Red Hat has released an unashamedly labelled 'minor' release of Red Hat Enterprise Linux.
This 5.9 version features better hardware enablement, security and certification improvements, improved developer tools and refined virtualisation technologies.
The firm positions these so-called minor increments as part of what it calls its "10-year lifecycle" with the platform.
"This release marks the beginning of Production Phase 2 of Red Hat Enterprise Linux 5 and demonstrates the company's continuing effort to promote stability and the preservation of customers' investments in the platform. It maintains Red Hat's commitment to a 10-year lifecycle," said the company, in a press statement.
There is backwards compatibility with both hardware and software platforms across the lifecycle of Red Hat Enterprise Linux 5.
This so-called "hardware enablement" is in fact:
• support for the latest CPU,
• chipsets and,
• device driver enhancements.
On the developer tools front here we see that Red Hat Enterprise Linux 5.9 includes the ability to develop and test with the latest version of open source Java available through OpenJDK 7.
According to Red Hat, the RHEL Enterprise Linux 5.9 enhances the operating system's usability in multi-vendor environments by introducing Microsoft Hyper-V drivers for improved performance.
