Frigade 2.0 introduces an enhanced audience builder tool designed to target Flows to specific user groups based on their behaviors and attributes. This tool enables users to create complex audience segments using a visual interface without the need for custom targeting code, which is accessible under the "Targeting" tab of a Flow. It also offers a real-time preview feature for users to verify their targeting strategies effectively. Users are encouraged to explore further documentation on Audiences and Targeting to maximize the benefits of the new tool.
