It seems that the pull request you’re referring to is labeled as “undefined,” meaning there isn’t specific information available regarding its contents or context. Without details about the changes proposed in the pull request, such as the code modifications, the purpose of these changes, associated issues, or any relevant discussions, it isn’t possible to provide a summary focused on the project “thanos-io/thanos.”
