After less than one month from the first beta, the highly expected XenSource XenEnterprise 3.1, introducing support for Microsoft Windows XP SP2 and 2003 (SP0, SP1 and R2 edition) guest OSes, already reaches release candidate status.
The milestone was indeed expected since XenSource plans to publicly release 3.1 before the end of the year.
No new features has been introduced in this new build. The beta program is still open for enrollment.
