Nagios Problem with secondary_address

I'm running the latest version of Nagios (3.2.3). i discovered that the "secondary_address" object directive is no longer supported. does anyone know what it was replaced with?

i cant find anything on it.

i have a lot ofservers with secondary addresses and they kind of depend on this. how can i go around this?

Thank you.

below is the error message I got:

Error: Invalid host object directive 'secondary_address'.
Error: Could not add object property in file '/prod/nagios/etc/objects/hosts.cfg' on line 718.
   Error processing object config files!
