[Libvirt-announce] Release of libvirt-2.3.0



  We are a little late but that allowed us to catch a regression before it impacted
the release :)
  I have tagged the release in git, pushed signed tarball and rpms to the usual place:

    ftp://libvirt.org/libvirt/

I also pushed the associated python bindings release available at:

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