# What's new in Sigma

> Sigma release notes for May 24, 2024: SUPPORT CHATS audit log dimension table, nodeType property for JavaScript embed event, and more.

## Admin

### SUPPORT_CHATS audit log dimension table

Reference information about user interactions with Sigma's live chat support feature.

The **SIGMA_SHARED** schema in the **Sigma Audit Logs** connection now features a **SUPPORT_CHATS** dimension table containing information about individual live chat conversations, including timestamp, user name, user email, and the full chat transcript.

## Embeds

### nodeType property for  `workbook:selectednodeid:update`

Determine whether a selected node is a page or an element by referencing the `nodeType` property in the `workbook:selectednodeid:update` inbound event.

For more information, see [Available inbound events](https://help.sigmacomputing.com/docs/inbound-and-outbound-events-in-embeds#workbookselectednodeidupdate).

## Workbook elements

### Data labels in maps

Add one or more columns to generate data labels in point and region maps. This update makes it easier to quickly view at-a-glance details directly in the element.

For more information, see [Display chart data labels](https://help.sigmacomputing.com/docs/display-chart-data-labels).

### Custom formula aggregations in chart reference marks

Specify a custom formula aggregation when configuring reference marks in charts.

For more information about reference marks, see [Display chart reference marks](https://help.sigmacomputing.com/docs/display-chart-reference-marks).

### Donut hole value in donut charts

Display an aggregate value within the hole of a donut chart to add more context to your visualization.

For details about adding a donut hole value, see [Pie and donut charts](https://help.sigmacomputing.com/docs/pie-and-donut-charts).

## Workbook features

### Custom SQL editor (Beta)

Use the new SQL editor—featuring a more integrated and collaborative experience—to build workbooks, datasets, and elements (tables, pivot tables, and visualizations) with custom SQL.

The Beta release includes the following enhanced capabilities:

* Toggle to an inline SQL editor view within any SQL-based workbook element, and expand the element to enter full screen mode.
* Collaborate with other workbook developers in a live editing environment.
* Use search and replace functionality within the custom SQL.
* Apply autocomplete suggestions featuring improved performance.
* View and access custom SQL from the workbook **Lineage** view.

For more information about using custom SQL directly in Sigma, see [Write custom SQL](https://help.sigmacomputing.com/docs/write-custom-sql).

## Bug fixes

* In the **Administration** > **Embeds** page, you can now successfully preview an embed in the **Embed Sandbox** when you click **More** and select **Test embed**.
* When viewing an individual embed user's profile in the **Administration** > **People** page, the **Edit member and account type** modal now displays "Embed user" in the **Account type** field instead of "Invalid selection."
