Unraid OS version 6.12.3-rc3 available

The 6.12.3-rc3 release is a bug fix release that we'd like feedback on before releasing it as 6.12.3.

This thread is perfect for quick questions or comments, but if you suspect there will be back and forth for your specific issue, please start a new topic. Be sure to include your diagnostics.zip.

Upgrade steps for this release

1. As always, prior to upgrading, create a backup of your USB flash device:  "Main/Flash/Flash Device Settings" - click "Flash Backup".
2. Update all of your plugins. This is critical for the NVIDIA and Realtek plugins in particular.
3. If the system is currently running 6.12.0 - 6.12.2, we're going to suggest that you stop the array at this point. If it gets stuck on "Retry unmounting shares", open a web terminal and type:

   umount /var/lib/docker

   The array should now stop successfully (This issue is resolved with this release)

4. Go to Tools -> Update OS, change the Branch to "Next". If the update doesn't show, click "Check for Updates"
5. Wait for the update to download and install
6. If you have any plugins that install drivers (NVIDIA, Realtek, etc), wait for the notification that the new version of the driver has been downloaded. 
7. Reboot

Networking

This release has fixes for networking, particularly as it relates to IPv6. A side effect is that this will resolve an issue where the webgui won't load in certain instances. 

Note: If you have code in your go script to disable IPv6, remove that and disable it via the Settings -> Network Settings page instead. Disabling IPv6 by manually running commands will cause conflicts.

Docker

This release resolves an issue where Docker doesn't properly stop when the array stops, which can result in an unclean shutdown. 

Known Issues

Please review the known issues for 6.12: https://docs.unraid.net/unraid-os/release-notes/6.12.0#known-issues 

If Docker containers have issues starting after a while, and you are running Plex, go to your Plex Docker container settings, switch to advanced view, and add this to the Extra Params
