[Libvirt-announce] Release of libvirt-2.2.0

[Daniel Veillard]

  Since the issue I had with rc2 was apparently just on my setup, I just pushed the release.
It is available as usual as signed tarball and rpms from :

   ftp://libvirt.org/libvirt/

I also pushed 2.2.0 for the python bindings which you can find at:

   ftp://libvirt.org/libvirt/python/

This is not a very big release, around 220 commits, august sounds like vacations, plus a number
of the developpers travelled to KVM forun so development took a bit of a hit. As a result we
