From: Greg Kroah-Hartman
Date: Wed Aug 19 2020 - 04:51:10 EST

I'm announcing the release of the 4.19.140 kernel.

All users of the 4.19 kernel series must upgrade.

The updated 4.19.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.19.y
and can be browsed at the normal kernel.org git web browser:
https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary

thanks,

greg k-h
