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 149 includes bug fixes and performance improvements for Web Inspector, Media, CSS, CSS Container Queries, Rendering, JavaScript, Screen Sharing, Web Animations, WebAuthn, Navigation Preload, Web API, and Security.

The current Safari Technology Preview release is built on the Safari 16 update and it includes support for feature coming in macOS Ventura such as Live Text, Passkeys, Web Extension improvements, and more.

The new build of Safari Technology Preview is compatible with machines running macOS 13 Ventura, unlike prior versions of Safari Technology Preview, but it no longer works with macOS Big Sur.

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.

Why would anyone want to install Safari Technology Preview on a Mac running macOS 13 updated beta 3? You already running Safari 16.0 beta build, so why add the risk of additional Safari issues cause by this preview install?

Safari on B3 is seemingly ahead of TP?

Safari 16.0, WebKit 18614.1.19.1.5
Safari TP 16.0, WebKit 18614.1.17.3

EDIT: Oh, that's Release 148. 149 isn't showing up for me.

No issues here pal. I always run STP. It didn't run on Ventura beta 1 or 2, but working now. For the record, the STP page says version 148 not 149 and is working fine. Maybe 149 got pulled?and what risk? If it doesn't work, you don't use it.

Another interesting fact, remember when Google was bragging about being faster than Safari? Nope, not even close. Maybe they ran a special edition or maybe they ran under windows or something. On my M1 MBP, Safari and STP blow away all other browsers. Firefox totally sucks, must not have been updated or something, maybe it is using Rosetta. Chrome and Brave are at lease respectable (albeit way slower than safari)

This build is postponed due to a bug:

NOTE: Safari Technology Preview release 149 was removed to address an issue. This note will remain until an updated release is available.
Safari Technology Preview Release 149 is temporarily unavailable for macOS Monterey 12.3 or later and macOS Ventura beta. Updates to Safari Technology Preview are no longer available for macOS Big Sur. If you already have Safari Technology Preview installed, you can update in the Software Update pane of System Preferences on macOS Monterey, or System Settings under General → Software Update on macOS Ventura.

If your part of seeding of Safari for older OSs I seen several times a Safari version that cause both Safari's to not work. Removing and reinstalling Safari is not easy once it causes that type of failure.

As for discussing Safari speeds ever since Google said Crome was so fast, Safari since 12.4 betas has had caching very improved. see this May post.
