version 2.75
            Fix reversion on 2.74 which caused 100% CPU use when a 
	    dhcp-script is configured. Thanks to Adrian Davey for
	    reporting the bug and testing the fix.

	
version 2.74
            Fix reversion in 2.73 where --conf-file would attempt to
	    read the default file, rather than no file.

	    Fix inotify code to handle dangling symlinks better and
	    not SEGV in some circumstances.

	    DNSSEC fix. In the case of a signed CNAME generated by a
	    wildcard which pointed to an unsigned domain, the wrong
            status would be logged, and some necessary checks omitted.
	

version 2.73
            Fix crash at startup when an empty suffix is supplied to
	    --conf-dir, also trivial memory leak. Thanks to 
	    Tomas Hozza for spotting this.

	    Remove floor of 4096 on advertised EDNS0 packet size when 
	    DNSSEC in use, the original rationale for this has long gone.
	    Thanks to Anders Kaseorg for spotting this.

	    Use inotify for checking on updates to /etc/resolv.conf and
	    friends under Linux. This fixes race conditions when the files are 
	    updated rapidly and saves CPU by noy polling. To build
	    a binary that runs on old Linux kernels without inotify,
	    use make COPTS=-DNO_INOTIFY

	    Fix breakage of --domain=<domain>,<subnet>,local - only reverse
	    queries were intercepted. THis appears to have been broken 
	    since 2.69. Thanks to Josh Stone for finding the bug.

	    Eliminate IPv6 privacy addresses and deprecated addresses from
	    the answers given by --interface-name. Note that reverse queries
	    (ie looking for names, given addresses) are not affected. 
	    Thanks to Michael Gorbach for the suggestion.

	    Fix crash in DNSSEC code with long RRs. Thanks to Marco Davids
	    for the bug report.
	    
	    Add --ignore-address option. Ignore replies to A-record 
	    queries which include the specified address. No error is
	    generated, dnsmasq simply continues to listen for another 
	    reply. This is useful to defeat blocking strategies which
	    rely on quickly supplying a forged answer to a DNS 
	    request for certain domains, before the correct answer can
            arrive. Thanks to Glen Huang for the patch.
	
	    Revisit the part of DNSSEC validation which determines if an 
	    unsigned answer is legit, or is in some part of the DNS 
	    tree which should be signed. Dnsmasq now works from the 
	    DNS root downward looking for the limit of signed 
	    delegations, rather than working bottom up. This is 
	    both more correct, and less likely to trip over broken 
	    nameservers in the unsigned parts of the DNS tree 
	    which don't respond well to DNSSEC queries.

	    Add --log-queries=extra option, which makes logs easier
	    to search automatically.

	    Add --min-cache-ttl option. I've resisted this for a long 
	    time, on the grounds that disbelieving TTLs is never a 
	    good idea, but I've been persuaded that there are 
	    sometimes reasons to do it. (Step forward, GFW).
	    To avoid misuse, there's a hard limit on the TTL 
	    floor of one hour. Thansk to RinSatsuki for the patch.

	    Cope with multiple interfaces with the same link-local 
	    address. (IPv6 addresses are scoped, so this is allowed.)
	    Thanks to Cory Benfield for help with this.

	    Add --dhcp-hostsdir. This allows addition of new host
	    configurations to a running dnsmasq instance much more 
	    cheaply than having dnsmasq re-read all its existing
	    configuration each time. 
	
	    Don't reply to DHCPv6 SOLICIT messages if we're not 
	    configured to do stateful DHCPv6. Thanks to Win King Wan 
	    for the patch.

	    Fix broken DNSSEC validation of ECDSA signatures.

	    Add --dnssec-timestamp option, which provides an automatic
	    way to detect when the system time becomes valid after 
	    boot on systems without an RTC, whilst allowing DNS 
	    queries before the clock is valid so that NTP can run. 
	    Thanks to Kevin Darbyshire-Bryant for developing this idea.

	    Add --tftp-no-fail option. Thanks to Stefan Tomanek for
	    the patch.

	    Fix crash caused by looking up servers.bind, CHAOS text 
	    record, when more than about five --servers= lines are 
	    in the dnsmasq config. This causes memory corruption 
	    which causes a crash later. Thanks to Matt Coddington for 
	    sterling work chasing this down.

	    Fix crash on receipt of certain malformed DNS requests.
	    Thanks to Nick Sampanis for spotting the problem.
	    Note that this is could allow the dnsmasq process's
	    memory to be read by an attacker under certain
	    circumstances, so it has a CVE, CVE-2015-3294 

            Fix crash in authoritative DNS code, if a .arpa zone 
	    is declared as authoritative, and then a PTR query which
	    is not to be treated as authoritative arrived. Normally, 
	    directly declaring .arpa zone as authoritative is not 
	    done, so this crash wouldn't be seen. Instead the 
	    relevant .arpa zone should be specified as a subnet
	    in the auth-zone declaration. Thanks to Johnny S. Lee
	    for the bugreport and initial patch.

