@parthea I see that the new release version is uploaded to pypi https://pypi.org/project/google-cloud-spanner/.
But the build failed with error

HTTPError: 400 Bad Request from [https://upload.pypi.org/legacy/](https://www.google.com/url?q=https://upload.pypi.org/legacy/&sa=D)        
         The digest supplied does not match a digest calculated from the        
         uploaded file.

A rebuild gave an error that file already exists.

Any idea if there is any action item needed here?

[parthea]

No action is needed as this version exists on PyPI. I've also tested importing this version locally. I've closed #1147
