I'm announcing the release of the 2.6.36.4 kernel.
All users of the 2.6.36 kernel series must upgrade.
No, scratch that, you should move to the .37 kernel series as this is
the last .36 kernel to be released. It's now "end of life", "dead",
"buried", "pining for the fjords", or whatever term you and your
company uses for things that are no more.
The updated 2.6.36.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.36.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.36.y.git;a=summary
thanks,
greg k-h