	    Fix authoritative DNS code to correctly reply to NS 
	    and SOA queries for .arpa zones for which we are 
	    declared authoritative by means of a subnet in auth-zone.
	    Previously we provided correct answers to PTR queries
	    in such zones (including NS and SOA) but not direct
	    NS and SOA queries. Thanks to Johnny S. Lee for 
 	    pointing out the problem.

	    Fix logging of DHCPREPLY which should be suppressed 
	    by quiet-dhcp6. Thanks to J. Pablo Abonia for 
	    spotting the problem.

	    Try and handle net connections with broken fragmentation 
	    that lose large UDP packets. If a server times out, 
            reduce the maximum UDP packet size field in the EDNS0
	    header to 1280 bytes. If it then answers, make that
	    change permanent.

	    Check IPv4-mapped IPv6 addresses when --stop-rebind
	    is active. Thanks to Jordan Milne for spotting this.

	    Allow DHCPv4 options T1 and T2 to be set using --dhcp-option.
	    Thanks to Kevin Benton for patches and work on this.

            Fix code for DHCPCONFIRM DHCPv6 messages to confirm addresses
	    in the correct subnet, even of not in dynamic address 
	    allocation range. Thanks to Steve Hirsch for spotting
	    the problem.

	    Add AddDhcpLease and DeleteDhcpLease DBus methods. Thanks
	    to Nicolas Cavallari for the patch.

	    Allow configuration of router advertisements without the 
	    "on-link" bit set. Thanks to Neil Jerram for the patch.

	    Extend --bridge-interface to DHCPv6 and router 
	    advertisements. Thanks to Neil Jerram for the patch.
	
	
version 2.72
            Add ra-advrouter mode, for RFC-3775 mobile IPv6 support.

	    Add support for "ipsets" in *BSD, using pf. Thanks to 
	    Sven Falempim for the patch.

	    Fix race condition which could lock up dnsmasq when an 
	    interface goes down and up rapidly. Thanks to Conrad 
	    Kostecki for helping to chase this down.

	    Add DBus methods SetFilterWin2KOption and SetBogusPrivOption
	    Thanks to the Smoothwall project for the patch.

	    Fix failure to build against Nettle-3.0. Thanks to Steven 
	    Barth for spotting this and finding the fix. 
	    
	    When assigning existing DHCP leases to intefaces by comparing 
	    networks, handle the case that two or more interfaces have the
	    same network part, but different prefix lengths (favour the
	    longer prefix length.) Thanks to Lung-Pin Chang for the 
	    patch.
	    
	    Add a mode which detects and removes DNS forwarding loops, ie 
	    a query sent to an upstream server returns as a new query to 
	    dnsmasq, and would therefore be forwarded again, resulting in 
	    a query which loops many times before being dropped. Upstream
	    servers which loop back are disabled and this event is logged.
	    Thanks to Smoothwall for their sponsorship of this feature.

	    Extend --conf-dir to allow filtering of files. So
	    --conf-dir=/etc/dnsmasq.d,\*.conf
	    will load all the files in /etc/dnsmasq.d which end in .conf
 
            Fix bug when resulted in NXDOMAIN answers instead of NODATA in
            some circumstances.

	    Fix bug which caused dnsmasq to become unresponsive if it 
	    failed to send packets due to a network interface disappearing.
	    Thanks to Niels Peen for spotting this.
	    	    
            Fix problem with --local-service option on big-endian platforms
	    Thanks to Richard Genoud for the patch.

	
version 2.71
            Subtle change to error handling to help DNSSEC validation 
	    when servers fail to provide NODATA answers for 
	    non-existent DS records.

	    Tweak code which removes DNSSEC records from answers when
	    not required. Fixes broken answers when additional section
	    has real records in it. Thanks to Marco Davids for the bug 
	    report.

	    Fix DNSSEC validation of ANY queries. Thanks to Marco Davids
	    for spotting that too.

	    Fix total DNS failure and 100% CPU use if cachesize set to zero,
	    regression introduced in 2.69. Thanks to James Hunt and
	    the Ubuntu crowd for assistance in fixing this.


version 2.70
            Fix crash, introduced in 2.69, on TCP request when dnsmasq
	    compiled with DNSSEC support, but running without DNSSEC
	    enabled. Thanks to Manish Sing for spotting that one.

