It seems that the pull request you mentioned is undefined or lacks specific details. To provide a targeted summary, I need more information about the contents, objectives, and changes proposed in the pull request related to the Thanos project.

If you could provide key elements such as the title, description, any associated issues, and the changes being made (e.g., new features, bug fixes, refactoring), I could help you create a comprehensive summary tailored for an advanced developer.
