This may be low priority because it doesn't seem to be used for anything (yet), but I have noticed that the new uuid database field is not assigned a uuid for new serial numbers, although the update_156() routine took care to assign them for existing entries.
I was able to address it on the database side with:
ALTER TABLE {$prefix}serial_numbers CHANGE uuid uuid DEFAULT (UUID());UPDATE {$prefix}serial_numbers SET uuid = UUID() WHERE uuid IS NULL;