	    Fix regression which broke ipset functionality. Thanks to 
	    Wang Jian for the bug report.


version 2.69
	    Implement dynamic interface discovery on *BSD. This allows
	    the contructor: syntax to be used in dhcp-range for DHCPv6
	    on the BSD platform. Thanks to Matthias Andree for
	    valuable research on how to implement this.

	    Fix infinite loop associated with some --bogus-nxdomain
	    configs. Thanks fogobogo for the bug report.

	    Fix missing RA RDNS option with configuration like
	    --dhcp-option=option6:23,[::] Thanks to Tsachi Kimeldorfer
	    for spotting the problem.

	    Add [fd00::] and [fe80::] as special addresses in DHCPv6
	    options, analogous to [::]. [fd00::] is replaced with the
	    actual ULA of the interface on the machine running
	    dnsmasq, [fe80::] with the link-local address. 
	    Thanks to Tsachi Kimeldorfer for championing this.

	    DNSSEC validation and caching. Dnsmasq needs to be
	    compiled with this enabled, with 
	    
	    make dnsmasq COPTS=-DHAVE_DNSSEC
	    
	    this add dependencies on the nettle crypto library and the 
	    gmp maths library. It's possible to have these linked
	    statically with
	    
	    make dnsmasq COPTS='-DHAVE_DNSSEC -DHAVE_DNSSEC_STATIC'
	    
	    which bloats the dnsmasq binary, but saves the size of 
	    the shared libraries which are much bigger.

	    To enable, DNSSEC, you will need a set of
	    trust-anchors. Now that the TLDs are signed, this can be
	    the keys for the root zone, and for convenience they are
	    included in trust-anchors.conf in the dnsmasq
	    distribution. You should of course check that these are
	    legitimate and up-to-date. So, adding
	    
	    conf-file=/path/to/trust-anchors.conf
	    dnssec

	    to your config is all thats needed to get things
	    working. The upstream nameservers have to be DNSSEC-capable
	    too, of course. Many ISP nameservers aren't, but the
	    Google public nameservers (8.8.8.8 and 8.8.4.4) are.
	    When DNSSEC is configured, dnsmasq validates any queries 
	    for domains which are signed. Query results which are 
	    bogus are replaced with SERVFAIL replies, and results 
	    which are correctly signed have the AD bit set. In 
	    addition, and just as importantly, dnsmasq supplies 
	    correct DNSSEC information to clients which are doing 
	    their own validation, and caches DNSKEY, DS and RRSIG
	    records, which significantly improve the performance of 
	    downstream validators. Setting --log-queries will show 
	    DNSSEC in action.

	    If a domain is returned from an upstream nameserver without 
	    DNSSEC signature, dnsmasq by default trusts this. This 
	    means that for unsigned zone (still the majority) there 
	    is effectively no cost for having DNSSEC enabled. Of course
	    this allows an attacker to replace a signed record with a 
	    false unsigned record. This is addressed by the 
	    --dnssec-check-unsigned flag, which instructs dnsmasq
	    to prove that an unsigned record is legitimate, by finding  
	    a secure proof that the zone containing the record is not
	    signed. Doing this has costs (typically one or two extra
	    upstream queries). It also has a nasty failure mode if
	    dnsmasq's upstream nameservers are not DNSSEC capable. 
	    Without --dnssec-check-unsigned using such an upstream
	    server will simply result in not queries being validated; 
	    with --dnssec-check-unsigned enabled and a 
	    DNSSEC-ignorant upstream server, _all_ queries will fail.

	    Note that DNSSEC requires that the local time is valid and 
	    accurate, if not then DNSSEC validation will fail. NTP 
	    should be running. This presents a problem for routers
	    without a battery-backed clock. To set the time needs NTP 
	    to do DNS lookups, but lookups will fail until NTP has run.
	    To address this, there's a flag, --dnssec-no-timecheck 
	    which disables the time checks (only) in DNSSEC. When dnsmasq
	    is started and the clock is not synced, this flag should
	    be used. As soon as the clock is synced, SIGHUP dnsmasq. 
	    The SIGHUP clears the cache of partially-validated data and
	    resets the no-timecheck flag, so that all DNSSEC checks 
	    henceforward will be complete.
	    
	    The development of DNSSEC in dnsmasq was started by 
	    Giovanni Bajo, to whom huge thanks are owed. It has been
	    supported by Comcast, whose techfund grant has allowed for 
	    an invaluable period of full-time work to get it to 
	    a workable state.
 
	    Add --rev-server. Thanks to Dave Taht for suggesting this.
	    
	    Add --servers-file. Allows dynamic update of upstream servers 
	    full access to configuration. 

