Apple Releases Safari Technology Preview 65 With Bug Fixes and Feature Improvements

by

safaripreviewiconApple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced over 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 65 includes bug fixes and feature improvements for the Storage Access API, Media, Apple Pay, Payment Request, Shadow DOM, Fetch API, Service Workers, Web API, Web Inspector, WebGL 2, Web Assembly, and Safari Extensions.

The new Safari Technology Preview update is available for both macOS High Sierra and macOS Mojave, the newest version of the Mac operating system that’s currently being beta tested by developers and public beta testers.

The Safari Technology Preview update is available through the Software Update mechanism in the Mac App Store (or in System Preferences in Mojave) 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.

Macos Mojave. Major issues. Daily new starts required.
Yeah it's not ready. Even a month from now feels too soon.

Yikes!
It's a Safari bug with the new 2018 MacBook Pro's while watching YouTube videos on full screen with the Intel Graphics.

HEVC is also vastly more efficient with resources compared to VP9 I believe.
In all fairness, it depends. I mean the scene are still using x264 for a reason. HEVC is now slightly better than VP9, and has the potential to be even better, it take years to fine tune an encoder.
