The major change here is that Ubuntu 20.04 moves the default root from /var/lib/tftpboot to /srv/tftp. That matches what Debian does. The data files are changed so that only Ubuntu 16.04 and 18.04 have overrides. This technically breaks versions in between, but those aren't supported.
Support Ubuntu 20.04
