Windows 10: Anyone know the purpose of the Preview update KB4568831 released the 31st is?

I just got this update on two systems. It lists MANY fixes so why is it being released as a "Preview" and what does it mean for future updates.?

KB4568831 not installing

I am presently at version 20H2 OS build 19042.388. KB4568831 is failling to install, it just loops from installing to downloading back to downloading. The following is logger in event viewer

Error Installation Failure: Windows failed to install the following update with error 0x8024200D: 2020-07 Cumulative Update Preview for Windows 10 Version 20H2 for x64-based Systems (KB4568831).

I have ran SFC and DISM with no errors. Deleted files in c:windows\softwaredistribution\downloads with no help. Any ideas

Windows 10 Insider Preview, error installing Cumulative Update Preview for Windows 10 Version 20H2 for x64-based Systems (KB 4568831).

I have 2 Windows 10 machines on insider preview. One is running fine, and recently installed Cumulative Update Preview for Windows 10 Version 20H2 for x64-based Systems (KB4568831).

The other machine seems to install it, reboots, spins after reboot for quite some time (with the message updates are being installed etc.). After some time, it displays a message that "windows update we couldn't complete the updates undoing changes". Once
it is done and I log in, I see that the same update is offered again. Looking in the logs I see the below message:

"

Installation Failure: Windows failed to install the following update with error 0x800F0920: 2020-07 Cumulative Update Preview for Windows 10 Version 20H2 for x64-based Systems (KB4568831).

"

Is anyone else seeing this as well?
