# What's new in Sigma

> Sigma release notes for Aug 15, 2025: Input table audit logging, more options for managing source visibility, and more.

## Admin

### Input table audit logging (Beta)

Audit logs now record events and metadata related to input table activity. Admins can parse input table audit log data to understand the type of edit performed (e.g., create input table, add row, update row, delete row, etc.), who was responsible, and when the activity occurred. The metadata identifies the edited input table as well as the number of affected rows and columns, but it does not record the content of the edits.

For more information about input table audit log events and metadata, see the `INPUT_TABLES` event category in the [Audit events reference tables](https://help.sigmacomputing.com/docs/audit-log-events-and-metadata#audit-events-reference).

## Data modeling

### More options for managing source visibility

You can enable or disable a table as a data source in a data model from the data model overview using **Show as source**, or the toggle on the modeling tab of the editor panel. See [Enable or disable an element as a data source](https://help.sigmacomputing.com/docs/create-and-manage-data-models#enable-or-disable-an-element-as-a-data-source).

## Workbook elements

### Create and format sparklines (Beta)

Sigma now supports creating and formatting sparklines in tables and pivot tables. You can add sparklines from a grouped column in a table (**Add column via… > Sparkline**), or using the [SparklineAgg](https://help.sigmacomputing.com/docs/sparklineagg) and [Sparkline](https://help.sigmacomputing.com/docs/sparkline) (JSON data only) functions.

See [Create sparklines in a table (Beta)](https://help.sigmacomputing.com/docs/create-sparklines-in-a-table).

## Bug fixes

* The "tag" parameter in the [Export data from a workbook](/reference/export-workbook) (`POST /v2/workbooks/{workbookId}/export`) endpoint now works as expected.
* The [Add workbook schedule](/reference/post-workbook-schedule) endpoint (`POST /v2/workbooks/{workbookId}/schedules`) no longer fails when attempting to create a schedule that exports to Slack. To fix this issue, the nonfunctional `slackChannelName` option was changed to `slackConversationId`.
* Dynamically changing the source of a table in a data element using custom SQL no longer stops related columns from being available in child elements of the source table.
* Column descriptions added in a data model are now available in workbooks.
* When adding a data element that uses SQL as the source, the connection now correctly defaults to one that the user has access to use for SQL queries.
* Mobile view now includes a profile menu that provides users with the option to sign out of their Sigma account on a mobile device.
