    Apple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced more than a 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 47 includes bug fixes and feature improvements with an experimental implementation of the Storage Access API, updates to Service Workers, and improvements to Media, Rendering, Web Inspector, and the Clipboard API.

    Today's update also includes mitigations for the Spectre hardware vulnerability that impacts Apple's Macs. Spectre fixes were previously added to the release version of Safari with yesterday's release of a supplemental update macOS High Sierra 10.13.2.

    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.

    Dear MR, earlier you used to give a very valuable piece of information to users, called build number.

    Had you given this, it would have been easy to figure out if my Safari 11.0.3 (13604.5.5) is good enough and contains the relevant updates or not.

    Still 464 out of 555 for me. 13" 2015 MBP, i5 2.9 CPU.

    I know other people have had higher scores than me, I have all developer features enabled.

    I’m not going to free test software for Apple anymore. Bugs are mainly reported as duplicated and ignored anyway. My life time is too short and precious to waste playing the good samaritan for a multi billion dollar company. They shall simply pay us for testing, or simply employ more internal testing staff.

    Anybody having problems with some pages loading?

    Tried going into a state page to renew a drivers license and the bar hung one inch in. (But I was able to reach the page using a Tor node in Sweden, LoL.)

    I was just being a smartass - it was an oblique reference to the VW diesel-gate scandal where the software in the car could detect when it was being tested for emissions and then reported back results that were better than reality.

    He's making a joke about the Volkswagen emissions scandal. :)
