It seems that there is no specific information provided about the Pull Request you’re referring to for the Thanos project. To create a summary, I would need details such as the purpose of the Pull Request, key changes or features introduced, any relevant issues it addresses, and the overall impact or enhancements it brings to the project.

If you provide this information or a description of the code changes and their purpose, I can help you craft a detailed summary targeted at an advanced developer.
