Yeah, too much waring as if historry hadn't warned us enough.
But the PCB text is also rotated, so if they changed the silkscreen they could as well have corrected the spelling, couldn't they ?
Look at the orientation of the AHWSA_MB label.
By the way putting a sticker over the PCB version number is a bad idea.
The white rectangle surrounding the warning sticker is also missing in the second PCB.
