We planned the 2021 edition of the conference to be a mixed in-person and online event.
We are working to understand if this is still allowed by the pandemic situation. The rule to participate in indoor activities in Italy, effective August 6th, is that a "green pass" (electronic certificate of full vaccination) is mandatory. Indoor activities include restaurants, cinemas, concerts and conferences. It looks like, effective September 1st, a "green pass" will also be necessary to travel by plane or train, but this is still under debate.
Please check this page for updates about the possibility of in-person attendance and upcoming regulations on this page. And please check with your country's travelling regulations before making plans to travel to Italy.
