Improvements to existing features

Improved website tracking compatibility to work with delayed JavaScript loading, giving you more flexibility in optimizing your site's performance.

Enhanced browser compatibility to ensure tracking continues working smoothly as browsers update and evolve. This maintains optimal performance across all current browser versions based on global browser usage patterns.

Please refer to Browser Compatibility Statement for supported web browser versions.

Enhanced form monitoring accuracy to prevent the processing of web form submissions with values that have not passed website validation checks.

Added a simplified visitor retrieval function that makes it easier for website developers to access visitor information for personalization and custom use cases.
