It appears that there is no specific information provided about the Pull Request (PR) for the Thanos project. To create a summary for an advanced developer, I would typically need details such as:

• The purpose of the PR (new feature, bug fix, performance improvement, etc.)
• The files or modules affected
• Key changes or implementations introduced
• Any relevant context regarding why these changes are necessary
• Impact on existing functionality or backward compatibility
• Any tests added or modified
• Related issues or discussions linked to the PR

If you could provide more specifics about the Pull Request, I’d be happy to help you draft a detailed summary!
