Apple today seeded the fourth beta of an upcoming macOS High Sierra update to developers, 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.

The fourth macOS High Sierra 10.13.1 beta can be downloaded from the Apple Developer Center or through the Software Update mechanism in the Mac App Store with the proper profile installed.

macOS High Sierra 10.13.1 focuses primarily on bug fixes, performance improvements, security enhancements, and other under-the-hood changes.

It includes a fix for a serious vulnerability in the WPA2 Wi-Fi standard that protects many modern Wi-Fi networks. Using a key reinstallation attack or "KRACK," attackers can exploit weaknesses in the WPA2 protocol to decrypt network traffic to sniff out sensitive information. This attack is not possible with the patch in macOS 10.13.1.

The update also introduces a range of new Unicode 10 emoji like crazy face, pie, pretzel, t-rex, vampire, exploding head, face vomiting, shushing face, love you gesture, brain, scarf, zebra, giraffe, fortune cookie, pie, hedgehog, and more. The new emoji are also available in iOS 11.1 and watchOS 4.1.

macOS High Sierra is a major update that introduces APFS, a new more modern file system, HEIF and HEVC photo and video encoding improvements for smaller file sizes without compromising quality, Metal 2, and several new features for Safari, like autoplay blocking for videos and Intelligent Tracking Prevention to better protect user privacy.

Update: There's a new public beta of macOS High Sierra 10.3.1 available for public beta testers.

Been having a major issue that I reported directly to a senior leader of the software team. Whenever I wake up my MBP from sleep (with password authenticated access enabled), it jumps immediately to the desktop. It happens so quickly you can't even put a password in if you tried; it's bypassed completely. Hopefully that's been patched here.
 
Did the public beta 3 ever come out?
There is a difference between Developer-Beta and Public beta. The first beta version usually is only supplied to the Developers and therefore the DB-count is one higher than the public one.

They are currently on the same count and are exactly the same.

I don't know why, but there seems to have been a new tvOS as well. It offered itself Sunday. I noticed that my streaming slowed down and stopped. Guess what, the Network pane had to be redone. There and on the iPad that had just updated. A hassle, but I take this as a sign I'm no longer vulnerable to KRACK.
 
It was a full install. It WILL NOT show up as an update. You need to reinstall the beta profile and then it will pop up in the app store as a full install.

I think I may have typed this 100 times.

Showed up as an update for me, in the updates tab of the App Store.......

Any word on RAID updates for APFS? Hoping that bootable RAID 0 APFS will make a return at some point.
 
Did the public beta 3 ever come out?
Yes, the Public Beta 3 came out the same way as the Dev Beta 3. You had to reinstall your beta profile, then the new build would download. I believe it showed up late last Monday or early last Tuesday. Like mentioned by others, the same as the developer beta, it was not available as an update.
