# What's new in Sigma

> Sigma release notes for May 31, 2024: OAuth write access, inbound event for bookmark update in embeds, and more.

## Admin

### OAuth write access (Beta)

Configure an OAuth connection with write access to leverage the benefits of OAuth permission management with Sigma's write-access features, including input tables, warehouse views, workbook materializations, and CSV uploads.

For more information, see [Configure OAuth with write access](https://help.sigmacomputing.com/docs/configure-oauth-with-write-access).

## Embeds

### Inbound event for bookmark update in embeds

Use the `workbook:bookmark:update` inbound event to communicate and interact between embedded content and the host application.

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

## Workbook features

### Default version tags

Users with Can edit workbook permission can now designate a tag as the default tag for a workbook. As a result, any user who does not have access to the Published workbook will see the default tagged version. Applying default tags to workbooks with multiple tags results in a more consistent viewing experience.

For more information, see [Set a default tag for a workbook](https://help.sigmacomputing.com/docs/version-tagging#set-a-default-tag-for-a-workboo).

## Bug fixes

* A user's Sigma access token now expires when the OAuth access token expires, ensuring the user is logged out when the OAuth session has ended.
* Updates to filters and sorting in tagged workbook versions are now reflected in exports and no longer trigger errors.
