Apple Releases Safari Technology Preview 65 With Bug Fixes and Feature Improvements

[MacRumors]

Apple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced over two years 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 65 includes bug fixes and feature improvements for the Storage Access API, Media, Apple Pay, Payment Request, Shadow DOM, Fetch API, Service Workers, Web API, Web Inspector, WebGL 2, Web Assembly, and Safari Extensions.

The new Safari Technology Preview update is available for both macOS High Sierra and macOS Mojave, the newest version of the Mac operating system that's currently being beta tested by developers and public beta testers.

The Safari Technology Preview update is available through the Software Update mechanism in the Mac App Store (or in System Preferences in Mojave) 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.

Gmail (web) is still super slow to scroll through large amounts of text (vs Chrome).

Can it run 4K YouTube videos yet?

I wish it fixed the Graphical Glitches with YouTube on full screen while using Intel Graphics on MBP’s...

That's Google's stupid idea...

Can it run 4K YouTube videos yet?

nope and I hope apple never will. until youtube switches over to HEVC.

 

[jonnysods]

Man, when is a GM of Mojave and iOS 12 going to be ready? They don't seem close to final or near final right now!

Since I used to be able to watch 4K YouTube videos in Safari and in the YouTube App on my iPhone I‘m pretty sure it‘s Google who removed that ability.

Why can’t it anyways? I did notice that. You need Firefox with that web hack.

What’s that? Can you explain please .

4K video? Hell, I've have SD videos freeze from various websites with every update.

Typical Apple, make everyone conform to your standard, not the one everyone else is using.

Google made VP9 and it’s worse than HEVC, which everyone else uses. Apple didn’t make HEVC.

SD videos are also nothing to do with the above codecs, which are made specifically for 4K content.

Everyone else? VP9 isn't anywhere close. Apart from Youtube, which is the only major force Google force their Standard. VP9 is free, but it is still a Google standard. Forge and Lead by Google.

HEVC is an open, industry standard, but it has patents fees problem. And a gentle reminder, neither AV1 nor VP9 is patents free.

So all those new builds and its getting 2 more points then my iOS 11.4 Safari on iPad Pro. Whelp looks like I shouldn’t expect any meaningful improvements to website compatibility or formatting weirdness.

HEVC is also vastly more efficient with resources compared to VP9 I believe.

These ones.

In all fairness, it depends. I mean the scene are still using x264 for a reason. HEVC is now slightly better than VP9, and has the potential to be even better, it take years to fine tune an encoder.

These ones.

Yikes!

Macos Mojave. Major issues. Daily new starts required.

Yikes!

It's a Safari bug with the new 2018 MacBook Pro's while watching YouTube videos on full screen with the Intel Graphics.

 

[VictorTango777]

What was the reason for removing native RSS support and Bonjour browser?

Does it fix high memory usage after watching Netflix video for an hour?

 

[macintologist]

What's an example of a technology that was first previewed in Safari Technology Preview that eventually made its way into Safari?

Yeah it's not ready. Even a month from now feels too soon.

Recent example would be blocking autoplay videos. I used the Safari Tech Preview just for that before it went mainstream.

Yep, 4K, no issue. And I have a 2012 21.5“ iMac, so no high-end hardware at all. What Mac are you using and are you sure there‘s no hardware issue? My iMac was stuttering and freezing from time to time when my hard drive began to fail but Disk Utility was telling me everything was fine everytime I checked. Finally upgraded to a SSD yesterday after using it with an old 2.5“ hard drive connected to a SATA to USB cable for two years. Everything is super fast now, couldn‘t be happier!