	    Add --local-service. Accept DNS queries only from hosts 
            whose address is on a local subnet, ie a subnet for which 
            an interface exists on the server. This option
            only has effect if there are no --interface --except-interface,
            --listen-address or --auth-server options. It is intended 
            to be set as a default on installation, to allow
            unconfigured installations to be useful but also safe from 
	    being used for DNS amplification attacks.

	    Fix crashes in cache_get_cname_target() when dangling CNAMEs
	    encountered. Thanks to Andy and the rt-n56u project for
	    find this and helping to chase it down.

	    Fix wrong RCODE in authoritative DNS replies to PTR queries. The
	    correct answer was included, but the RCODE was set to NXDOMAIN.
	    Thanks to Craig McQueen for spotting this.

	    Make statistics available as DNS queries in the .bind TLD as 
	    well as logging them.


version 2.68
            Use random addresses for DHCPv6 temporary address
            allocations, instead of algorithmically determined stable
            addresses.

	    Fix bug which meant that the DHCPv6 DUID was not available
	    in DHCP script runs during the lifetime of the dnsmasq
	    process which created the DUID de-novo. Once the DUID was
	    created and stored in the lease file and dnsmasq
	    restarted, this bug disappeared.

	    Fix bug introduced in 2.67 which could result in erroneous
	    NXDOMAIN returns to CNAME queries.

	    Fix build failures on MacOS X and openBSD.

	    Allow subnet specifications in --auth-zone to be interface 
	    names as well as address literals. This makes it possible
	    to configure authoritative DNS when local address ranges
	    are dynamic and works much better than the previous
	    work-around which exempted contructed DHCP ranges from the
	    IP address filtering. As a consequence, that work-around
	    is removed. Under certain circumstances, this change wil
	    break existing configuration: if you're relying on the
	    contructed-range exception, you need to change --auth-zone
	    to specify the same interface as is used to construct your
	    DHCP ranges, probably with a trailing "/6" like this: 
	    --auth-zone=example.com,eth0/6 to limit the addresses to
	    IPv6 addresses of eth0.

	    Fix problems when advertising deleted IPv6 prefixes. If
	    the prefix is deleted (rather than replaced), it doesn't
	    get advertised with zero preferred time. Thanks to Tsachi
	    for the bug report. 

	    Fix segfault with some locally configured CNAMEs. Thanks
	    to Andrew Childs for spotting the problem.

	    Fix memory leak on re-reading /etc/hosts and friends,
	    introduced in 2.67.

	    Check the arrival interface of incoming DNS and TFTP
	    requests via IPv6, even in --bind-interfaces mode. This
	    isn't possible for IPv4 and can generate scary warnings,
	    but as it's always possible for IPv6 (the API always
	    exists) then we should do it always. 
	    
	    Tweak the rules on prefix-lengths in --dhcp-range for
	    IPv6. The new rule is that the specified prefix length
	    must be larger than or equal to the prefix length of the
	    corresponding address on the local interface. 


version 2.67
	    Fix crash if upstream server returns SERVFAIL when
	    --conntrack in use. Thanks to Giacomo Tazzari for finding
	    this and supplying the patch. 

	    Repair regression in 2.64. That release stopped sending
	    lease-time information in the reply to DHCPINFORM
	    requests, on the correct grounds that it was a standards
	    violation. However, this broke the dnsmasq-specific
	    dhcp_lease_time utility. Now, DHCPINFORM returns
	    lease-time only if it's specifically requested
	    (maintaining standards) and the dhcp_lease_time utility
	    has been taught to ask for it (restoring functionality). 

	    Fix --dhcp-match, --dhcp-vendorclass and --dhcp-userclass
	    to work with BOOTP and well as DHCP. Thanks to Peter
	    Korsgaard for spotting the problem. 

	    Add --synth-domain. Thanks to Vishvananda Ishaya for
	    suggesting this.

	    Fix failure to compile ipset.c if old kernel headers are
	    in use. Thanks to Eugene Rudoy for pointing this out.

	    Handle IPv4 interface-address labels in Linux. These are
	    often used to emulate the old IP-alias addresses. Before,
	    using --interface=eth0 would service all the addresses of
	    eth0, including ones configured as aliases, which appear
	    in ifconfig as eth0:0. Now, only addresses with the label
	    eth0 are active. This is not backwards compatible: if you
	    want to continue to bind the aliases too, you need to add
	    eg. --interface=eth0:0 to the config. 
	
	    Fix "failed to set SO_BINDTODEVICE on DHCP socket: Socket 
	    operation on non-socket" error on startup with
	    configurations which have exactly one --interface option
	    and do RA but _not_ DHCPv6. Thanks to Trever Adams for the
	    bug report.

	    Generalise --interface-name to cope with IPv6 addresses
	    and multiple addresses per interface per address family.

