Apple Releases Safari Technology Preview 15 With Bug Fixes and Feature Tweaks

by

safaripreviewiconApple today released another 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 15 includes bug fixes and updates for fetch API, JavaScript, CSS, web APIs, Web Inspector, media, accessibility, URL handling, and Safari Extensions.

Starting with release 14, Safari Technology Preview includes regular updates and bug fixes for Safari's WebDriver implementation.

The Safari Technology Preview update is available through the Software Update mechanism in the Mac App Store to anyone who has downloaded the browser. Versions are available for developers running both macOS Sierra and OS X El Capitan. Full release notes for the update are available on the Safari Technology Preview website.

Apple's goal with Safari Technology Preview is to gather feedback from developers and users on its browser development process. Safari Technology Preview can be run side-by-side with the existing Safari browser and while designed for developers, it does not require a developer account to download.

The article says it includes bug fixes to fetch API, not that it's a new feature.

Anyway, which browser would you recommend then?
Yes, bug fixes on the fetch API that is still not available in the public channel.

I'm really happy with Chrome v56 on the Canary channel. Features, performance, RAM consumption, and energy have never been better in macOS.

It's for web developers to know what's coming down the pipe and make fixes/enhancements to projects accordingly. It's not meant for the average Joe to be using as a daily browser.

Safari needs to catch-up in the HTML5 test score. Even Microsoft beats it now!

Production theater company IMAX has responded in a mixed way to Apple's embrace of a 1:1.4 aspect ratio on the iPhone Duo's inner and outer displays. The boxier ratio happens to be very close to the classic "full-frame" IMAX 1.43:1 aspect ratio, which comes from the geometry of the company's original 15-perforation/70mm film system. In response to an X post from someone wondering if we'll see...
