    Apple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced one 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 27 includes fixes and improvements for JavaScript, Web API, Rendering, CSS, Web Inspector, Media, Accessibility, WebCrypto, and more. Browser changes include a new "Reload Page From Origin" option, which reloads a page without using cached resources, and the removal of the Disable Caches option from the Develop menu. Equivalent functionality is available using the Web Inspector's Network tab.

    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.

    I'm a big fan. I actually use it exclusively vs Safari 10.1.1, which I haven't touched in over a year.

    It's my browser of choice since its debut. I use it almost exclusively. The xception is when I need to perform cross-browser testing. STP has been ultra-stable and has performed extremely well for me.

    I'll save that one guy trouble and just post the 419 score now.

    One day one of these releases is going to score 555 and that guy will suddenly have free time.

    I've used it exclusively since it came out. Never had a single issue. It's been rock solid.

    Though before STP I used to use the nightlies from and update every few days and don't really remember ever having issues with those either, FWIW.

    Dear Apple:
    When I ⌘-click a link in STP in regular mode, I don't have the ability to open the URL in a new private mode tab/window.

    He makes a good point though, I use Safari almost exclusively but there's no doubt Chrome is more compatible. I read a few developer blogs and apparently Apple implement certain APIs in weird/proprietary ways and this is largely why sites like Mega only run with full compatibility on Chrome.

    Dear John,
    Apple will not hear this feedback. Fill out here to have it read:

    A few weeks ago I reported there that Safari should support disabling cache when the inspector is open (like chrome has had for years) since Safari only let you either alls have cache enabled or always disabled. At first they responded quickly laughing at the idea. Though I persisted at which time they eventually recognized the issue, and then within a couple weeks it rolled out in this 27 update, and was the number 1 bullet in the release notes. So while the Apple Feedback or posting here won't get you anywhere in general, filing actually bug reports will get looked at, and possibly resolved depending on if they agree.
