It seems that the details of the pull request you’re referring to are missing or have not been provided. To create a summary for an undefined pull request for the Thanos project, I would typically need information such as:

  1. Title of the Pull Request: What specific feature or fix does this PR address?
  2. Description: A brief overview of what the developer is trying to achieve with this PR.
  3. Changes Made: Key changes or file modifications included in the pull request.
  4. Reasons for Changes: Why were these changes necessary? This might include bug fixes, performance improvements, new features, etc.
  5. Impact: How do the changes affect the project? Are there any breaking changes, new dependencies, or required updates for users?
  6. Tests or Validation: Any new tests added or existing tests modified? What testing framework was used?

If you can provide this information, I’ll be able to create a comprehensive summary for you. Alternatively, if you’re looking for a general template for a PR summary, I can provide that as well. Let me know!
