There has been an API change in commit 0bc5ab465849847b0556295d9a2023295c4d169e of 2014-06-27, 10:17:55 UTC in the functions AuthAllow and AuthDeny.

Old:

func AuthAllow(addresses ...string)
func AuthDeny(addresses ...string)

New:

func AuthAllow(domain string, addresses ...string)
func AuthDeny(domain string, addresses ...string)

If domain can be parsed as an IP address, it will be interpreted as such, and it and all remaining addresses are added to all domains.

So this should still work as before:

zmq.AuthAllow("127.0.0.1", "123.123.123.123")

But this won't compile:

a := []string{"127.0.0.1", "123.123.123.123"}
zmq.AuthAllow(a...)

And needs to be rewritten as:

a := []string{"127.0.0.1", "123.123.123.123"}
zmq.AuthAllow("*", a...)

Furthermore, an address can now be a single IP address, as well as an IP address and mask in CIDR notation, e.g. "123.123.123.0/24".
