As web standards shifted toward HTTPS and more rigorous browser requirements, the 21.4 update integrated better Git support and SFTP connectivity, ensuring that the deployment of sites was as secure as it was efficient. It moved away from being a mere "drag-and-drop" builder and leaned into being a robust Integrated Development Environment (IDE) that respected the logic of professional coding standards.
