It seems like there was an error or omission in your request, as no specific details were provided regarding the Pull Request in the thanos-io/thanos project. To help you create a summary, I would need some information about the contents of the Pull Request, such as:

• The purpose of the PR (e.g., bug fix, feature enhancement, refactor, etc.)
• Key changes introduced (e.g., new files, modified files, specific functions or classes affected)
• Any relevant context or discussion points that have arisen during the PR review process
• Dependencies or related issues (e.g., issue numbers referenced)
• Testing or validation performed

If you can provide that information, I can help you craft a detailed and concise summary suitable for an advanced developer.
