Apple Releases Safari Technology Preview 163 With Bug Fixes and Performance Improvements

Apple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced 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 Feature
‌Safari Technology Preview‌ release 163 includes bug fixes and performance improvements for Web Inspector, Masonry Layout, CSS Custom Properties, Media Queries, CSS, Forms, Rendering, JavaScript, WebAssembly, Gamepad API, Web API, WebGL, SVG, Scrolling, Media, Accessibility, WebDriver, Safari Web Extensions, and more.

The current ‌Safari Technology Preview‌ release is version 16.4 and is compatible with machines running macOS Ventura and macOS Monterey.

The ‌Safari Technology Preview‌ update is available through the Software Update mechanism in System Preferences or System Settings 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.

Apple used to offer Safari for Windows. Since they are (supposedly) being forced to allow other rendering engines on iOS, maybe now would be a good time for them to make Safari cross-platform again...

Same, and I don't get it. It's just the web...what does Chrome *really* do that Safari doesn't? Aside from consuming incredible amounts of memory, that is...
I can take a brand new Mac out of the box, open Safari, and go to the Nike website (Apple Card 3% partner btw) and start scrolling through shoes. Eventually the images for shoes will stop loading for ones that have multiple color options so you just see a website sprinkled with pictures and blank white boxes. You have to scroll over the empty box for it to populate an image.

This is the most basic thing and Safari can’t get it right and hasn’t for a long time. However, Safari Tech Preview does for some reason. I’ve tried on Apple store computers and my own and it always fails.

Same here, 16Gb RAM and always get the low on memory or this page is using resources and asking me to close the page. Never happened before Ventura.
Many times on facebook, the page won't scroll down and I have to re-load the page.
Really infuriating
I've got 32GB on my Studio and 24GB on my MacBook Air M2 but I still receive that same message particularly when it comes to a variety of different web technology heavy websites. It has basically gotten to the point that I've moved back to Chrome. I really want Safari/Webkit to be a solid competitor to Chrome but Apple certainly make it difficult when these long standing issues are either being ignored or developers deny that they exist in the first place.

Good to know that Apple are still actually working on Safari. Sometimes I worry that they're close to throwing in the towel.

I hope so. Most iOS and Mac users around me use Chrome on their iPhones and Macs. Chrome already ruled Windows and Android, so locking Safari engine on iOS is pretty much the only last holdout from making the whole internet to be "Chrome-based."
