During March 2025, work focused on migrating the ReCAPTCHA integration in the pkp/pkp-lib repository to recaptcha.net, addressing privacy compliance requirements while maintaining existing validation logic. This update involved backend development and API integration using PHP, with changes applied to FormValidatorReCaptcha.php and PKPTemplateManager.php to ensure the correct domain loaded seamlessly across deployments. The implementation preserved user experience by avoiding any UI modifications and maintained backward compatibility through careful refactoring. No major bugs were addressed during this period, and the primary contribution centered on enhancing privacy compliance and reliability in form validation workflows within the repository’s backend infrastructure.
