I have defined Triggers for service state:
Service "ESET HTTP Server" {$SERVICE_STATUS{ITEM.VALUE}} on {HOSTNAME}
and defined global macro:
{$SERVICE_STATUS6} = STOPPED

On Zabbix 1.8 this trigger resolves to
Service "ESET HTTP Server" STOPPED on XXX
but on 2.4.1 i got:
Service "ESET HTTP Server" {$SERVICE_STATUS6} on XXX
