Apple Releases Safari Technology Preview 90 With Bug Fixes and Performance Improvements

by

safaripreviewiconApple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced three years ago in March 2016. Apple designed the ‌Safari Technology Preview‌ to test features that may be introduced into future release versions of Safari.

‌Safari Technology Preview‌ release 90 includes bug fixes and performance improvements for Web API, Media, WebRTC, WebGPU, and Web Inspector.

The new ‌Safari Technology Preview‌ update is available for both macOS Mojave and MacOS Catalina, the newest version of the Mac operating system that was introduced at the June Worldwide Developers Conference.

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.

Preview 90.
The "Release" numbering makes enough sense within the Preview, but little to no sense when you compare it with the production release versioning. As you said, it's probably because they roll features instead of the entire build.

You want to talk about something that makes no sense whatsoever? User agent strings.

codecs that will never be supported
I don't know, didn't Apple finally join the "Alliance for Open Media"*? Could be nothing more than "me, too" FOMO resume-fodder for Apple, or it could be that they took a good look at the "bag of hurt" (version 2.0) that is HEVC licensing and decided AV1 wasn't that bad after all. The tell will be GPU support for AV1 primitives.

(*Talk about your loaded names. I'm sure "open media" stalwart Google will start offering everything on YouTube for DRM-free download, without any ad tracking, sometime next week...)
