safaripreviewiconApple today released a new 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 38 includes fixes and improvements for Fetch API, Web Payments, CSS, Web API, Media, Apple Pay, Web Inspector, and WebDriver. Today's update also enables the Beacon API by default and implements new Beacon API features.

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.

I have a question for you folks who are running this preview, now that the beacon api has been enabled.

Is there an option/setting to turn that off?
Normally everything is unchecked in Develop/Experimental Features, if you install it for the first time except for the Beacon API this time.
It seems there are four new features because I always check everything. Even though I don't have any clue what all that means. ;)

Interesting... this is the first time the Safari Tech Preview update hasn't shown up for me in the App Store immediately after I read the article about it here on MacRumors. Hmm. o_O
It hasn't shown up there for me too since at least the last three versions. I Just wanted to ask if anyone else experienced this.

As was pointed out to me recently, if you enable everything under Develop > Experimental, it's 464. (On Sierra.)
Really? I get a score of 474 with all the experimental features activated.

What is Beacon?
I wondered this, too. I found this documentation ('https://developer.mozilla.org/en-US/docs/Web/API/Beacon_API'). The "Why Use Beacon?" section gives an example use case.

Does Preview version support Youtube 4k already or still nothing ?
Seems to work for some videos I tried now. Maybe the other ones lied about being 4K or need Flash what Safari seems only support for very old and/or long videos that are Flash only.

A few days ago I checked it with the previous version and found nothing higher than 1440p.




Edit: Forgot to prove that it's really Safari.

Wait really?
Not really. Preview 38 459/555.

Preview 38 is Safari 11.1 listed string on macOS 10.12.

Interestingly, Safari 11 beta 6 that can be downloaded for El Captian and Sierra is 455/555. The difference is no beacon enabled yet and Subresource integrity under the Security tests.

By comparison: Safari 10.2 currently for macOS 10.12 is 419/555.

WebGL 2 is currently enabled in 10.2 but going under additional testing for 11 (beta 6) and 11.1 (Preview 38)

Safari 10.2 lacks Peer to Peer 0/38 points, Scripting 0/3 for Modules.k

Outside of shoring up Forms, Peer-to-Peer Media Stream recorder and Screen Capture, Writable streams, Audio speech recognition, and possibly Device motion/orientation with WebVR, plus the Web Animations API nothing new features are untouched.

What's always ongoing will be future web standards that are yet to be flushed out like WebGPU (https://gpuweb.github.io/admin/cg-charter.html), updates to current HTML 5.x (5.2/5.3 RC) [if necessary], CSS 1/2/3 full support(https://www.w3.org/Style/CSS/) and possibly SVG 1.2/2.x/MathML, etc.

Nothing drastically is missing, unless you think having Forms support and web applications are a do or die scenario between Safari and Chrome.
