Key Highlights:

This is a small hotpatch designed to address a reported bug from the 22.12.4 release and updates Samba to the v4.17.12 security update:

EDIT UPDATE:

Known Issue: An issue was found after 22.12.4.1 was released that disrupts migrations from CORE to SCALE 22.12.4.1 due to how the /home directory is handled during the update process (NAS-124623). If you encountered this issue when attempting to migrate from TrueNAS CORE to SCALE 22.12.4.1, run the command mkdir /home in the TrueNAS CORE web interface shell and re-apply the upgrade.

Otherwise, users that intend to migrate from TrueNAS CORE to SCALE 22.12 (Bluefin) can directly migrate to the 22.12.4.2 hotfix release to avoid this issue.
