Dnsmasq version 2.46 is now released and available from

The CHANGELOG entry is
version 2.46
Allow --bootp-dynamic to take a netid tag, so that it may
be selectively enabled. Thanks to Olaf Westrik for the
suggestion.
Remove ISC-leasefile reading code. This has been
deprecated for a long time, and last time I removed it, it
ended up going back by request of one user. This time,
it's gone for good; otherwise it would need to be
re-worked to support multiple domains (see below).
Support DHCP clients in multiple DNS domains. This is a
long-standing request. Clients are assigned to a domain
based in their IP address.
Add --dhcp-fqdn flag, which changes behaviour if DNS names
assigned to DHCP clients. When this is set, there must be
a domain associated with each client, and only
fully-qualified domain names are added to the DNS. The
advantage is that the only the FQDN needs to be unique,
so that two or more DHCP clients can share a hostname, as
long as they are in different domains.
Set environment variable DNSMASQ_DOMAIN when invoking
lease-change script. This may be useful information to
have now that it's variable.
Tighten up data-checking code for DNS packet
handling. Thanks to Steve Dodd who found certain illegal
packets which could crash dnsmasq. No memory overwrite was
possible, so this is not a security issue beond the DoS
potential.
Update example config dhcp option 47, the previous
suggestion generated and illegal, zero-length,
option. Thanks to Matthias Andree for finding this.
Rewrite hosts-file reading code to remove the limit of
1024 characters per line. John C Meuser found this.
Create a net-id tag with the name of the interface on
which the DHCP request was received.
Fixed minor memory leak in DBus code, thanks to Jeremy
Laine for the patch.
Emit DBus signals as the DHCP lease database
changes. Thanks to Jeremy Laine for the patch.
Allow for more that one MAC address in a dhcp-host
line. This configuration tells dnsmasq that it's OK to
abandon a DHCP lease of the fixed address to one MAC
address, if another MAC address in the dhcp-host statement
asks for an address. This is useful to give a fixed
address to a host which has two network interfaces
(say, a laptop with wired and wireless interfaces.)
It's very important to ensure that only one interface
at a time is up, since dnsmasq abandons the first lease
and re-uses the address before the leased time has
elapsed. John Gray suggested this.
Tweak the response to a DHCP request packet with a wrong
server-id when --dhcp-authoritative is set; dnsmasq now
returns a DHCPNAK, rather than silently ignoring the
packet. Thanks to Chris Marget for spotting this
improvement.
Add --cname option. This provides a limited alias
function, usable for DHCP names. Thanks to AJ Weber for
suggestions on this.
Updated contrib/webmin with latest version from Neil
Fisher.
Updated Polish translation. Thanks to Jan Psota.
Correct the text names for DHCP options 64 and 65 to be
"nis+-domain" and "nis+-servers".
Updated Spanish translation. Thanks to Chris Chatham.
Force re-reading of /etc/resolv.conf when an "interface
up" event occurs.
Cheers,
Simon.
