Red Hat Enterprise Linux 4.9 released
Red Hat has released version 4.9 of its Red Hat Enterprise Linux (RHEL) distribution for corporate customers. The list of new features in the release notes (HTML, PDF ) is rather short, as RHEL 4 is currently in the second phase of the RHEL life cycle, in which the distributor will only make security corrections and other minor changes. Components such as new hardware drivers will only be added if no major effort is required to do so – for instance, in the new RHEL 4 release the distributor updated the micro code that corrects certain flaws in Intel processors. The developers also extended the support of Xeon CPUs in Oprofile, and Firefox was bumped up to the current version 3.6.13.
Now, RHEL 4 will enter the third phase in the life cycle of RHEL distributions, where Red Hat will only fix critical flaws and security holes. Introduced in 2005, the distribution's regular support will end on 29 February 2012; however, customers can purchase Extended Life Cycle Support (ELS), which will provide them with updates for a further three years. Last November, Red Hat introduced RHEL 6, the latest major release of the enterprise distribution. Series 5 arrived at RHEL 5.6 a few weeks ago.
