Alright, I've updated the image for the Pi 4. Again, I don't have a Pi 4 to test it with but it "should" work. It still works on the Pi 3 after the updates so that's a good sign. You can download it from
here. I should note that due to the larger boot partition required by the Pi 4 and the extra updates, the image is quite a bit larger and needs at least a 4GB SD card.
Anyway, please report back to me if it works and I'll add a link to download it from the DC Live Downloads page.
