It is with great regret that the organising committee of DIAGRAMS 2020 announce that the conference, planned for 24-28th August, will not take place face-to-face in Tallinn, Estonia. Authors of accepted papers, posters and abstracts will be invited to upload a video of their work, and their videos will be available through the conference website http://www.diagrams-conference.org/2020/ to all from August 24th. In order to allow the organising committee to focus on the main scientific conference, the satellite events have been cancelled entirely. These events are the Tutorials, the co-located Workshop, the Graduate Symposium, and the Keynote contributions.
