I'm announcing the release of the 6.6.156 kernel.
All users of the 6.6 kernel series must upgrade.
The updated 6.6.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-6.6.y
and can be browsed at the normal kernel.org git web browser:

thanks,
greg k-h
