Release of libvirt-1.2.4

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



  As planned I tagged the release in git and pushed the tarball and
signed rpms to the usual place:

  ftp://libvirt.org/libvirt/

I also generated those for python too even if the only change is a
spec file update, they are in the python subdir.

 This is a smaller than average release, with most of the changes
on code refactoring, portability and bug fixes, so no big features
here but general improvements:
