Warning : this new version of lightning will only work with thunderbird 3.0b2, so it will be deactivated if you switch back to thunderbird 2.0.

As always :

yum --enablerepo=remi install thunderbird-lightning

I have no more reason to keep thunderbird version 2, so, for the next update, thunderbird3 will be rename to thunderbird and will overide the standard version for Fedora  <= 10.

However, as this is not a final version, it is only available in English.
