It's a month since the release of dnsmasq-2.60. Despite the large
changeset which went into that release, very few problems have been
found with it. There is one regression in the DHCPv4 code that can cause
crashes with rare configurations, and a few problems have turned up with
the new DHCPv6 code.
Since the 2.60 release, I've continued to work on the new DHCPv6 code
and especially the router-advertisement code. The RA code has now
matured nicely and looks like a viable built-in replacement for the
various stand-alone RA daemons in the sort of systems dnsmasq runs on.
I'd like to get this code into wider use ASAP, so I'm starting the
process towards a 2.61 release.
There is one known possible problem, with the ra-names feature and Apple
OS X, so anyone who uses DHCPv4 and IPv6 on Macs with SLAAC addresses is
encouraged to enable ra-names, and check if clients get AAAA records in
the DNS.
Please test this release if you can.

Translators, please do your stuff. The changes are mainly in the man page.
I'm away for the next 10 days with intermittent net connectivity. I hope
that we'll be ready for a full release soon after I return.
Full 2.60 -> 2.61 changelog below.
Cheers,
Simon.
------------------------------------------------------------------------------
version 2.61
Re-write interface discovery code on *BSD to use
getifaddrs. This is more portable, more straightforward,
and allows us to find the prefix length for IPv6
addresses.
Add ra-names, ra-stateless and slaac keywords for DHCPv6.
Dnsmasq can now synthesise AAAA records for dual-stack
hosts which get IPv6 addresses via SLAAC. It is also now
possible to use SLAAC and stateless DHCPv6, and to
tell clients to use SLAAC addresses as well as DHCP ones.
Thanks to Dave Taht for help with this.
Add --dhcp-duid to allow DUID-EN uids to be used.
Explicitly send DHCPv6 replies to the correct port, instead
of relying on clients to send requests with the correct
source address, since at least one client in the wild gets
this wrong. Thanks to Conrda Kostecki for help tracking
this down.
Send a preference value of 255 in DHCPv6 replies when
--dhcp-authoritative is in effect. This tells clients not
to wait around for other DHCP servers.
Better logging of DHCPv6 options.
Add --host-record. Thanks to Rob Zwissler for the
suggestion.
Invoke the DHCP script with action "tftp" when a TFTP file
transfer completes. The size of the file, address to which
it was sent and complete pathname are supplied. Note that
version 2.60 introduced some script incompatibilties
associated with DHCPv6, and this is a further change. To
be safe, scripts should ignore unknown actions, and if
not IPv6-aware, should exit if the environment
variable DNSMASQ_IAID is set. The use-case for this is
to track netboot/install. Suggestion from Shantanu
Gadgil.
Update contrib/port-forward/dnsmasq-portforward to reflect
the above.
Set the environment variable DNSMASQ_LOG_DHCP when running
the script id --log-dhcp is in effect, so that script can
taylor their logging verbosity. Suggestion from Malte
Forkel.
Arrange that addresses specified with --listen-address
work even if there is no interface carrying the
address. This is chiefly useful for IPv4 loopback
addresses, where any address in 127.0.0.0/8 is a valid
loopback address, but normally only 127.0.0.1 appears on
the lo interface. Thanks to Mathieu Trudel-Lapierre for
the idea and initial patch.
Fix crash, introduced in 2.60, when a DHCPINFORM is
received from a network which has no valid dhcp-range.
Thanks to Stephane Glondu for the bug report.
Add a new DHCP lease time keyword, "deprecated" for
--dhcp-range. This is only valid for IPv6, and sets the
preffered lease time for both DHCP and RA to zero. The
effect is that clients can continue to use the address
for existing connections, but new connections will use
other addresses, if they exist. This makes hitless
renumbering at least possible.
Fix bug in address6_available() which caused DHCPv6 lease
aquistion to fail if more than one dhcp-range in use.
Provide RDNSS and DNSSL data in router advertisements,
using the settings provided for DHCP options
option6:domain-search and option6:dns-server.
Tweak logo/favicon.ico to add some transparency. Thanks to
SamLT for work on this.
