---------------
netplan.io (0.96-0ubuntu0.18.10.2) cosmic; urgency=medium

  * d/p/0001-Partially-revert-the-change-for-enabling-systemd-net.patch:
    Partially revert changes to networkd jobs ordering: leave systemd-networkd
    enabled in multi-user.target instead of network-online.target, as in some
    minimal setups there might be no job requiring network-online.target,
    whereas the natural target to reach for booting is multi-user.target.
    (LP: #1821867)

netplan.io (0.96-0ubuntu0.18.10.1) cosmic; urgency=medium

Title:
  Cannot enable IPv6 privacy extensions

Status in netplan:
  Fix Released
Status in netplan.io package in Ubuntu:
  Fix Released
Status in netplan.io source package in Bionic:
  Fix Committed
Status in netplan.io source package in Cosmic:
  Fix Released

Bug description:
  [Impact]
  Ubuntu users concerns with privacy of their IP addresses over IPv6.

  [Test case]
  1) Configure netplan with IPv6 privacy enabled:

  network:
    version: 2
    ethernets:
      eth0:
        dhcp6: true
        ipv6-privacy: true

  2) Run 'netplan apply'
  3) Run 'ip -6 addr'
  4) Verify that additional temporary addresses are added by the kernel.

  [Regression Potential]
  Minimal. This enables or disables the setting for IPv6 privacy addresses on an per-interface basis, and defaults remain unchanged.

  ---

  
  Summary:

  netplan contains no configuration entry that allows one to enable IPv6
  Privacy Extensions (RFC 4941) when autogenerated (DHCPv6 stateless,
  SLAAC) addressing is used.

  This should map to the IPv6PrivacyExtensions entry for systemd-
  networkd (man systemd.network, [Network] section), and the
  ipv6.ip6-privacy entry for NetworkManager
  (https://developer.gnome.org/NetworkManager/stable/settings-
  ipv6.html).
