German passports will be issued with three possible sex indications: M, F, or X. That is male, female and intersex classifications, including for newborn babies.

Well done Germany. It is long overdue that states realize that shoving people into binary categories fails to work for the diverse species of human beings.

Australia already allowed for this, but there were problems from the machine-reading of the machine-readable sections. New Zealand also allows for X IIRC.
