configured once. dhcpd will now fail to load config files that specify
multiple identifiers (previous versions would silently over-ride the
value with the later configured value). [ISC-Bugs #15533]

- 'ignore client-updates;' now has behaviour that is different from
'deny client-updates;'. The client's request is not truly ignored,
rather it is encouraged. Should this value be configured, the server
updates DNS as though client-updates were set to 'deny'. That is, it
enters into DNS whatever it is configured to do already, provided it is
configured to. Then it sends a response to the client that lets the
client believe it is performing client updates (which it will), probably
for a different name. In essence, this lets the client do as it will,
ignoring this aspect of their request. [ISC-Bugs #16185]

- In those cases where the DHCP software manufactures an IP header (to
transmit via bpf, lpf, etc), the IP TTL the software selects has been
increased from 16 to 128. This is intended to match Microsoft Windows

- A new DDNS related server option, update-conflict-detection, has been
added. If this option is enabled, dhcpd will perform normal DHCID
conflict resolution (the default). If this option is disabled, it will
instead trust the assigned name implicitly (removing any other bindings
on that name). This option has not been made available in dhclient.

- If the dhclient were to receive a DHCPNAK while it was in the RENEW
state (and consequently, had an active, 'bound' address and related
configuration options), it would fail to 'tear down' this information

INIT state. [ISC-Bugs #16035]

- Failover pairs now implement 'MAC Affinity' on leases moving from the
active to free states. Leases that belonged to the failover secondary

If lease rebalancing must move leases, it tries first to move leases
that belong to the peer in need.
- The server no longer sends POOLREQ messages unless the pool is severely
misbalanced in the peer's favor (see 'man dhcpd.conf' for more details).
- Pool rebalance events no longer happen upon successfully allocating a
lease. Instead, they happen on a schedule. See 'man dhcpd.conf' for the

Add translated Japanese man pages to the doc/ directory.
The directory structure for translated manual pages should be :
doc/<locale>.<encoding>
This nomenclature is used by several other open-source documentation
projects. These manual pages are current as of DHCP 3.0.1rc8 but they
are not complete. These man pages only cover the client.
We should add $Id$ tags to the english language documents, so we can
easily see what version of the English document this Japanese document
is current with.
