /v2/organizations/settings`)

If you use Sigma Tenants, you can use this endpoint to set the time zone for tenant organizations.

## Data modeling

### dbt Core integration (Beta)

Add metadata from the output of a dbt Core run to Sigma to visualize freshness data, monitor data quality, and display table and column descriptions configured in dbt directly in Sigma.

To integrate dbt Core with your organization, use the [Add dbt metadata for a connection](/reference/post-connection-dbt-artifacts) (`POST /v2/connections/{connectionId}/dbtArtifacts`) endpoint to upload the artifacts of your dbt run to Sigma. For more details, see [Configure dbt Core integration](https://help.sigmacomputing.com/docs/manage-dbt-integration#configure-dbt-core-integration-beta).

## Workbook elements

### Hierarchy column actions and control improvements (Beta)

Hierarchy column support has now been expanded:

* You can use hierarchies with actions to create logic and interactivity. See [Use hierarchies with actions](https://help.sigmacomputing.com/docs/hierarchies#use-hierarchies-with-actions).
* When searching for values in a hierarchy control, you can now select up to 1,000 values from the search results.
* You can now see all levels of a hierarchy in your control without selecting them individually with the **Expand all levels** option.

See [Work with hierarchies (Beta)](https://help.sigmacomputing.com/docs/hierarchies) and [Hierarchy](https://help.sigmacomputing.com/docs/intro-to-control-elements#hierarchy-beta) controls.

## Workbook features

### Translate Sigma UI text in workbooks

You can now translate the Sigma user interface (UI) text into other languages while editing, viewing, or customizing workbooks.

To apply a locale to a workbook, use the `:lng` query string parameter in the URL with the syntax `:lng=<your-locale>`. See [Manage workbook localization](https://help.sigmacomputing.com/docs/manage-workbook-localization)  for more details.
