Fully downloaded and being installed on my devices. Excited to see what is tweaked.
 
I'm getting a big fat error every time I try to download the update. Reinstalled the profile and restarted my MBP, issue persists.

For people with issues updating, the Feedback app shows this as a known issue for beta one:
  • If you updated to macOS Big Sur 11 beta from a previous version of macOS, Software Update might show "Unable to check for updates - Failed to download the documentation for the minor update. Please try again later". (63158434)
    Workaround:
    1. Start up from macOS Recovery.
    2. If your data volume is encrypted, use Disk Utility to mount it.
    3. In Terminal type rm -rf "/Volumes/Macintosh HD - Data/private/var/folders/zz/zyxvpxvq6csfxvn_n00000y800007k".
    4. Restart your Mac.
 
We want to see what changes were made (if any) since the Beta 1.

Follow the herd, or maybe you could get updates on here? Just a thought.

Absolutely no chance.
 
Looks more like an iOS message.
Don't ever recall seeing a "Preparing" message for MacOS updates.

My machine went through the whole download, preparing update, I rebooted, but it didn't update! It's now downloading the update again!

I have a feeling this beta cycle is going to be more "fun" than usual.

I saw this as well in the notes but unfortunately this did not fix it. Initially the Software Update screen looked normal upon restart but then it said no new updates available. So I closed out and opened again, and it went back to saying "Unable to check for updates"
 
I've not had any issues with messages not closing, to be honest it's been pretty stable

Can't see what's different in this release though, and the build number is only one higher - never understood what the letters mean after the build number though, if anybody knows please help me sleep at night...

Didn't work.
 
You forgot one of the biggest under the hood change.

The locked state of Big Sur.

Are you going to come to every Big Sur thread to try and scare people about the 'locked' state? I develop software all day long and have been doing my daily development on Big Sur without issue. Brew, terraform, java, golang, etc... all work just fine. If you're upset that Big Sur prevents your pet kernel extension by default, then unlock the SIP and move on. Repeating it's locked over and over is trying to make an issue out of something that is a non-issue for the very large majority, and an improvement security wise.
