As I wrote in the "sticky" note for this forum
On January 18 2012, ZENworks Patch Management 6.4 reaches end of General Support (see Novell Support | Support Lifecycle )
From that time onwards, the product itself will not be updated, unless a critical security issue is found.
However, patch content (new patches) will continue to be available for customers with a valid subscription, for the remainder of the Extended Support period (which ends January 18 2013).
That day has come - I would encourage everyone to consider moving to ZCM Patch Management ASAP
