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 release 122 includes bug fixes and performance improvements for Web Inspector, Animations, CSS, CSS Color, CSS Aspect Ratio, JavaScript, WebAssembly, Web API, Media, WebRTC, and Accessibility.

The current Safari Technology Preview release is the built on the new Safari 14 update included in macOS Big Sur with support for Safari Web Extensions imported from other browsers, tab previews, password breach notifications, web authentication with Touch ID, and more.

The new Safari Technology Preview update is available for both macOS Catalina and macOS Big Sur, the newest version of the Mac operating system.

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.

Correct me if I am wrong. Is the current Safari 14 based on Release 109 in Safari Tech Preview?

I think so? There's so many Tech Preview releases comes out, it's kind of hard to correlate the Tech Preview to it's actual release outside of it's internal build number.

With STP 122 I can load pages with 3.8GB RAM without getting the message of using too much RAM and the scrolling is smoother no lags nor choppy.

The old one 121 was choppy when I was loading pages with 2.3-2.6 GB RAM of course the message was appearing too much ram is in use

The current version in Big Sur 11.2.3 is Safari 14.0.3 reloading pages which uses 2GB+ RAM.

I’ve been using the tech preview version since I got my M1 MBP because regular Safari runs like hot garbage on some sites like Reddit. Not sure what’s taking them so long to fix it.

Selection is lacking though and lack of uBlock Origin means pass.
For home use I would recommend getting Pihole on a raspberry pi or other stationary device.
No need to install adblockers on any device and it works really well.

Could also be used outside home if you create a VPN server (ex Wireguard) in your home network and connect to that in public hotspots etc.

Thanks for the suggestion but I've already looked into it and since PiHole is only a network layer blocker it isn't as granular nor as effective as uBlock Origin that works both at network and application layers. For example, it doesn't block YouTube ads while uBO does. Also, VPN to home isn't ideal since it limits download throughput to that of your outbound speed if on asymmetrical broadband. And, uBO is quick and easy to install in under a minute.

Quiet thread. Has anyone using 122 experienced or noticed anything new or different or better? Running it as my primary now, and haven't found anything at all.

It looks like the major bugs are kinda gone. Especially the RAM pop-up on several websites. I think they worked a bit under the hood of it.

You also have 1Blocker, Adguard...these are similar to uBlock Origin

Tried 1Blocker and it's rubbish in comparison. uBlock Origin seems more stable than Adguard which is my backup.
yeah, i used to love uBlock but...seems apple cut the sh** out of extensions, i had to find an alternative. Now i'm using 1blocker, but especially for "hide elements" on pages, also ads on youtube, which, doesn't work like Adguard though.

"Bug Fixes and Performance Improvements" should not be reported as news. Its like saying the sun will come up tomorrow. Its in every update release.

Actually, its better to use adblocker with PiHole. It complements it. For example it adds cosmetic filters, meaning that if it blocks an ad, it takes that space out of the website and not leave it blank looking ugly. It can also block things Pihole can't, like ads being served from the same domain.

And, uBO is quick and easy to install in under a minute.

The advantage of PiHole is that it blocks network wide devices. TVs, mobile phone apps, IoT, tablets, videogame consoles. It also blocks trackers. uBlock can only block within the browser.

Best is to use both. They work together like water and soap.

Running great for me as my daily browser. Only glitch I have found is that sometimes command–W won’t close a window. I have to hit command–T to open a second tab before it will work. No big deal.

I just realized that you can move the cursor to left side of safari to show the reading list and history sidebar/window
