Did you guys not read the title of the document?
I'll copy it hear to help you out:
Issuing body enhancements
Factsheet 1 of 4 - Identity Security Amendments – 1 November 2016
These changes only apply if you have recently had surgery to 'enhance ' your body.
It mainly only effects cabin crew but I have noticed the odd pilot become suddenly more enhanced after a holiday in Thailand. For most of us it's business as usual.
