# What's new in Sigma

> Sigma release notes for Dec 8, 2023: JavaScript event for element errors, chart and table element descriptions, and more.

## Embeds

### JavaScript event for element errors

Elements that fail to load in embeds trigger a JavaScript event that includes the element ID, message, and API error code.

## Workbook elements

### Chart and table element descriptions

Add descriptions to chart and table elements and display them as subtitles or tooltips. Go to **Element format** > **Title** and select the **Show description** checkbox to enable and configure the element description.

For more information, see the [Create a dynamic title](https://help.sigmacomputing.com/docs/customize-element-title#create-a-dynamic-title) section in [Customize element title](https://help.sigmacomputing.com/docs/customize-element-title).

### Vertical alignment in text elements

Control the vertical alignment of content in text elements for improved text display. Go to **Element properties** and choose top, center, or bottom alignment.

## Workbook features

### Additional entry point to license upgrade request

When a Viewer-licensed user clicks **Create New** in the side panel, Sigma notifies them that the ability to create workbooks requires an account upgrade. The user can send a request to organization admins, who can then upgrade the user's license by reassigning them to an account type with **Create, edit, and publish workbooks** permission.

## Bug fixes

* Sigma now verifies user account type permissions and only sends version tag email requests to users granted the **Create, edit, and publish workbooks** and **Apply tag** permissions. Viewer-licensed users (who cannot edit workbooks or apply tags) no longer receive the requests.
* Initial clicks on list control elements in embedded workbooks no longer cause the iframe display to jump to the top of the workbook.
