I multiple boot my system with stable Windows 19041.450 and several Windows Insiders builds. Approximately a week ago, I was in one of the Insider builds (sorry I do not recall which one, could have been the Slow Ring), and when I did a check for updates (Windows Updates) there was a Firmware update already installed awaiting a Restart. It was BIOS version 1.0.23. I was currently running 1.0.22. This is the first time I can recall a Dell BIOS update coming thru WHQL MS Windows Update. I had little choice but to let it proceed. It restarted and updated fine, and all indications are I'm on 1.0.23. My issue is I cannot find anything, no announcement, no documentation, nothing on the Dell site or anywhere else. I have no idea what was changed.

Does anyone have any ideas where I can look? I'm a little concerned this 1.0.23 may be a beta bios, and I don't know it.

Any help will be appreciated.  Thanks.
