It seems that the Pull Request (PR) you’re referring to is undefined, meaning there isn’t specific information available for it. To create an effective summary for such a PR in the Thanos project, I would need details such as the changes introduced, the files modified, the functionality affected, any issues it addresses, and relevant discussions or comments from reviewers.

If you provide additional context or key elements of the PR (like the title, main changes, purpose, etc.), I would be happy to help you craft a detailed summary for an advanced developer!
