Great! Do you all need an email notification when the -rc releases come out for the stable trees, or can you trigger off of the -rc stable git tree? Different CI systems work in different ways :) And if you can reply to the -rc release emails with a "Tested-by:" tag, I will be glad to add that to the release commit when that happens to show that you all have tested the release. > And we will start from ARM64 and X86 architecture first, and then extend > to other platforms.

That's fine, it is not something that happens at a regular interval. > Does this sound good to you? Yes it does, thank you so much. greg k-h
