ISC DHCP 4.0.0rc1 is now available for download.  4.0.0 represents a
feature release, containing primarly DHCPv6 server and client
implementations.

This is the first release candidate of 4.0.0, which means we now
expect the software to be correct, stable, and ready for final
release.

A list of the changes in this release has been appended to the end
of this message.  For a complete list of changes from any previous
release, please consult the RELNOTES file within the source
distribution, or on our website:

			Changes since 4.0.0b3

- The reverse dns name for PTR updates on IPv6 addresses has been fixed to
  use ip6.arpa. rather than default to in-addr.arpa and require user
  configuration.

- dhc6_lease_destroy() and dhc6_ia_destroy() now set lease and IA pointers
  to NULL after freeing, to prevent subsequent accesses to freed memory.

- The DHCPv6 server would not send the preference option unless the
  client requested it, via the ORO. This has been fixed, so the DHCPv6
  server will always send the preference value if it is configured.

- When addresses were passed as hints to the server in an IA, they were
  incorrectly handled, sometimes being treated as an error. Now the
  server will treat these as hints and ignore them if it cannot supply
  a requested address.

- If the client had multiple addresses, and one expired (was not renewed
  by the server), the client would continue to attempt to renew the same
  old address over and over.  Now, the client will omit any expired
  addresses from future Confirm, Renew, or Rebind messages.

- dhclient -6 will now select renew/rebind timers based upon the longest
  address expiration time rather than the shortest expiration time, in
  order to avoid cascading renewals in the event a server elects not to
  extend one of multiple IAADDR leases.

- The server now limits clients that request multiple addresses to one
  address per IA by default, which can be adjusted through the
  "limit-addrs-per-ia" configuration option.

- The DHCPv6 client now issues fresh transaction IDs on Renew and Rebind
  message exchanges, rather than using the most recent ID.

- The DHCPv6 server now replies to Information-Request messages.

- A bug was fixed in the dhclient-script for BSDs to correctly carry error
  codes through some conditions.

- The parsing of some options in the dhclient lease file, in particular
  the success DHCPv6 status-code, was fixed.

- A bug was fixed that caused the DHCPv6 ORO option to be corrupted with
  seemingly random values.

- A reference overleak in DHCPv6 shared network processing was repaired.

- ./configure now autodetects local database locations rather than trying
  to put dhcpd.leases and dhclient.leases in /usr/local/var/db, which no
  one ever has.

- Regression fix for bug where server advertised a IPv6 address in
  response to a SOLICIT but would not return the address in response
  to a REQUEST.

- A bug was fixed where the DHCPv6 server puts the NoAddrsAvail status
  code in the IA_NA was fixed.  The status code now appears in the root
  level.
