Launched in March 2016, the browser Safari Technology preview, as the name suggests, it was created to allow developers to test features to be introduced on a permanent basis. Yet downloading it is very simple, does not require a developer account and can be used alongside the stable version of Safari for macOS, so it has spread even among the “simple” users of Apple’s OS who are curious to test the preview news.
The list of changes introduced in the version 138 Safari Technology Preview is very full-bodied, a sign of the work done by the designers to improve the previous version: the corrections aimed at increasing the speed are several, and concern Web Inspector, CSS, Experimental Model Element, Media, Web Animation, WebAuthn, SVG , Web API, Service Workers, WebRTC, WebAssembly and Web Extensions.
Apple made the Safari Technology Preview browser to test features that may be introduced in future releases. The Safari Technology Preview update is available via the dedicated menu System Preferences for all those who have already installed one of the previous versions. The full release notes for the update are available on the Safari Technology Preview website (link in SOURCE).
Obviously, Apple’s goal with Safari Technology Preview is to gather feedback from developers and users. This browser can still run in parallel with the system Safari browser on macOS Monterey and macOS Big Sur, and although it is aimed at developers, does not require a specific download account.
