    - Remove the patch which enforces usage of iptables instead of
      nftables:
      * 0001-firewall-backend-Switch-default-backend-to-iptables.patch
    - Add firewalld zone for the docker0 interface. This is the
      workaround for lack of nftables support in docker. Without that
      additional zone, containers have no Internet connectivity.
      (rhbz#1817022)
    - Update to 0.9.1:
      * Bugfixes:
        * docs(firewall-cmd): clarify lockdown whitelist command paths
        * fix(dbus): getActivePolicies shouldn't return a policy if a zone is not active
        * fix(policy): zone interface/source changes should affect all using zone
