safaripreviewiconApple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced one year 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 33 includes fixes and improvements for JavaScript, WebRTC, Media Streams and Capture, Media, CSS Grid, Web API, Rendering, and Web Inspector.

Today's update also includes a specific bug fix that allows Netflix to properly work with Safari when using AirPods and it addresses an issue causing stuttering audio in YouTube when the page changes visibility.

With Safari 11 now available to developers through the macOS High Sierra beta, Apple is providing two versions of Safari Technology Preview, one for macOS Sierra users and one for those using macOS High Sierra.

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.

Open any youtube vid and let it play a bit, move the video timeline slider back, watch the image freeze. It's been like this since version 30. If anybody cares.