	    Fix option parsing for --dhcp-host, which was generating a
	    spurious error when all seven possible items were
	    included. Thanks to Zhiqiang Wang for the bug report.

	    Remove restriction on prefix-length in --auth-zone. Thanks
	    to Toke Hoiland-Jorgensen for suggesting this.

	    Log when the maximum number of concurrent DNS queries is
	    reached. Thanks to Marcelo Salhab Brogliato for the patch.

	    If wildcards are used in --interface, don't assume that 
	    there will only ever be one available interface for DHCP
	    just because there is one at start-up. More may appear, so
	    we can't use SO_BINDTODEVICE. Thanks to Natrio for the bug
	    report. 

	    Increase timeout/number of retries in TFTP to accomodate
	    AudioCodes Voice Gateways doing streaming writes to flash.
	    Thanks to Damian Kaczkowski for spotting the problem.

	    Fix crash with empty DHCP string options when adding zero
	    terminator. Thanks to Patrick McLean for the bug report.

	    Allow hostnames to start with a number, as allowed in
	    RFC-1123. Thanks to Kyle Mestery for the patch. 

	    Fixes to DHCP FQDN option handling: don't terminate FQDN
	    if domain not known and allow a FQDN option with blank
	    name to request that a FQDN option is returned in the
	    reply. Thanks to Roy Marples for the patch.

	    Make --clear-on-reload apply to setting upstream servers
	    via DBus too.

	    When the address which triggered the construction of an
	    advertised IPv6 prefix disappears, continue to advertise 
	    the prefix for up to 2 hours, with the preferred lifetime
	    set to zero. This satisfies RFC 6204 4.3 L-13 and makes
	    things work better if a prefix disappears without being
	    deprecated first. Thanks to Uwe Schindler for persuasively
	    arguing for this.

	    Fix MAC address enumeration on *BSD. Thanks to Brad Smith
	    for the bug report.

	    Support RFC-4242 information-refresh-time options in the 
	    reply to DHCPv6 information-request. The lease time of the
            smallest valid dhcp-range is sent. Thanks to Uwe Schindler 
	    for suggesting this.

	    Make --listen-address higher priority than --except-interface
	    in all circumstances. Thanks to Thomas Hood for the bugreport.

	    Provide independent control over which interfaces get TFTP 
	    service. If enable-tftp is given a list of interfaces, then TFTP 
	    is provided on those. Without the list, the previous behaviour
	    (provide TFTP to the same interfaces we provide DHCP to) 
	    is retained. Thanks to Lonnie Abelbeck for the suggestion.

	    Add --dhcp-relay config option. Many thanks to vtsl.net
	    for sponsoring this development.

	    Fix crash with empty tag: in --dhcp-range. Thanks to
	    Kaspar Schleiser for the bug report.

	    Add "baseline" and "bloatcheck" makefile targets, for 
	    revealing size changes during development. Thanks to
	    Vladislav Grishenko for the patch. 

	    Cope with DHCPv6 clients which send REQUESTs without
	    address options - treat them as SOLICIT with rapid commit.

	    Support identification of clients by MAC address in
	    DHCPv6. When using a relay, the relay must support RFC
	    6939 for this to work. It always works for directly
	    connected clients. Thanks to Vladislav Grishenko
	    for prompting this feature.
	    
	    Remove the rule for constructed DHCP ranges that the local
	    address must be either the first or last address in the
	    range. This was originally to avoid SLAAC addresses, but
	    we now explicitly autoconfig and privacy addresses instead.  

	    Update Polish translation. Thanks to Jan Psota.

	    Fix problem in DHCPv6 vendorclass/userclass matching
	    code. Thanks to Tanguy Bouzeloc for the patch.

 	    Update Spanish transalation. Thanks to Vicente Soriano.

	    Add --ra-param option. Thanks to Vladislav Grishenko for
	    inspiration on this.

	    Add --add-subnet configuration, to tell upstream DNS
	    servers where the original client is. Thanks to DNSthingy
	    for sponsoring this feature.

	    Add --quiet-dhcp, --quiet-dhcp6 and --quiet-ra. Thanks to
	    Kevin Darbyshire-Bryant for the initial patch.

	    Allow A/AAAA records created by --interface-name to be the
	    target of --cname. Thanks to Hadmut Danisch for the
	    suggestion. 

	    Avoid treating a --dhcp-host which has an IPv6 address
	    as eligable for use with DHCPv4 on the grounds that it has
	    no address, and vice-versa. Thanks to Yury Konovalov for
	    spotting the problem.

