Apple Releases Safari Technology Preview 115 With Bug Fixes and Performance Improvements
Apple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced four years ago in March 2016. Apple designed the Safari Technology Preview to test features that may be introduced into future release versions of Safari.
Safari Technology Preview release 115 includes bug fixes and performance improvements for Web Audio, JavaScript, Web API, Media, CSS, WebAuthn, Selection API, and WebRTC.
The current Safari Technology Preview release is the built on the new Safari 14 update included in macOS Big Sur with support for Safari Web Extensions imported from other browsers, tab previews, password breach notifications, web authentication with Touch ID, and more.
The new Safari Technology Preview update is available for both macOS Catalina and macOS Big Sur, the newest version of the Mac operating system.
The Safari Technology Preview update is available through the Software Update mechanism in System Preferences to anyone who has downloaded the browser. Full release notes for the update are available on the Safari Technology Preview website.
Apple's aim with Safari Technology Preview is to gather feedback from developers and users on its browser development process. Safari Technology Preview can run side-by-side with the existing Safari browser and while designed for developers, it does not require a developer account to download.
