Apple Releases Safari Technology Preview 3 With Extensive Tweaks and Bug Fixes

by

safaripreviewiconApple today released a new update for Safari Technology Preview, the experimental browser that launched on March 30. Release 3 includes a long list of feature tweaks and updates to JavaScript, CSS, Web APIs, Web Inspector, Accessibility, Rendering, Media, and Networking, plus bug fixes.

Release notes are available on Apple's Safari Technology Preview website.

The Safari Technology Preview update is available through the Mac App Store to anyone who has downloaded the browser.

Apple's goal with Safari Technology Preview is to gather feedback from developers and users on its browser development ahead of launch. Safari Technology Preview can be run side-by-side with the existing Safari browser and while aimed at developers, it does not require a developer account to download.

All I want for Christmas is a desktop browser that doesn't autoplay videos.

Here's an HTML5 comparison of Safari Preview 9.1.1 vs 9.1 vs 9.0. http://beta.html5test.com/compare/browser/6622362e7251ac62/54b79a2e71e1c3a1/safari-9.0.html

Since Apple ignores basic usability with not showing icons in the tab bar, this safari browser can rott on in meaninglessness. What a pity.

As far as you're concerned, let it rot. For those of us who don't notice the icons, I see no great reason to put them there. Every time this "problem" is pointed out to me, I proceed to forget about it because it seems like a pretty small thing to get upset about.

Just downloaded this for the first time. I haven't had any real issues with Safari recently, but any improvements to stability and HTML/CSS/Javascript updates are always welcome of course.

I like that Apple is doing more to get their beta software in the hands of more people to get it perfected ahead of time.

When there are many tabs open, dont you think it would be much faster to recognize the content of the tab, when you see the icon of the tld? Like an apple in case of macrumors?

Bingo! This removal of graphical elements (especially shapes / icons... or using nondescript ones), removing color, or even possibly things like hiding aspects of the URL are bad UX/UI moves.

Well in Firefox Nightly (v49) and the current Safari Technology Preview (5) CSS Grid is now enabled by default/unprefixed so you don't need to mess with any of that!

But for future reference you will likely encounter other things behind flags (prefixes are being killed thankfully but many things are still prefixed) so...

For features behind flags search in the URL/ominbox: For Chrome & Opera go to/search 'chrome://flags', for Firefox go to 'about:config', not sure about Webkit/Safari but they may not have any flagged features yet anyway. Then there will be a settings page with a bunch of features in development that you can turn on if you want to try them out, these can affect the stability of the browser so be warned.

For prefixes, just prefix the property or value with the vendor prefix (-ms-, -o-, -webkit-, -moz-) and use it as you normally would (there are occasionally syntax differences which you may need to look up). For example (and kinda redundant now):

body {
display: -webkit-grid;
-webkit-grid-columns: auto;
-webkit-grid-rows: auto;
}

There's a wealth of info for support for CSS and JS on caniuse.com, which i recommend checking out. ;)

Thanks Josh... most of that is what I've found. But, supposedly, there is a way to enable it in Safari (but, I'll try again with the most recent, if it's on by default!). Lots of stuff references turning it on in Safari, but I couldn't find any way to do so.
