7.1 security updates ?

Hi, We have one server left running SuSE 7.1, but as far as I can tell we are still getting security updates for this machine. I was expecting the updates to stop when SuSE 8.2 was released, that appears to have been the case in the past. We are working on upgrading this machine, but are experiencing some trouble (hardware related). Is there a date when the security updates for 7.1 will stop ? Thanks -- Daniel Nilsson
