Feedback for future updates
Apple launched Safari Technology Preview in 2016. It is hoped that this ongoing public beta will provide helpful feedback on bug fixing in Safari. The Technology Preview can be used parallel to the regular version of Safari; it does not replace it during installation.
Safari Technology Preview is available for macOS Big Sur and its predecessor Catalina and is based on Safari 14. With this update, Apple introduced the new tab preview, warnings for insecure passwords and support for extensions to other browsers. More details on the latest update can be found here.
