First of all there is the news that Anthony Liguori has included kvm support in the main Qemu development tree. In his blogpost Avi Kivity explains that with the KVM code being merged in Qemu development and integration of new and bigger features will evolve faster.

And last but not least Xen has released 2 minor maintenance releases for their 3.1 and 3.2 branches Xen 3.3.1 and Xen 3.2.3 are now available for download.
