It appears that the Pull Request you intended to provide details for is currently undefined or missing. To create a summary, I would need specific information about the changes proposed in the Pull Request, such as:
- The primary purpose or goal of the PR.
- Key changes or additions made in the code.
- Any bug fixes or improvements.
- Impact on existing features or stability.

If you could provide this information or a specific context, I would be happy to help create a summary tailored for an advanced developer working on the thanos-io/thanos project.
