Hi, 1.3.0 was released 5 months ago. I hope you can get this for f20+. However I suggest that you should use a snapshot from git as the license may have been changed/modified. Thanks.
I had not updated the package hoping of see included in Fedora the native support in the kernel. Now the discussion has been started again in the lists.
