It looks like you’ve referred to an “undefined” Pull Request, meaning there are no specific details or context provided regarding the changes or the purpose of the Pull Request in the Thanos project.

To create a summary, I would need some information such as:

• The title of the Pull Request
• A brief description of the changes it introduces
• Which files are being modified
• The rationale behind the changes
• Any relevant issues it addresses
• Any discussions or reviews from other contributors

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