## Admin

### New audit log dimension tables (Beta)

The **SIGMA_SHARED** schema in the **Sigma Audit Logs** connection now features the following dimension tables containing information about your organization:

|                       |                                       |
| :-------------------- | :------------------------------------ |
| **TEAM_MEMBERS**      | Organization team member attributes.  |
| **DOCUMENT_ELEMENTS** | Workbook element and page attributes. |

Dimension tables can be joined with the **AUDIT_LOGS** table to add context to audit log events.

## Workbook elements

### Data label improvements in pie and donut charts

Data label responsiveness and positioning have been updated in pie and donut charts to prevent overlap and improve overall readability.

## Workbook features

### CSV upload on Azure and AWS-EU

CSV upload is now available to Sigma organizations hosted on Microsoft Azure and Amazon Web Services Europe (AWS-EU). For more information, see [Upload CSVs](https://help.sigmacomputing.com/docs/upload-csvs).

## Bug fixes

* Resolved an issue that prevented users from deleting hidden pages in workbooks.
* The embed menu now updates the workbook owner when ownership is re-assigned.
