    Apple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced three years ago in March 2016. Apple designed the Safari Technology Preview to test features that may be introduced into future release versions of Safari.

    Safari Technology Preview release 82 includes bug fixes and performance improvements for Web API, JavaScript, Media, Storage, CSS, Accessibility, Web Inspector, Web Driver, Web Authentication, and WebGPU. A new browser change means that when you uncheck "Allow websites to ask for permission to send notifications," it will disable prompting for HTML5 notifications.

    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 was released to the public in September 2018.

    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.

    This has to be the longest beta development in history...

    You seem to have misunderstood, this is just a persistent Safari preview, we're testing features that trickle down to regular Safari over time, nothing more.

    https://html5test.com/

    Score: Either -∞, 0, or Ø, depending upon your mathematical axioms and inclinations.

    (html5test is not working for me at all in Preview 82, on a freshly-upgraded Mojave 10.14.5. Moreover, I had to enter the URL twice into the address bar to even get it to visit the site. I tried resetting/clearing everything including "Experimental Features" and nothing worked. Guess I'll use Firefox while waiting on 83.)

    EDIT: It's not working for me in Firefox (Dev/Aurora channel), either, so it may be my end, or html5test itself may be broken?

    I tried on both Safari 12.1 and the Tech preview: initially nothing happened on either of those: same symptoms as you described. ( Also, the url needed to be loaded twice on both browsers)

    Then I tried a much more elaborate test:
    https://www.antutu.com/html5/

    results:
    12.1: 41638
    12.2: 41951

    And then - oh magic - I could anyways run https://html5test.com/

    results:
    12.1: 474 OUT OF 555 POINTS
    12.2: 489 OUT OF 555 POINTS

    (both ending with some kind of error)

    Weirdly, now I can run html5test without it hanging and without errors.

    I'm getting 499 on 12.2R82 with all experimental features enabled.