	    Do a better job caching dangling CNAMEs. Thanks to Yves
	    Dorfsman for spotting the problem.

 
version 2.66
            Add the ability to act as an authoritative DNS
            server. Dnsmasq can now answer queries from the wider 'net
            with local data, as long as the correct NS records are set
            up. Only local data is provided, to avoid creating an open
            DNS relay. Zone transfer is supported, to allow secondary
            servers to be configured.

	    Add "constructed DHCP ranges" for DHCPv6. This is intended
	    for IPv6 routers which get prefixes dynamically via prefix
	    delegation. With suitable configuration, stateful DHCPv6
	    and RA can happen automatically as prefixes are delegated
	    and then deprecated, without having  to re-write the
	    dnsmasq configuration file or restart the daemon. Thanks to
	    Steven Barth for extensive testing and development work on
	    this idea.

	    Fix crash on startup on Solaris 11. Regression probably
	    introduced in 2.61.  Thanks to Geoff Johnstone for the
	    patch.

	    Add code to make behaviour for TCP DNS requests that same
	    as for UDP requests, when a request arrives for an allowed 
	    address, but via a banned interface. This change is only
	    active on Linux, since the relevant API is missing (AFAIK)
	    on other platforms. Many thanks to Tomas Hozza for
	    spotting the problem, and doing invaluable discovery of
	    the obscure and undocumented API required for the solution.

	    Don't send the default DHCP option advertising dnsmasq as
	    the local DNS server if dnsmasq is configured to not act
	    as DNS server, or it's configured to a non-standard port.
 
            Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
            DNSMASQ_REMOTE_ID variables to the environment of the
            lease-change script (and the corresponding Lua). These hold
            information inserted into the DHCP request by a DHCP relay
            agent. Thanks to Lakefield Communications for providing a
            bounty for this addition.
 
	    Fixed crash, introduced in 2.64, whilst handling DHCPv6
	    information-requests with some common configurations.
	    Thanks to Robert M. Albrecht for the bug report and 
	    chasing the problem.

	    Add --ipset option. Thanks to Jason A. Donenfeld for the 
	    patch.

	    Don't erroneously reject some option names in --dhcp-match
	    options. Thanks to Benedikt Hochstrasser for the bug report.
	    
	    Allow a trailing '*' wildcard in all interface-name
	    configurations. Thanks to Christian Parpart for the patch.

	    Handle the situation where libc headers define
	    SO_REUSEPORT, but the kernel in use doesn't, to cope with
	    the introduction of this option to Linux. Thanks to Rich
	    Felker for the bug report.

	    Update Polish translation. Thanks to Jan Psota.

	    Fix crash if the configured DHCP lease limit is
	    reached. Regression occurred in 2.61. Thanks to Tsachi for
	    the bug report. 
	    
	    Update the French translation. Thanks to Gildas le Nadan.

  
version 2.65
	    Fix regression which broke forwarding of queries sent via
	    TCP which are not for A and AAAA and which were directed to
	    non-default servers. Thanks to Niax for the bug report.

	    Fix failure to build with DHCP support excluded. Thanks to 
	    Gustavo Zacarias for the patch.
	    
	    Fix nasty regression in 2.64 which completely broke cacheing.


version 2.64
            Handle DHCP FQDN options with all flag bits zero and
            --dhcp-client-update set. Thanks to Bernd Krumbroeck for
            spotting the problem.

	    Finesse the check for /etc/hosts names which conflict with
	    DHCP names. Previously a name/address pair in /etc/hosts
	    which didn't match the name/address of a DHCP lease would
	    generate a warning. Now that only happesn if there is not
	    also a match. This allows multiple addresses for a name in 
	    /etc/hosts with one of them assigned via DHCP.

	    Fix broken vendor-option processing for BOOTP. Thanks to
	    Hans-Joachim Baader for the bug report.

	    Don't report spurious netlink errors, regression in
	    2.63. Thanks to Vladislav Grishenko for the patch.

	    Flag DHCP or DHCPv6 in starup logging. Thanks to 
	    Vladislav Grishenko for the patch.

	    Add SetServersEx method in DBus interface. Thanks to Dan
	    Williams for the patch.

	    Add SetDomainServers method in DBus interface. Thanks to
	    Roy Marples for the patch.

	    Fix build with later Lua libraries. Thansk to Cristian
	    Rodriguez for the patch.

	    Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
	    for the patch.

	    Fix breakage of --host-record parsing, resulting in
	    infinte loop at startup. Regression in 2.63. Thanks to
	    Haim Gelfenbeyn for spotting this.

	    Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
	    socket, this allows multiple instances of dnsmasq on a
	    single machine, in the same way as for DHCPv4. Thanks to
	    Gene Czarcinski and Vladislav Grishenko for work on this.

	    Fix DHCPv6 to do access control correctly when it's 
	    configured with --listen-address. Thanks to
	    Gene Czarcinski for sorting this out. 

