Registration rates

It is our deepest regret to announce that, due to the rapidly deteriorating situation all over Europe, the in-person part of the conference needs to be cancelled. The conference will still take place as a virtual-only event. All physical registrations will be converted to their virtual equivalent rate, and refunds will follow soon.

Due to the updated conference format, the workshop has also been cancelled.
