Good news for our trans friends:

The European Court of Justice on Thursday ruled that European Union nations must provide transgender citizens with identification documents reflecting their "lived gender" rather than their gender at birth.

To translate this for non-EU people, it's the equivalent of the US supreme court (the ECJ here) ruling that states (the EU Member States here) must respect people's gender choices.
