Conference COVID-19 Information — July 31 2021 update

FSE 2021 will be fully online

Unfortunately, the physical component of the ACM Joint European Software Engineering Conference and Symposium on the Foundations of Software Engineering (ESEC/FSE) ’21 will be canceled. Back in 2017, when we first bid for ESEC/FSE ’21, we planned for an all-physical event to take place in sunny Athens, Greece: a city renowned for its ancient history, cultural sights, and modern attractions. The ghastly COVID-19 pandemic cast doubts on our plans, but then the prospect of vaccinations brought the hope that a wall of immunity would allow us to host many of our community’s colleagues in Athens for face-to-face discussions and interactions over lively social events.

This was not meant to be. The COVID-19 delta variant, the associated rising cases and transmission rate, renewed travel restrictions, and a very low number of physical registrations made the planned physical event untenable for safety, academic, and financial reasons. Our apologies to those of you who planned and registered to attend; please contact the conference registration office at info@easyconferences.eu to arrange for the refund of the physical event registration fee.

Needless to say that the virtual component of ESEC/FSE ’21 will take place as originally planned. We’re looking forward to the online meeting of the hundreds of registered conference attendants, the video presentations, and all the interactions over the Clowdr platform and social media.

Kind regards,

Diomidis Spinellis and Georgios Gousios
ESEC/FSE 2021 General Chairs
