Apple Releases Safari Technology Preview 38 With Beacon API Enabled by Default

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.

Thanks for all the info!

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.

I know that embedded videos worked before but that seems like a straight up Youtube video.
Great, will install and take it for a spin. Only reason I still use Chrome sometimes is because of that.

Edit:
Did a small test and some MKBHD video had no 4k option but then a 4k specific video had. I think it has to do how long ago the videos were uploaded and how they were converted at the time. I think the new format is the one Safari does not support yet so probably only old videos will have the 4k option

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.

Safari Technology Preview 39 is out...and it crashes on launch for me. So I reinstalled it...still crashes on launch. Whoops!
