			      Release Notes

			      NEW FEATURES

Version 4.1-ESV-R9rc1 is a maintenance release of an extended support version
(ESV) release.  ESVs are intended for users who have longer upgrade
constraints.  Please see our web page
http://www.isc.org/downloads/extended-support
for more information on ESVs.

ISC DHCP 4.1.x includes several new DHCPv6 features that were not included
in DHCP 4.0.x.  These include:

- Support for the rapid-commit option on the client side

- Prefix Delegation support

- IA_TA address support

- A basic DHCPv6 relay agent

- Basic and partial DHCPv6 leasequery support

There are a number of DHCPv6 limitations and features missing in this
release, which will be addressed in the future:

- Only Solaris, Linux, FreeBSD, NetBSD, and OpenBSD are supported.

- Only a single address is supported per IA.

- DHCPv6 includes human-readable text in status code messages. These
  should be configurable, and probably localized via gettext() or the
  like.

- The "host-identifier" option is limited to a simple token.

- The client and server can only operate DHCPv4 or DHCPv6 at a time,
  not both.  To use both protocols simultaneously, two instances of the
  relevant daemon are required, one with the '-6' command line option.

For information on how to install, configure and run this software, as
well as how to find documentation and report bugs, please consult the
README file.

ISC DHCP uses standard GNU configure for installation. Please review the
output of "./configure --help" to see what options are available.

The system has only been tested on Linux, FreeBSD, and Solaris, and may not
work on other platforms. Please report any problems and suggested fixes to
<dhcp-users@isc.org>.

ISC DHCP is open source software maintained by Internet Systems
Consortium.  This product includes cryptographic software written
by Eric Young (eay@cryptsoft.com).

  [ISC-Bugs #33510] [ISC-Bugs #33511]

  [ISC-Bugs #26303]

- Remove a variable when it isn't being used due to #ifdefs to avoid
  a compiler warning on Solaris using GCC.
  [ISC-Bugs #33032]

  Thanks to Paolo Pellegrino for finding the issue and a suggestion
  for the patch.
  [ISC-Bugs #33351]

- Added a sleep call after killing the old client to allow time
  for the sockets to be cleaned.  This should allow the -r option
  to work more consistently.
  [ISC-Bugs #18175]

  the release tarballs. To generate this documentation, please use

  of a client on a single machine to work properly.  Previously only
  one client would receive the packets.  Thanks to Jiri Popelka at Red Hat
  for the bug report and a potential patch.
  [ISC-Bugs #34784]

- Enhance the DHCPv6 server logging to include the addresses that are assigned
  to the clients.  This can be enabled by defining LOG_V6_ADDRESSES in site.h.
