The new version of Apple's experimental browser, Safari Technology Preview reached version 86 yesterday afternoon and continues its good rhythm of updates. In this case, as in previous versions, it adds the typical changes and improvements in performance and updates for the browser extensions, Fetch, JavaScript Web API, and also Apple improves compatibility with the new operating system released for developers this June, macOS Cartalina.
The new features that are being implemented in this browser are what we see in the final versions of Safari and that is why if we control a little we can enjoy the improvements before the bulk of users. The truth is that being able to use both browsers at the same time, the Safari Technology Preview and Safari, allows us an interesting game to see the differences between them without having to complicate ourselves in terms of partitions or possible failures of the test browser. You can download it totally free and find more information en el sitio web dedicado a Safari Technology Preview.
