safaripreviewiconApple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced 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 21 includes bug fixes and updates for JavaScript, Fetch API, IndexedDB 2.0, CSS, Rendering, Web API, Accessibility, and Web Inspector.

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 goal with Safari Technology Preview is to receive 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.

So hard for me to enjoy Safari when there is no way to stop autoplay. That is such a huge nuance on some websites and it requires hoops to trick Safari into not doing it.
Is it really that annoying? Plus you can mute tabs..
