ISC DHCP 4.2.0a2 is now available for download.

This is the SECOND ALPHA of ISC DHCP 4.2.0, a feature release which
contains many new features, as well as a number of bug fixes.

There is a known flaw with failover recovery from 'potential conflict.'
In the event the failover servers disconnect and reconnect during the
recovery transition, the reconnecting servers will reach a stalemate
and fail to transition to normalcy.  This will be addressed in upcoming
releases through beta.

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 4.2.0a1

- When using 'ignore client-updates;', the FQDN returned to the client
  is no longer truncated to one octet.

- Cleaned up an unused hardware address variable in nak_lease().

- Manpage entries for the ia-pd and ia-prefix options were updated to
  reflect support for prefix delegation.

- Cleaned up some compiler warnings

- An optimization described in the failover protocol draft is now included,
  which permits a DHCP server operating in communications-interrupted state
  to 'rewind' a lease to the state most recently transmitted to its peer,
  greatly increasing a server's endurance in communications-interrupted.
  This is supported using a new 'rewind state' record on the dhcpd.leases
  entry for each lease.

- Fix the trace code which was broken by the changes to the DDNS code.
