Apple Releases Safari Technology Preview 144 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 144 includes bug fixes and performance improvements for Web Inspector, CSS, Web Animations, JavaScript, WebAuthn, Web API, Accessibility, Media, Security Policy, and Web Extensions.

The current ‌Safari Technology Preview‌ release is built on the Safari 15.4 update and it includes Safari 15 features introduced in macOS Monterey.

The ‌Safari Technology Preview‌ update is available through the Software Update mechanism in System Preferences 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 know it’s probably niche but please fix the memory issues when watching Twitch. Literally eats GB’s of memory.

But will the WebKit team ever implement the ES2018 feature (raised in 2017!) of RegExp lookbehind assertions ('https://bugs.webkit.org/show_bug.cgi?id=174931')? I mean it'd be nice not to switch to another browser just to visit a site like: https://russiaslosses.netlify.app ('https://russiaslosses.netlify.app/')

I used to think Safari was so good. Everyday I use it something goes wrong that works perfectly in Chrome or Firefox. Safari is terribly unreliable
Amen. I get so many issues with many sites or web based applications. Scrolling and the entire pages moves instead of scrolling giving you white space is one of the most annoying and frequent items. It has gotten better with rendering most things, but still sucks in comparison.
