Until today, Germany had a long list of "high risk" countries, which required the completion of a passenger locator. That list is now empty, although they may put countries back on it as the situation evolves.
I discovered this change when preparing to fill in the form for arriving on Sunday from Austria. Last night, it was still required, but I wasn't able to do it until today, as it could only be done three days in advance. Today, it ceased to be required for my journey,
so I dropped lucky.
