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.

address pools without having to constantly reconfigure the server. Please

active to free states. Leases that belonged to the failover secondary
are moved to BACKUP state rather than FREE upon exiting EXPIRED state.
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
min-balance and max-balance statements for more information.
