The Safari Technology Preview 238 update introduces broad improvements across Apple’s experimental browser platform. Apple released the latest version to refine core web technologies and improve developer testing stability.
Safari Technology Preview was first launched in 2016 as a public testing environment. Since then, it has allowed developers and early adopters to preview features that may later appear in the standard Safari browser.
