It is deprecated, and does appear to work interchangeably with tag:, in
this context.
 Although I did find it in a 2010 DD-WRT forum post,

Untangle is now based on Debian 6.0 (squeeze) and 2.6.32 kernel

I am using it in Untangle v10.0 as such, in Dnsmasq version 2.55
dnsmasq.conf:
# Interface 2 (eth0) DHCP
dhcp-range=interface:eth0,192.168.113.100,192.168.113.200,86400
dhcp-option=tag:eth0,3,192.168.113.1 # gateway
dhcp-option=tag:eth0,1,255.255.255.0 # netmask
dhcp-option=tag:eth0,6,192.168.113.1 # dns
dhcp-option=tag:eth0,252,"\n" # custom dhcp option

But according to the changelog,
http://www.thekelleys.org.uk/dnsmasq/CHANGELOG

Added interface:<iface name> part to dhcp-range in v2.53
and Remove the interface:<interface> argument in --dhcp-range in v2.63

so, mystery solved, sorry to bother you.

but thanks!
