It is also interesting that at some point, quietly, the Arduino engineers have quietly switched from Eagle to Altium.

People may complain Eagle is not Free software, but at least it has a free-beer license available to view and edit the files for noncommercial use, and it runs perfectly on Linux and MacOS.

It is also pretty awful though. I can't blame them for switching. Especially for something with WiFi and USB 3. If be very surprised if Eagle is good enough for that.
