safaripreviewiconApple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced on March 30. Apple uses Safari Technology Preview to test features that may eventually be introduced in the release version of Safari.

Safari Technology Preview release 6 includes bug fixes and updates for JavaScript, CSS, Web APIs, Web Inspector, and Media.

The Safari Technology Preview update is available through the Mac App Store to anyone who has downloaded the browser. Full release notes are available on Apple's Safari Technology Preview website.

Apple's goal with Safari Technology Preview is to gather feedback from developers and users on its browser development process. 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.

But if the version or build number is always outdated for sometimes more than a week it is only for people who are not using OS X betas. Or am I wrong? It even states it is only for 10.11.4 and 10.11.5 like I just posted. But there is always this second build number what looks newer...

I always switched back when a new OS X beta was released and had to wait for the new Technology Preview. The only difference I recognized was that it broke the 1Password extension in the third version I think.

Hoping for Safari 10 on Monday now. :) Or might there even be a new Browser like Edge? ;) The nightly version from webkit.org has still the same build number as the normal Safari. Normally it's always newer than the Technology Preview.
It should not be used as main browser. It is for us programmers and web designers to test web apps, to make sure they are compatible and working when it will be released and it is not guaranteed to be stable or work with password apps.
That said the version number XXWWW.Z the first two digits are 11 for El Capitan, next are the webkit version. The second number should start with 12WWW as it's compatible with next Mac OS X, but I don't know why it doesn't.

There's not really any user facing changes, instead it's mainly better web standards support, for changes see:

Nearly 100% ES6 (or JS6, or ES2015, or whatever) - http://kangax.github.io/compat-table/es6/ (load this in Safari Technical Preview, and then look for Safari 9 which is at 53%)

and a general mix of web standards - http://caniuse.com/#compare=safari+9.1,safari+TP

I think it's always just a newer build of Safari maybe with the Develop and/or Debug menu enabled by default. But it comes too late for the betas and I can enable those menus in the normal Safari too. It would be no problem to switch every time if the settings and extensions will sync too, but they don't. Only bookmarks and tabs over iCloud.


? o_O


I will install it now again and have a look at the version and build numbers.

It's again just slightly newer build and comes too late for beta testers. The Develop menu is there by default, what you can enable in the normal Safari too. But the Debug menu is missing and all my settings and extensions.

Does any one know what the second build number means?
