Previous Alpha and Beta Builds

With the availability of the latest pre-release, it is important to note that downloads for prior pre-releases have been removed.


The following pre-release is designed for "clean" installations only. Installing this pre-release as an "upgrade" from prior versions of XenServer is NOT recommended.
