Red Hat plans to ship <A HREF="http://news.zdnet.com/2100-3513_22-6146149.html?tag=nl.r23660">the next version of its premium Linux product</A> on February 28, debuting major virtualization technology but missing an earlier deadline by about two months. Red Hat Enterprise Linux 5 had been scheduled to ship by the end of 2006. However, the company began giving itself scheduling wiggle room in September, when Red Hat released the first RHEL 5 beta. A second beta arrived in November.