	    Add a "wildcard" dhcp-range which works for any IPv6
	    subnet, --dhcp-range=::,static Useful for Stateless 
	    DHCPv6. Thanks to Vladislav Grishenko for the patch.

	    Don't include lease-time in DHCPACK replies to DHCPINFORM
	    queries, since RFC-2131 says we shouldn't. Thanks to
	    Wouter Ibens for pointing this out.  

	    Makefile tweak to do dependency checking on header files.
	    Thanks to Johan Peeters for the patch.

	    Check interface for outgoing unsolicited router 
	    advertisements, rather than relying on interface address 
	    configuration. Thanks to Gene Czarinski for the patch.

	    Handle better attempts to transmit on interfaces which are
	    still doing DAD, and specifically do not just transmit
	    without setting source address and interface, since this
	    can cause very puzzling effects when a router
	    advertisement goes astray. Thanks again to Gene Czarinski.

	    Get RA timers right when there is more than one
	    dhcp-range on a subnet.
	    

version 2.63
            Do duplicate dhcp-host address check in --test mode.

	    Check that tftp-root directories are accessible before
	    start-up. Thanks to Daniel Veillard for the initial patch.

	    Allow more than one --tfp-root flag. The per-interface
	    stuff is pointless without that.

	    Add --bind-dynamic. A hybrid mode between the default and
	    --bind-interfaces which copes with dynamically created
	    interfaces. 
	    
	    A couple of fixes to the build system for Android. Thanks
	    to Metin Kaya for the patches.

	    Remove the interface:<interface> argument in --dhcp-range, and
	    the interface argument to --enable-tftp. These were a
	    still-born attempt to allow automatic isolated
	    configuration by libvirt, but have never (to my knowledge)
	    been used, had very strange semantics, and have been
	    superceded by other mechanisms. 

	    Fixed bug logging filenames when duplicate dhcp-host
	    addresses are found. Thanks to John Hanks for the patch.

	    Fix regression in 2.61 which broke caching of CNAME
	    chains. Thanks to Atul Gupta for the bug report.

	    Allow the target of a --cname flag to be another --cname.

            Teach DHCPv6 about the RFC 4242 information-refresh-time
	    option, and add parsing if the minutes, hours and days
	    format for options. Thanks to Francois-Xavier Le Bail for
	    the suggestion.

	    Allow "w" (for week) as multiplier in lease times, as well
	    as seconds, minutes, hours and days.  Álvaro Gámez Machado 
	    spotted the ommission.
 
	    Update French translation. Thanks to Gildas Le Nadan.

	    Allow a DBus service name to be given with --enable-dbus
	    which overrides the default,
	    uk.org.thekelleys.dnsmasq. Thanks to Mathieu
	    Trudel-Lapierre for the patch. 

	    Set the "prefix on-link" bit in Router
	    Advertisements. Thanks to Gui Iribarren for the patch.


version 2.62
            Update German translation. Thanks to Conrad Kostecki.

	    Cope with router-solict packets wich don't have a valid 
	    source address. Thanks to Vladislav Grishenko for the patch.

	    Fixed bug which caused missing periodic router
	    advertisements with some configurations. Thanks to
	    Vladislav Grishenko for the patch.

	    Fixed bug which broke DHCPv6/RA with prefix lengths 
	    which are not divisible by 8. Thanks to Andre Coetzee 
	    for spotting this.

	    Fix non-response to router-solicitations when
	    router-advertisement configured, but DHCPv6 not
	    configured. Thanks to Marien Zwart for the patch.

	    Add --dns-rr, to allow arbitrary DNS resource records.

	    Fixed bug which broke RA scheduling when an interface had
	    two addresses in the same network. Thanks to Jim Bos for
	    his help nailing this.

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.

	    Explicity 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 Conrad 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
	    aquisition 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.
	    
	    Don't cache data from non-recursive nameservers, since it
	    may erroneously look like a valid CNAME to a non-exitant
	    name. Thanks to Ben Winslow for finding this.

	    Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
	    on exactly one interface and --bind-interfaces is set. This 
	    makes the OpenStack use-case of one dnsmasq per virtual
	    interface work. This is only available on Linux; it's not
	    supported on other platforms. Thanks to Vishvananda Ishaya
	    and the OpenStack team for the suggestion.

	    Updated French translation. Thanks to Gildas Le Nadan.

	    Give correct from-cache answers to explict CNAME queries.
	    Thanks to Rob Zwissler for spotting this.
	    
	    Add --tftp-lowercase option. Thanks to Oliver Rath for the
	    patch. 

