fex (20200419-1) unstable; urgency=medium

  F*EX listening socket moved from xinetd to systemd.socket with matching
  service. Auto-migration is not performed, but defaults should migrate
  smoothly.

  If you want to migrate manual configs, remove /etc/xinetd.d/fex and run:
  systemctl enable fex.socket
  systemctl start fex.socket
