--------------------------------------------------------------------------
            Fix failure to compile on Debian/kFreeBSD. Thanks to
            Axel Beckert and Petr Salinger.

            Fix code to avoid scary strict-aliasing warnings
            generated by gcc 4.4.

            Added FAQ entry warning about DHCP failures with Vista
            when firewalls block 255.255.255.255.

            Fixed bug which caused bad things to happen if a
            resolv.conf file which exists is subsequently removed.
            Thanks to Nikolai Saoukh for the patch.

            Rationalised the DHCP tag system. Every configuration item
            which can set a tag does so by adding "set:<tag>" and
            every configuration item which is conditional on a tag is
            made so by "tag:<tag>". The NOT operator changes to '!',
            which is a bit more intuitive too. Dhcp-host directives
            can set more than one tag now. The old '#' NOT,
            "net:" prefix and no-prefixes are still honoured, so
            no existing config file needs to be changed, but
            the documentation and new-style config files should be
            much less confusing.

            Added --tag-if to allow boolean operations on tags.
            This allows complicated logic to be clearer and more
            general. A great suggestion from Richard Voigt.

            Add broadcast/unicast information to DHCP logging.

            Allow --dhcp-broadcast to be unconditional.

            Fixed incorrect behaviour with NOT <tag> conditionals in
            dhcp-options. Thanks to Max Turkewitz for assistance
            finding this.

            If we send vendor-class encapsulated options based on the
            vendor-class supplied by the client, and no explicit
            vendor-class option is given, echo back the vendor-class
            from the client.

            Fix bug which stopped dnsmasq from matching both a
            circuitid and a remoteid. Thanks to Ignacio Bravo for
            finding this.

            Add --dhcp-proxy, which makes it possible to configure
            dnsmasq to use a DHCP relay agent as a full proxy, with
            all DHCP messages passing through the proxy. This is
            useful if the relay adds extra information to the packets
            it forwards, but cannot be configured with the RFC 5107
            server-override option.

            Added interface:<iface name> part to dhcp-range. The
            semantics of this are very odd at first sight, but it
            allows a single line  of the form
                dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
            to be added to dnsmasq configuration which then supplies
            DHCP and DNS services to that interface, without affecting
            what services are supplied to other interfaces and
            irrespective of the existance or lack of
                interface=<interface>
            lines elsewhere in the dnsmasq configuration. The idea is
            that such a line can be added automatically by libvirt
            or equivalent systems, without disturbing any manual
            configuration.

            Similarly to the above, allow --enable-tftp=<interface>

            Allow a TFTP root to be set separately for requests via
            different interfaces, --tftp-root=<path>,<interface>


            Correctly handle and log clashes between CNAMES and
            DNS names being given to DHCP leases. This fixes a bug
            which caused nonsense IP addresses to be logged. Thanks to
            Sergei Zhirikov for finding and analysing the problem.

            Tweak flush_log so as to avoid leaving the log
            file in non-blocking mode. O_NONBLOCK is a property of the
            file, not the process/descriptor.

            Fix contrib/Solaris10/create_package
            (/usr/man -> /usr/share/man) Thanks to Vita Batrla.

            Fix a problem where, if a client got a lease, then went
            to another subnet and got another lease, then moved back,
            it couldn't resume the old lease, but would instead get
            a new address. Thanks to Leonardo Rodrigues for spotting
            this and testing the fix.

            Fix weird bug which sometimes omitted certain characters
            from the start of quoted strings in dhcp-options. Thanks
            to Dayton Turner for spotting the problem.

            Add facility to redirect some domains to the standard
            upstream servers: this allows something like
            --server=/google.com/1.2.3.4 --server=/www.google.com/#
            which will send queries for *.google.com to 1.2.3.4,
            except *www.google.com which will be forwarded as usual.
            Thanks to AJ Weber for prompting this addition.

            Improve the hash-algorithm used to generate IP addresses
            from MAC addresses during initial DHCP address
            allocation. This improves performance when large numbers
            of hosts with similar MAC addresses all try and get an IP
            address at the same time. Thanks to Paul Smith for his
            work on this.

            Tweak DHCP code so that --bridge-interface can be used to
            select which IP alias of an interface should be used for
            DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
            then adding  --bridge-interface=eth0:dhcp,eth0 will use
            the address of eth0:dhcp to determine the correct subnet
            for DHCP address allocation. Thanks to Pawel Golaszewski
            for prompting this and Eric Cooper for further testing.

            Add --dhcp-generate-names. Suggestion by Ferenc Wagner.

            Tweak DNS server selection algorithm when there is more
            than one server available for a domain, eg.
            --server=/mydomain/1.1.1.1
            --server=/mydomain/2.2.2.2
            Thanks to Alberto Cuesta-Canada for spotting a weakness
            here.

            Add --max-ttl. Thanks to Fredrik Ringertz for the patch.

            Allow --log-facility=- to force all logging to
            stderr. Suggestion from Clemens Fischer.

            Fix regression which caused configuration like
            --address=/.domain.com/1.2.3.4 to be rejected. The dot to 		
            the left of the domain has been implied and not required for
            a long time, but it should be accepted for backward
            compatibility. Thanks to Andrew Burcin for spotting this.

            Add --rebind-domain-ok and --rebind-localhost-ok.
            Suggestion from Clemens Fischer.

            Log replies to queries of type TXT, when --log-queries
            is set.

            Fix compiler warnings when compiled with -DNO_DHCP. Thanks
            to Shantanu Gadgil for the patch.

            Updated French translation. Thanks to Gildas Le Nadan.

            Updated Polish translation. Thanks to Jan Psota.

            Updated German translation. Thanks to Matthias Andree.

            Added contrib/static-arp, thanks to Darren Hoo.

            Fix corruption of the domain when a name from /etc/hosts
            overrides one supplied by a DHCP client. Thanks to Fedor
            Kozhevnikov for spotting the problem.

            Updated Spanish translation. Thanks to Chris Chatham.
