# What's new in Sigma

> Sigma release notes for Mar 28, 2025: Unified header on the Sigma home page, input tables now supported on Amazon Redshift connections, and more.

## Search and discovery

### Unified header on the Sigma home page

The home page header has been redesigned to match the [recently updated workbook and data model UI](https://help.sigmacomputing.com/changelog/2025-03-07#redesigned-user-interface-for-workbooks-and-data-models). The change is aesthetic and does not impact any functionality. The new updated homepage header has rolled out for some organizations, and will continue to be incrementally rolled out over the coming weeks.

## Workbook elements

### Input tables now supported on Amazon Redshift connections (GA)

Input tables are now compatible with Amazon Redshift connections. These dynamic workbook elements support structured data entry that allows you to integrate new data points into your analysis and augment existing data.

For more information about input tables and how to use them, see the following documentation:

* [Intro to input tables](https://help.sigmacomputing.com/docs/intro-to-input-tables)
* [Create new input tables](https://help.sigmacomputing.com/docs/create-new-input-tables)
* [Edit existing input table columns](https://help.sigmacomputing.com/docs/edit-existing-input-table-columns)

### Detach a control from an element

If you want to remove an element as a target of a control, you can now detach the control from the element from the element's filter menu.

## Bug fixes

* Materialization schedules owned by users deactivated after March 25, 2025 transfer to the admin performing the deactivation, or if specified, the user chosen to receive the deactivated user's documents. Materialization schedules owned by users deactivated prior to that date fail to run and materialized elements might display an error.
