I'm announcing the release of the 4.20.8 kernel.
All users of the 4.20 kernel series must upgrade.
The updated 4.20.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.20.y
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary
thanks,
greg k-h

The tarballs would not have been created if the git note was not there.
So are you sure it isn't present?
Hm, odd, it doesn't look like it is, wow, I really messed this one up...
Ok, both notes now regenerated. That's what I get for trying to do 4
releases at the same time :(

I'm announcing the release of the 4.20.8 kernel.
All users of the 4.20 kernel series must upgrade.
The updated 4.20.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.20.y
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary
thanks,
greg k-h
