CentOS 6.4 – February 28, 2013.
Microsoft Hyper-V drivers have been added to allow CentOS to be more efficient as a Virtual Machine when installed on Microsoft Hyper-V server.
The samba4 libraries (provided by the samba4-libs package) have been upgraded to the latest upstream version to improve interoperability with Active Directory (AD) domains. If you upgrade from CentOS-6.3 to CentOS-6.4 and you have Samba in use, make sure to uninstall the samba4 package to avoid conflicts during the upgrade. samba4 is still – at least in part – considered a technology preview.
The download is not possible not yet! but it will be soon…
