Earlier on the morning in today, Apple seeded the fourth beta of an upcoming macOS High Sierra to developers, and it was less than a week after releasing the third macOS High Sierra 10.13.1 beta and a month after releasing the new High Sierra operating system to the public.
At present, the fourth beta of macOS High Sierra 10.13.1 can be downloaded from the Apple Developer Center, or through the Software Update mechanism in the Mac App Store with the proper profile installed. In addition, the Public Beta of macOS High Sierra 10.3.1 has been released to developers.

The major upgrades in macOS High Sierra 10.13.1 seems to focus on bug fixes, performance improvements, security enhancements, and other under-the-hood changes, which include fixing a serious vulnerability in the WPA2 Wi-Fi standard that protects many modern Wi-Fi networks.
