Red Hat Enterprise Linux 6.2 was just released earlier this month, but now that CentOS is used to cranking out the EL6 re-spins, they've managed a nice turn-around time for 6.2. Oracle too has put out their Oracle Linux 6.2 release. Meanwhile, Scientific Linux 6.2 has put out an alpha build but their final 6.2 release isn't quite out yet.
The CentOS 6.2 release announcement for 32-bit and 64-bit Intel/AMD systems is available from this mailing list message. Release notes for version 6.2 are also available.
Oracle Linux 6.2 was released last Thursday and its announcement can be found here.
Upstream Red Hat Enterprise Linux 6.2 offers virtualization optimizations, improved resource management, storage and file-system performance improvements, and much more. Those wanting to read about RHEL 6.2 can do so from this announcement.
