7285af3087 - DDNS updates state information are now stored in 'binding scopes' that 
follow the leases through their lifecycles.  This enables DDNS teardowns
  on leases that are assigned and expired inbetween a server restart (the
  state is recovered from dhcpd.leases).  Arbitrary user-specified binding
  scopes ('set var = "value";') are not yet supported.

98bd7ca099 DHCPv6 branch merged to HEAD. 2007-05-08 23:05:22 +00:00

6708d944e1 - Some default hash table sizes were tweaked, some upwards, some downwards. 
3.1.0a1's tables resulted in a reduction in default server memory use.
  The new selected values provide more of a zero sum (increasing the size
  of tables likely to be populated, decreasing the size of tables unlikely).

- Lease structures appear in three spearate hashes: by IP address, by UID,
  and by hardware address.  One type of table was used for all three, and
  improvements to IP address hashing were applied to all three (so UID and
  hardware addresses were treated like 4-byte integers).  There are now two
  types of tables, and the uid/hw hashes use functions more appropriate
  to their needs.

- The max-lease-misbalance percentage no longer causes scheduled rebalance
  runs to be skipped: it still governs the schedule, but every scheduled
  run will attempt balance.

encountering non-retryable errors during writing) lease file should
  no longer result in an infinite recursion. [ISC-Bugs #16265]

5e86441636 - A new common (server or client) option, 'db-time-format local;', has 
been added which prints the local time in /var/db/dhcpd.leases rather
  than UTC.  Thanks to a patch from Ken Lalonde. [ISC-Bugs #2678]
