high frequency messages moved to a deeper debugging symbol.
- The CLTT parameter in failover is now only updated by client activity,
and not by failover binding updates (taking on the peer's CLTT).
- Failover BNDUPD messages are now discarded if they conflict with an
update that has been trasnmitted, but not acknowledged.

not be applied to clients addressed within that network was repaired.
- When configuring a "subnet {}" or "subnet6 {}" without an explicit
shared-network enclosing it, the DHCP software would synthesize a
shared-network to contain the subnet. However, all configuration
parameters within the subnet more intuitively belong "to any client
on that interface", or rather the synthesized shared-network. So,
when a shared-network is synthesized, it is used to contain the
configuration present inside the subnet {} clause. This means that
the configuration will be valid for all clients on that network, not
just those addressed out of the stated subnet. If you intended the
opposite, the workaround is to explicitly configure an empty
shared-network.
- A bug was fixed where Information-Request processing was not sourcing
configured option values.
- A warning was added since the DHCPv6 processing software does not yet
support class statements.

- Use lease referencers to maintain reference count on the lease structure.
- Log an error if you encounter a lease with no transmit-state.

released in bursts after single fsync() events when the upper limit is
reached or if the receiving sockets go dry. The practical upshot is
that fsync-coupled server performance is now multiplicitively increased.
The default delayed ack limit is 28. Thanks entirely to a patch from

version 3.0.x failover server, a warning that the failover wire protocol
is incompatible is printed. [ISC-Bugs #17129]
- The failover server no longer issues a floating point error if it encounters
a previously undefined option code. [ISC-Bugs #17129]
broke a lot of legacy site local configurations. The new code in place will
track site local space minimum option codes and logs a warning to encourage
updates and exploration of site local code migration problems. Option
codes less than 128 in site local spaces remain inaccessible.
[ISC-Bugs #17203]
- A possible relay agent option bug was repaired where random server
initialization state may have been used to signal the relay agent
information options sub-option code for the 'END' of the option space.
