@jackfrancis may I know what the change in the pause image 1.4.1 is?

[jackfrancis]

@jchauncey @sozercan can you answer @AbelHu's question?

[jchauncey]

runs the linux image as nonroot and included pipeline change for publishing the image to the airgap

[AbelHu]

Thanks for the answer, @jchauncey . Is it possible to add release notes for the pause images so we do not need to bother you later?

[jchauncey]

This is the last build that my team is building from our internal repo. From now own it will follow the upstream pause image release so the release notes will be there.
