# April 7, 2026

This update includes several improvements to module variables, based on feedback.

### New variable types

Variables can now be numeric, date, datetimes, custom objects (called variable groups), or arrays of each.

#### Variable groups

Variable groups become an Object in a workflow. This is particularly useful for arrays of objects, which can be used for mapping.

The example above shows a mapping in progress. The Perk "Upgrade to GOLD" is mapped to the "GOLD" membership tier filter, with the option to add additional rows.

Only one layer of nesting is allowed.

### Assisted variable descriptions

Assisted variables now support descriptions, which help provide details for users.

### JSON editor

Variables can be edited as JSON, which may be helpful for complex or AI-assisted workflows.
