# What's new in Sigma

> Sigma release notes for Jan 12, 2024: Column-level security, and more.

## Admin

### Column-level security (GA)

Column-level security is now generally available.

The feature provides admins with the flexibility to restrict or grant access to column-level data. This granular control over data access allows your organization to secure sensitive or confidential information, ensuring it's accessible to authorized users only.

For more information, see [Column-level security](https://help.sigmacomputing.com/docs/column-level-security).

## Bug fix

* Sigma successfully exports a tagged workbook version when recipients have access to the tagged version. The export no longer relies on recipients' access to the source workbook.
