Sangjin Lee commented on YARN-5045:
-----------------------------------
Yes, I believe CHANGES.txt has been removed altogether, so we cannot update it
even if we wanted to.
I'm little unsure what it means for branch commits. I'm not sure if there was a
discussion on the implication for the branch commits. When we do the actual
merge to trunk, I don't think that the commit message of that commit will carry
any info on the branch commits. Are you aware of any discussion? Is the idea
that the branch will be preserved so that people can see the commit activities
there? [~vinodkv]?
