It seems there is no specific information or details provided about the Pull Request from the Thanos project. To create a summary for an advanced developer, I would need the following details:

  1. Title of the Pull Request: What is the main focus or feature being addressed?
  2. Description: A brief overview of what changes are being made and why.
  3. Scope: What parts of the codebase does the Pull Request affect?
  4. Key Changes: What significant changes have been implemented (new features, bug fixes, refactoring)?
  5. Related Issues: Are there any associated issues or discussions that provide context for this PR?
  6. Testing: What kind of testing has been done or needs to be done?
  7. Impact: What is the expected impact of these changes on the existing code or functionality?
  8. Review notes: Any specific areas where the author seeks feedback from reviewers?

If you provide any of this information, I can help create a more tailored summary.
