Apple Releases Safari Technology Preview 4 With Bug Fixes and Feature Tweaks

by

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 4 includes a long list of bug fixes and updates for networking, media, JavaScript, CSS, web APIs, Web Inspector, rendering, and accessibility.

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

Are you really going to make an article for every insignificant beta version of a web browser that is basically just bug fixes?

I have been using the technology preview version over the standard version of safari. I have not had any significant issues and it runs faster, and that makes me happy. Truly Safari is snappier.

It's far more advanced. Of course it's going to run faster and more robust.

Installed and using as my main browser... so far so good. Exactly what is 'different' about it? Is this a whole new engine or just a few developer tweaks? Looks identical to me so far.
Lots of new foundation, far more advanced features, better scaling, etc.
