# What's new in Sigma

> Sigma release notes for Aug 30, 2024: New option for Swap workbook datasources endpoint, new query parameter for List workbooks endpoint, and more.

## API

### New option for **Swap workbook datasources** endpoint

The [Swap workbook datasources](/reference/source-swap-workbook)  endpoint (`POST /v2/workbooks/{workbookId}/swapSources`) now includes the `swapTables` and `paths` options.

* Set the `swapTables` option to true in your request to change all tables in the workbook to use the new connection.
* Use the `paths` option to specify connection paths to map from the original connection to the new connection. For example, to swap a workbook connection from `DB1.ExampleSchema` to `DB2.SampleSchema`, use this option.

### New query parameter for **List workbooks** endpoint

The [List workbooks](/reference/list-workbooks) endpoint (`GET /v2/workbooks`) now includes the `excludeTags` query parameter. Set `excludeTags` to `true` to improve query performance in cases where you do not need version tag information in the response.

## Workbook features

### New option for **Export to email** workbook action

By default, the **Export to email** workbook action now runs as the user who performs the action instead of as the recipient of the email. You can optionally select to run as recipient instead.

See [Create actions that download and export data](https://help.sigmacomputing.com/docs/create-actions-that-download-and-export-data#export-to-email)  for more details.
