[Libvirt-announce] Release of libvirt-2.4.0

[Daniel Veillard]

  It's out ! Not hearing any negative feedback on the release candidates
I went ahead, this is tagged in git and signed tarball and rpms are now
at the usual place:

   ftp://libvirt.org/libvirt/


I also made a libvirt-python release though it is virtually identical to
2.3.0, to be found at:
