Seems like Safari Technology Preview has been in development for a long time.

Wow, since 2016 - 8 years.

When will it be finished and become the next Safari?
Safari takes improvements from Technology Preview all the time. It isn’t a separate product, instead the results of the preview are implemented in Safari every now and then.

Finally working again with the latest macOS Betas.

But still the same version 18.0 with just a higher build number.

Isn't TP normally not a newer version? There is a Beta of Safari 18 for Sonoma and Ventura so the TP should be something newer. But maybe this changes later. I wasn't on macOS beta for a while before Sequoia.

The first DB doesn't even had a launch-able version. And in DB3 it was unusable since release of this version.


Edit: Also feels snappier than standard Safari. 🙃
