# What's new in Sigma

> Sigma release notes for Oct 13, 2023: Regular expression (RegExp) text match filtering, conditional formatting in input tables, and more.

## Filters and controls

### Regular expression (RegExp) text match filtering

New RegExp text match filters enable you to filter text columns based on specified patterns, including text strings, character classes, ranges, etc. These filters support the RegExp syntax and behavior of the connected CDW or DBMS.

|                           |                                                            |
| :------------------------ | :--------------------------------------------------------- |
| **Matches RegExp**        | Includes values that match one or more specified patterns. |
| **Does not match RegExp** | Excludes values that match one or more specified patterns. |

Use the disjunction operator ( | ) to filter multiple values. For example, `abc|xyz` filters values that contain "abc" or "xyz."

## Workbook elements

### Conditional formatting in input tables

Add rules based on specified conditions to format single colors, color scales, or data bars in input table columns. Access conditional formatting in the **Element format** panel, or open a column menu and select **Conditional formatting**.

### Hyperlinks in input tables

Add hyperlinks to input table columns. In the column menu, select **Transform** > **Set link**, then choose a column as the link source or create URLs with a custom formula.
