This release delivers a comprehensive overhaul of the authentication flow, including a unified school-branded sign-in shell, improved device management with new-device alerts, and a streamlined sign-up process. We've also significantly hardened security by addressing webhook SSRF vulnerabilities, fixing payment gateway bypass risks, and implementing robust password-guessing protection. Additionally, Nginx has been tuned for high performance with HTTP/2 and persistent connections, ensuring a faster and more scalable experience for all users.
