RHEL 5.2 beta has been released. Red Hat engineers backport many of the new features from later kernels to the Red Hat Enterprise Linux 5 kernel, such as support for new hardware and virtualization enhancements. This provides Red Hat Enterprise Linux subscribers with important new capabilities while maintaining stable application interfaces — so that applications continue to run after new updates are installed. And, of course, itâ€™s always worth repeating that updates, which are released about twice a year, are included with every Red Hat Enterprise Linux subscription.
This will give our you a chance to see what your systems will be running later this year. You can grab beta version from RHN.
