# What's new in Sigma

> Sigma release notes for Sep 26, 2025: Audit logging events for app-based two-factor authentication, OAuth redirect URI on connection forms, and more.

## Admin

### Audit logging events for app-based two-factor authentication (Beta)

You can now view app-based two-factor authentication login events in the audit logs.

### OAuth redirect URI on connection forms

Sigma now displays the redirect URI on your connection forms that OAuth providers should use when redirecting users back to Sigma after authentication.

## Data apps

### Input table editing on mobile

Users can now edit input table data on mobile devices. This update enables mobile data app workflows, including direct data input and row updates via actions.

## Functions and calculations

### Geography functions on Databricks (Beta)

All geography functions except for Centroid, Intersects, and Within are now available on Databricks connections. This includes the passthrough functions CallGeography and AggGeography. For more information, see [Geography functions](https://help.sigmacomputing.com/docs/geography-functions#/).

### Azure SQL connections now support record formulas and the ArrayAgg function

You can now use record formulas and the ArrayAgg function on an Azure SQL connection.

For more information, see [Generate and access structured objects](https://help.sigmacomputing.com/docs/generate-and-access-structured-objects) and [ArrayAgg](https://help.sigmacomputing.com/docs/arrayagg).

## Workbook elements

### New design for date and date range controls

Date and date range controls have a new design that enables navigating the controls with your keyboard, improving accessibility and usability.

### 3 digit zip codes on region maps

3 digit US zip codes are now supported when creating map visualizations. This allows for less granular visualizations in maps to be created.

For more information, see [Maps](https://help.sigmacomputing.com/docs/maps#/map---region).

## Workbook features

### Linked references in workbook template shares

Linked references to datasets are now included when you share a workbook template between organizations.

## Bug fixes

* When creating a linked input table, the modal now displays the write-back destination selection field first (above the list of columns) for improved visibility.
* After deleting a materialization schedule on a published workbook, the workbook no longer opens a custom view.
