doesn't accidentally jump too far ahead due to faulty hardware or
batteries.
* A new setting SaveIntervalSec= has been added to systemd-timesyncd,
which may be used to automatically save the current system time to
disk in regular intervals. This is useful to maintain a roughly
monotonic clock even without RTC hardware and with some robustness
against abnormal system shutdown.
* .network files gained a new UplinkInterface in the [IPv6SendRA]
section, for automatically propagating DNS settings from other
interfaces.

* CAN support in systemd-networkd gained four new settings Loopback=,
OneShot=, PresumeAck=, ClassicDataLengthCode= for tweaking CAN
control modes. It gained a number of further settings for tweaking
CAN timing quanta.
* The [CAN] section in .network file gained new TimeQuantaNSec=,
PropagationSegment=, PhaseBufferSegment1=, PhaseBufferSegment2=,
SyncJumpWidth=, DataTimeQuantaNSec=, DataPropagationSegment=,
DataPhaseBufferSegment1=, DataPhaseBufferSegment2=, and
DataSyncJumpWidth= settings to control bit-timing processed by the
CAN interface.
* DHCPv4 client support in systemd-networkd learnt a new Label= option
for configuring the address label to apply to configure IPv4
addresses.
* The various systemd-networkd "ethtool" buffer settings now understand
* The various systemd-udevd "ethtool" buffer settings now understand
the special value "max" to configure the buffers to the maximum the
hardware supports.
* systemd-networkd's .link files may now configure a large variety of
* systemd-udevd's .link files may now configure a large variety of
NIC coalescing settings, plus more hardware offload settings.
* systemd-analyze verify gained support for a pair of new --image= +

section that allows to specify a WoL "SecureOn" password on hardware
that supports this.
* DHCPv6 Prefix Delegation gained new settings UplinkInterface= and
UseDelegatedPrefix= for configuring how to propagate delegated
prefixes between uplink and downlink interfaces.
* The [DHCPv4] section in .network file gained a new Use6RD= boolean
setting to control whether the DHCPv4 client request and process the
DHCP 6RD option.
* The [DHCPv6PrefixDelegation] section in .network file is renamed to
[DHCPPrefixDelegation], as now the prefix delegation is also supported
with DHCPv4 protocol by enabling the Use6RD= setting.
* The [DHCPPrefixDelegation] section in .network file gained a new
setting UplinkInterface= to specify the upstream interface.
* The [DHCPv6] section in .network file gained a new setting
UseDelegatedPrefix= to control whether the delegated prefixes will be
propagated to the downstream interfaces.
* The [IPv6AcceptRA] section of .network files now understands two new
settings UseGateway=/UseRoutePrefix= for explicitly configuring
whether to use the relevant fields from the IPv6 Router Advertisement
records.
* The [CAKE] section of .network files gained a new setting
AutoRateIngress= for controlling automatic capacity estimation for
CAKE.
* The ForceDHCPv6PDOtherInformation= setting in the [DHCPv6] section is
now deprecated. Please use the WithoutRA= and UseDelegatedPrefix=
settings in the [DHCPv6] section and the DHCPv6Client= setting in the
[IPv6AcceptRA] section to control when the DHCPv6 client is started
and how the delegated prefixes are handled by the DHCPv6 client.
* IPv6 tokens configured in .network files may now optionally take a
secret key (i.e. Token=prefixstable:…)
* The [CAKE] section of .network files gained various new settings
AutoRateIngress=, CompensationMode=, FlowIsolationMode=, NAT=,
MPUBytes=, PriorityQueueingPreset=, FirewallMark=, Wash=, SplitGSO=,
and UseRawPacketSize= for configuring CAKE.
* A new SuppressInterfaceGroup= setting has been added to the
[RoutingPolicyRule] section of .network files.
* The IPv6Token= section in the [Network] section is deprecated, and
the [IPv6AcceptRA] section gained the Token= setting for its
replacement. The [IPv6Prefix] section also gained the Token= setting.
The Token= setting gained 'eui64' mode to explicitly configure an
address with the EUI64 algorithm based on the interface MAC address.
The 'prefixstable' mode can now optionally take a secret key. The
Token= setting in the [DHCPPrefixDelegation] section now supports all
algorithms supported by the same settings in the other sections.
* The [RoutingPolicyRule] section of .network file gained a new
SuppressInterfaceGroup= setting.
* The IgnoreCarrierLoss= setting in the [Network] section of .network
files now accepts a duration to be specified, controlling how time to
wait before no longer ignoring carrier losses.
* The [DHCPServer] section of .network file gained a new Router= setting
to specify the router address.
* systemd-analyze verify gained a new switch --recursive-errors= which
controls whether to only fail on errors found in the specified units
or recursively any dependent units.
