[Dnsmasq-discuss] config error after 2.56 upgrade

[Ben]

So after upgrading from 2.55 to 2.56 I am getting the following error at 
startup:

    dnsmasq: error at line 3 of /etc/dnsmasq.d/options.conf
Line 3 in that file is:

    dhcp-mac=set:special,00:e0:91:*:*:*

So, this has worked happily for a while, but certainly w/ 2.55.  Has 
there been a change in that command or is this a bug in 2.56?

Thanks,

Ben
