It seems that there is no specific detail or content provided about the Pull Request (PR) you’re referring to for the Thanos project. To create an effective summary, I would need some context about the changes introduced in the PR, such as:

• The main objectives or goals of the PR.
• A description of the changes made (e.g., new features, bug fixes, optimizations).
• Any relevant files or areas of the codebase impacted by the changes.
• Dependencies, if any, that might be affected.
• Testing and validation performed to ensure the changes work as intended.
• Relevant discussions or issues that the PR addresses.

If you can provide any of these details, I would be happy to help you craft a summary that reflects its content and significance for an advanced developer.
