# What's new in Sigma

> Sigma release notes for Feb 16, 2024: ConvertTimezone function enhancement, MakeDate function enhancement, and more.

## Functions

### ConvertTimezone function enhancement

The **ConvertTimezone** function now supports an optional *from_timezone* argument that allows you to specify the time zone from which the datetime value is converted. This argument can be used when the data's originating time zone differs from your organization's configured [account time zone](https://help.sigmacomputing.com/docs/account-time-zone).

For more information, see [ConvertTimezone](https://help.sigmacomputing.com/docs/converttimezone).

### MakeDate function enhancement

The **MakeDate** function now supports optional hour, minute, and second arguments that enable more precision when specifying the datetime components.

For more information, see [MakeDate](https://help.sigmacomputing.com/docs/makedate).

## Workbook elements

### Permanent filter icon display

The element toolbar for data elements now includes a filter icon at all times, regardless of whether a filter or control is already applied. This update enables quick access to filtering options for every data element added to the workbook.

## Workbook features

### Dynamic page visibility (Beta)

Dynamic page visibility allows you to restrict the visibility of individual workbook pages based on specific users and teams. By default, pages are visible to all users with permission to view, explore, or edit the workbook, but you can now choose from three options:

|                                        |                                                                                                                                                                         |
| :------------------------------------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Hide page from all users**           | Hides page from all users when the workbook is open in **View** or **Explore** mode.                                                                                    |
| **Show page to all users** (default)   | Shows page to all users when the workbook is open in any mode.                                                                                                          |
| **Only show to select users or teams** | Shows page to select users and teams when the workbook is open in any mode. Hides page from unselected users when the workbook is open in **View** or **Explore** mode. |

Page visibility settings apply to **View** and **Explore** mode only. The workbook owner and all users with **Can edit** access to the particular workbook can access all pages in **Edit** mode, regardless of page visibility settings.
