Apple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced three 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 91 includes bug fixes and performance improvements for Javascript API, JavaScript Performance, Media, Web API, Rendering, Pointer Events, WebDriver, Web Inspector, and WebGPU.
Today's Safari Technology Preview update disables TLS 1.0 and TLS 1.1. Apple in October 2018 said that it plans to end support for TLS 1.0 and 1.1 in March 2020, and has recommended that apps adopt TLS 1.2 instead.
TLS 1.2 is the standard on Apple platforms, and according to Apple, represents 99.6 percent of connections made from Safari. TLS 1.0 and 1.1 account for less than 0.36 percent of connections.
The new Safari Technology Preview update is available for both macOS Mojave and MacOS Catalina, the newest version of the Mac operating system that was introduced at the June Worldwide Developers Conference.
The Safari Technology Preview update is available through the Software Update mechanism in the Mac App Store 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.
