Version 4.28 fixes several critical bugs across EC handling, S3 audit logging, and volume server stability.

Why it matters: These bugfixes eliminate crashes (e.g., shell volumeServer.evacuate panic), correct EC disk‑counting errors, surface previously hidden stat errors during idx scrub, and improve S3 request auditing—directly enhancing reliability for developers, SREs, and security engineers.

Summary

AI summary
