safaripreviewiconApple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced almost two years ago in March of 2016. Apple designed the Safari Technology Preview to test features that may be introduced into future release versions of Safari.

Safari Technology Preview release 49 includes bug fixes and feature improvements for Service Workers, Fetch, Intelligent Tracking Prevention, CSS, Rendering, SVG, JavaScript, Web Inspector, Media, Storage, Security, and Accessibility.

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.

I've been having a back-and-forth with the official WebKit Twitter account through PM. We've concluded that HTML5test misreports scores if you're not using the https version of the site, because some of the features require a secure connection.

Apple has completely lost control of their browser. One cannot get thru' a day's worth of browsing without launching Google Chrome. Safari has become Internet Explorer !

Great Work Apple !
