It seems there was an error in retrieving the details of the Pull Request (PR) for the Thanos project, as it’s currently marked as “undefined.” Without specific information about the changes proposed in the PR, the contributors involved, or the context of the enhancements or fixes, I cannot provide a summary.

To assist you further, please share the relevant details or the key points of the PR you would like summarized. This should include aspects such as the goals of the PR, significant code changes, the rationale behind them, and any associated issues or discussions. With that information, I can help create a comprehensive summary tailored for an advanced developer.
