Netezza: news NPS 7.0 is no longer maintained

From the IBM news letter: 

The last regularly scheduled quarterly Fixpack for NPS v7.0.4 was posted to Fix Central on 2015. While you can still open PMRs for this version and get support, any code changes to address your bug or enhancement will be available only in NPS version 7.1 and later. To obtain the updates, you must upgrade your NPS software to the later release. We strongly recommend that you upgrade NPS to the latest patch level available on NPS v7.2. Contact the customer support team by creating a PMR to upgrade your system. Please note that depending on your current RHEL and firmware levels, the NPS upgrade may require the OS and firmware to be upgraded as well.
