Xen Hypervisor 4.4 Released

Xen 4.4 was released on the 10th of March.  Here is a very brief summary of the enhancement achieved in this release.

The ARM port has reached an improved level of stability.  Hypervisor ABI (Application Binary Interface) has been "declared stable" (according to the release notes).  AMD have demonstrated an ARM based Opteron (A1100 Series) recently.  I think this represents the start of a huge potential change to cloud compute engines.  It's early days yet but with this release this future reality moves a lot closer.
