Subject: Linux 2.6.32.39

I'm announcing the release of the 2.6.32.39 kernel.

All users of the 2.6.32 series must upgrade.

The updated 2.6.32.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/longterm/linux-2.6.32.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/longterm/linux-2.6.32.y.git;a=summary

thanks,

greg k-h
