The only thing I haven't got is how to uninstall? I still have some artifacts in my Trash, which can't be removed during a permission problem.

Is this a multilingual application? If YES, I will try it. If NO, I continue to use Safari.

Safari Technology Works nicely. Please note that if you are a CleanMyMac user, you can no longer uninstall this application from CleanMyMac.

The description at the top of the MacUpdate page says this is also available for MacOS Sierra (10.12) but if you go to Apple's website it only provides links for 10.13 and 10.14. The download link on MacUpdate for 10.12 is for release 49 and it hasn't been updated in pretty much a year now.

And now we're at v73! Again, until Apple get their lagging butts in gear, it is HIGHLY recommended to use Safari Technology Preview and NOT regular Safari due to a published exploit present in ALL of version 12.0.x. These latest betas have solved the exploit. Why Apple hasn't formally updated Safari is beyond comprehension. I'm starting to think of the word 'irresponsible' at this point.

Safari Technology Preview is now at v72 (aka compiled Safari v12.1 beta, WebKit 14607.1.17.1). It is highly recommended over regular Safari v12.0.2 as it includes a critical security hole patch.

IMPORTANT! Release 71 (Safari 12.1, WebKit 14607.1.15) is the current version of Safari Technology Preview as of December 5, 2018. This version is particularly important because all previous versions of Safari 12 (up through 12.0.2) have a vulnerability currently called "WebKit-RegEx-Exploit", for which a PoC, Proof of Concept, has been published. IOW: If you demand maximum Safari security, you MUST upgrade to this current version of Safari/WebKit. More about the exploit is published here: https://www.bleepingcomputer.com/news/security/webkit-vulnerability-affects-latest-versions-of-apple-safari/ The page providing the most current Safari Technology Preview is: https://developer.apple.com/safari/download/

I guess MacUpdate no longer Updates Mac Apps? The update for this has been out for days now.

This latest Version has lost the Keyboard Commands. Didn't remember the Previous Session. Pages take forever to Open. This is as bad as MS Office 2016.

Is anyone else using this Newest Version, Safari 11.1, WebKit 12605.1.2, from 3 Days ago? It barely functions in Sierra. I'm thinking it might be built for High Sierra(?)

There are a number of unacceptable bugs in 11.1 and I 'd advise skipping it until the next version. Unfortunately my STP was updated automatically and there's no version list to go back to. In the meantime I've started using Safari again.

@ Fyreflye

Me too. I would think apps that functions as badly as this version, would be patched pretty quickly. How can someone "Test" it if it only barely works?
