-This snapshot does not fix a number of compile problems that have

 This snapshot is being released in the hopes that a fair number of
 DHCP sites will download it, try it out, and submit bug reports and
 critique the new manual pages.  Please do not hold back - the plan is
 to cut the first Beta release in about two weeks - at the beginning of
 December.

+		    CHANGES FROM THE JUNE SNAPSHOT
+
+- Support for NeXTstep 3.x and 4.x
+
+- Added man pages for dhcpd.leases, dhclient-script, dhclient.leases
+  and dhclient.conf.   Move general documentation of DHCP options into
+  a seperate man page which is referred to by the dhclient.conf and
+  dhcpd.conf man pages.
+
+- Updated README to answer some frequently asked questions.
+
+- Fixed a bug in command-line interface specification in dhclient - it
+  was formerly not possible to specify that only certain interfaces be
+  configured.
+
+- Do not leave client scripts lying around in /tmp after they've been
+  used unless the -D flag is specified.
+
+- Add a new, non-standard, not-guaranteed-to-stay-the-same system
+  configuration status message server which can be used to trigger the
+  client to recheck its address, e.g., after a laptop has been put to
+  sleep and then awakened (this has yet to be documented).
+
+- Fix handling of media selection in the REBOOT phase - previously the
+  media type would not be remembered, which could cause severe delays
+  in reacquiring an address if the default media type was wrong.
+
+- Allocate space for a NUL terminator on the end of client options -
+  this was previously overlooked, and could cause garbage characters
+  to be written to the temporary client script files.
+
+- Use mkstemp if it's available.
+
+- Supply network number and broadcast address to the client script so
+  that on systems that need these values, they don't need to be
+  computed with an awk script.
+
+- Keep a PID file for the client and the relay agent, and have the
+  relay agent background itself by default.
+
+- Add client script for bsd/os, fix many niggling bugs in existing
+  client scripts and add support for static routing tables to all bsd
+  scripts.
+
+- Add a -q option to the client, server and relay agent so that they
+  can be started from /etc/rc scripts without spewing a bunch of
+  garbage on the console.   By default, all three daemons still print
+  startup messages, since these are helpful in bug reporting.
+
+- Don't print anything to stderr or stdout after going into
+  background.
+
+- Fix bug where hostname keyword was not being recognized in
+  dhcpd.leases file, resulting in the loss of lease database entries.
+
+- Fix problem on some operating systems where zero-length ifreq
+  structures were being offset incorrectly when scanning the interface
+  list on startup.
+
+- Unless a BOOTP client requests it, never send more than 64 bytes of
+  options.
+
+- Don't ping static leases, since we don't have a lease structure on
+  the heap to work with later.
+
+- Fixed a compile problem on Solaris 2.6.
+
+- Support interface aliases on Solaris.
+
+- Print day and month with leading zero in lease files if less than
+  ten, for easier parsing by perl/sed/awk scripts.
+
+- Never make the lease database world writable, even if dhcpd is
+  invoked with a bogus umask.
+
+- Fix DHCPRELEASE handling (before, addressed would never be
+  released.)
+
+- If there is more than one lease for a particular client on a
+  particular network, find the lease the client is asking for so as to
+  avoid a cycle of NAKs.
+
+- If a BOOTP request is received from a particular client and that
+  client has previously received a DHCP address, make sure that we
+  still find a valid BOOTP lease so that we don't cycle through
+  addresses.
+
+- Remove server-identifier option from documentation, other than to
+  document that it has been deprecated.
+
+- Don't give up if we get an EINTR or EAGAIN while polling or
+  selecting - these return statuses can occur spuriously without
+  indicating a fatal problem.
+
+- Do not select for exceptions, since we don't handle them.   This was
+  causing massive CPU consumption on some systems.
 
+- When a DHCP client has been assigned a fixed address but had
+  previously had a lease, it will request the old leased address.   In
+  such an event, send a DHCPNAK so that it will discover its new
+  static binding.
