Red Hat has announced the release of Red Hat Enterprise Linux 5 (RHEL5). The Server editions have changed from the AS or ES choices to RHEL or RHEL AP (Advanced Platform). Basic subscriptions for RHEL cost $349 whereas RHEL AP starts at $1499. RHEL now includes virtualization for running up to 4 guest OSes, and RHEL AP can run unlimited guest OSes (well, as much as your hardware can manage).

The Desktop edition Basic Subscription starts at $80, but there are several other Desktop configurations that include Multi-OS virtualization and Workstation ranging up to $339.

The free Red Hat clone CentOS released CentOS 5 Beta earlier this week, and they're expected to post the final version shortly.
