Apple on Wednesday released Safari Technology Preview 123, the latest version of their developer preview web browser. The preview version of Apple’s popular browser offers developers and other interested users the ability to try out features that may or may not, debut in future public release versions of Safari.
Safari Technology Preview release 123 includes bug fixes and performance improvements for Web Inspector, CSS, and Web API.
The current Safari Technology Preview release is built on the new Safari 14 update included in macOS Big Sur.

While the preview is intended for use by developers and advanced users, in order to provide Apple with feedback on the development of the Safari browser, it can be run side-by-side with the release version of Safari. The app doesn’t require a developer account to download and install. For more information, visit the Safari Technology Preview website.
