Apple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced in March of 2016. Apple designed the Safari Technology Preview to test features that may be introduced into future release versions of Safari.
Safari Technology Preview release 39 includes fixes and improvements for Beacon API, Directory Upload, Fetch API, Input Events, JavaScript, WebAssembly, WebRTC, Web Inspector, and Media. With Safari 11 now available to developers through the macOS High Sierra beta, Apple is providing two versions of Safari Technology Preview, one for macOS Sierra users and one for those using macOS High Sierra.
Safari Technology Preview users might want to hold off on downloading Safari Technology Preview 39 as the new version appears to be crashing at launch and not working properly.
The Safari Technology Preview update is available through the Software Update mechanism in the Mac App Store 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.
Update: The Safari Technology Preview 39 release has been pulled by Apple and is no longer available for download.

(Actually did crash on install.)
Edit: I wrote crash on install but this may have been on some kind of auto start during install. I’m not sure, as I wasn’t paying attention, just noticed that the crash report dialogue box popped up.
Also, my Mac mini 2012 is running the latest High Sierra Public Beta installed on 9/1 or 9/2 and, this, I’m running STP for High Sierra.
Edit: Thanks @Weaselboy :) for updating it.
