Apple Releases Safari Technology Preview 42 With Bug Fixes and Feature Improvements

by

safaripreviewiconApple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced more than a 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 42 includes fixes and improvements for Files and Directory Entries API, Clipboard API, Fonts, CSS, Web API, WebDriver, JavaScript, Accessibility, Media, Rendering, WebGL, and Web Inspector. Today's update also implements Payment Request features.

With Safari 11 now available in macOS High Sierra, 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.

Can't get any webpage to load after this update. I get the "This webpage was reloaded because a problem occurred" prompt after launching and I don't even have a homepage set.

Edit: It was my content blocker. Had to uninstall and reinstall AdGuard and now all is working properly.

IMAX Reacts to iPhone Duo's 1:1.4 Aspect Ratio Displays

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...
