I'm announcing the release of the 2.6.39.4 kernel.
All users of the 2.6.39 kernel series must upgrade.
Please note, this is the LAST release of the 2.6.39 kernel series. All
users of 2.6.39 should be moving to 3.0 right now. This tree is now
end-of-life, please plan accordingly.
The updated 2.6.39.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.39.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.39.y.git;a=summary
thanks,
greg k-h
