“RHEL 5. 9 is the last minor release in Production Phase 1 so, yes, RHEL 5. 9 is the last minor release where we introduce new features for this mission critical product,” Pacheco said.
One of the key areas of improvement with RHEL 5.9 is new hardware enablement such that RHEL will be supported and urn on the latest Intel and AMD chips as well as server vendor systems. Hardware enablement is also a key component for Red Hat active update for the RHEL 6.x platform as well.