	    Ensure that the DBus DhcpLeaseUpdated events are generated
	    when a lease goes through INIT_REBOOT state, even if the
	    dhcp-script is not in use. Thanks to Antoaneta-Ecaterina
	    Ene for the patch.

	    Fix failure of TFTP over IPv4 on OpenBSD platform. Thanks
	    to Brad Smith for spotting this.
	    

version 2.60
            Fix compilation problem in Mac OS X Lion. Thanks to Olaf
            Flebbe for the patch.

	    Fix DHCP when using --listen-address with an IP address
	    which is not the primary address of an interface.

	    Add --dhcp-client-update option.

	    Add Lua integration. Dnsmasq can now execute a DHCP
	    lease-change script written in Lua. This needs to be
	    enabled at compile time by setting HAVE_LUASCRIPT in 
	    src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
	    Thanks to Jan-Piet Mens for the idea and proof-of-concept 
	    implementation.
	    
	    Tidied src/config.h to distinguish between
	    platform-dependent compile-time options which are selected
	    automatically, and builder-selectable compile time
	    options. Document the latter better, and describe how to
	    set them from the make command line.

	    Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
	    confusion. IPPROTO_IP works everywhere now.
	    
	    Set TOS on DHCP sockets, this improves things on busy
	    wireless networks. Thanks to Dave Taht for the patch.

	    Determine VERSION automatically based on git magic:
	    release tags or hash values.

	    Improve start-up speed when reading large hosts files 
	    containing many distinct addresses.

	    Fix problem if dnsmasq is started without the stdin,
	    stdout and stderr file descriptors open. This can manifest
	    itself as 100% CPU use. Thanks to Chris Moore for finding
	    this.

	    Fix shell-scripting bug in bld/pkg-wrapper. Thanks to 
	    Mark Mitchell for the patch.

	    Allow the TFP server or boot server in --pxe-service, to
	    be a domain name instead of an IP address. This allows for
	    round-robin	to multiple servers, in the same way as
	    --dhcp-boot. A good suggestion from Cristiano Cumer.

	    Support BUILDDIR variable in the Makefile. Allows builds 
	    for multiple archs from the same source tree with eg.
	    make BUILDDIR=linux             (relative to dnsmasq tree)
	    make BUILDDIR=/tmp/openbsd      (absolute path)
	    If BUILDDIR is not set, compilation happens in the src
	    directory, as before. Suggestion from Mark Mitchell.

	    Support DHCPv6. Support is there for the sort of things
	    the existing v4 server does, including tags, options, 
	    static addresses and relay support. Missing is prefix 
	    delegation, which is probably not required in the dnsmasq
	    niche, and an easy way to accept prefix delegations from
	    an upstream DHCPv6 server, which is. Future plans include
	    support for DHCPv6 router option and MAC address option
	    (to make selecting clients by MAC address work like IPv4).
	    These will be added as the standards mature.
	    This code has been tested, but this is the first release,
	    so don't bet the farm on it just yet. Many thanks to all 
	    testers who have got it this far.

	    Support IPv6 router advertisements. This is a
	    simple-minded implementation, aimed at providing the
	    vestigial RA needed to go alongside IPv6. Is picks up
	    configuration from the DHCPv6 conf, and should just need
	    enabling with --enable-ra.   

	    Fix long-standing wrinkle with --localise-queries that
	    could result in wrong answers when DNS packets arrive
	    via an interface other than the expected one. Thanks to 
	    Lorenzo Milesi and John Hanks for spotting this one.
 
            Update French translation. Thanks to Gildas Le Nadan.

	    Update Polish translation. Thanks to Jan Psota.


version 2.59
            Fix regression in 2.58 which caused failure to start up
            with some combinations of dnsmasq config and IPv6 kernel
            network config. Thanks to Brielle Bruns for the bug
            report.

            Improve dnsmasq's behaviour when network interfaces are
            still doing duplicate address detection (DAD). Previously,
            dnsmasq would wait up to 20 seconds at start-up for the
            DAD state to terminate. This is broken for bridge
            interfaces on recent Linux kernels, which don't start DAD
            until the bridge comes up, and so can take arbitrary
            time. The new behaviour lets dnsmasq poll for an arbitrary
            time whilst providing service on other interfaces. Thanks
            to Stephen Hemminger for pointing out the problem.


version 2.58
	    Provide a definition of the SA_SIZE macro where it's 
	    missing. Fixes build failure on openBSD.

	    Don't include a zero terminator at the end of messages
	    sent to /dev/log when /dev/log is a datagram socket.
	    Thanks to Didier Rabound for spotting the problem.

	    Add --dhcp-sequential-ip flag, to force allocation of IP
	    addresses in ascending order. Note that the default
	    pseudo-random mode is in general better but some
	    server-deployment applications need this.
