@olavloite Interesting. Why #4336 does not appear in this release? I'd like to release the tagging work together.

Hmm... That's strange. The commit is in the release, but it does not show up in the list of changes. I think that is because the commit got a non-conforming commit message: https://github.com/googleapis/google-cloud-go/pull/4336/commits (It starts with Revert ("revert...)

I guess the best solution in this case is to manually edit the release notes.

@codyoss I can't push my change to this PR. Is there any way that I can update the release note (CHANGES.md) by adding the missing commit?

[hengfengli]

It's interesting that I did it successfully via Github UI by directly editing the file. But when I did update the file locally, I failed to push my change. What I have done is:

gh pr checkout 4339
vim spanner/CHANGES.md
git add spanner/CHANGES.md
git commit
git push origin HEAD:refs/pull/4339/head

I got the error:

Looks like it is all good now, lmk if my assistance is still needed.
