Apple Releases Safari Technology Preview 32 With New Features for Safari 11 in macOS High Sierra

[MacRumors]

Apple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced one 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 32 includes new features for Safari 11, which is built into macOS High Sierra. A list of the new additions is below:

WebRTC and Media Capture
WebAssembly
Auto-Play Improvements

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.

IT IS!

IT IS!

Well now - I haven't been using this browser, but I think I am going to start right now!

The article should be clearer–even the Sierra version has the High Sierra features, including Autoplay and automatic reader functionality. So, that makes me even less interested in installing HS.

Here's a pic of the new website settings pane:

Edit: the app is killing my CPU for some reason. Well, it's a preview after all.

i guess this will stop all the 'what about WebRTC' comments

 

[isomorphic]

html5test.com returns 454!

WebRTC is mostly checked!

 

[Guy Clark]

Is it available for macOS Sierra?

Just answered my own question YES

 

[mkeeley]

So I presume webrtc will have the leak problems it has in chrome and ff?

Can WebRTC be turned off?

 

[neander]

Youtube does not particularly like this update.. its even worse freezes than the last Preview, I have 2 Mac Minis. No such on regular Safari.

Everything looks good though.

 

[mkeeley]

Can WebRTC be turned off?

I couldn't find an option, might have missed it though.

 

[KALLT]

I couldn't find an option, might have missed it though.

Unfortunate, if true. There are concerns about IP leakage when using a VPN, caused by WebRTC. Not sure if this was just a flaw in Firefox and Chrome.

IT IS!

This is fantastic! I opened a USA Today article didn't have to shut off a useless video of the article I was about to read. I love it!

WebRTC
Isn't this what everyone kept asking for?

By the way, is there some special reason, that I'm missing, why this article, about Safari on macOS (and only macOS) is on the iOS blog, and not on the Mac blog?

Even less? HighSierra is the most exiting macOS version even with Metal 2, eGPU support and all the rest! I hope you mean installing beta.

Not me. Seems to be a leaky old thing unless they've done things differently.

 

[mkeeley]

It does seem to leak the same as chrome and ff.

 

[Cougarcat]

Yes, but it's mainly (important) low-level features that will be of benefit later down the line. I am also not keen on installing a beta with a brand new file system.

This. I tend to be pretty early on the "install the new OS" wave (once it's golden), but file systems... hey, that's where I keep all my stuff! I'm gonna wait a bit and let a whole lot of other people play "crash test dummy" before I install that.
