An update from the KiCon website:
After a successful first year of KiCon in 2019, we decided to change venues. We were very excited to hold the conference at CERN, a major contributor to the KiCad project. However, Coronavirus / COVID-19 changed a lot of plans, including ours.
We will be hosting a short program on October 3rd. The key focus will be a developer session, where members of the community can hear about the changes to the upcoming version 6 software, and ask questions directly to the developers. Further planning details to follow.
