Doc Text:
.A new serialization mechanism for upload completions is supported A race condition in completion of multipart upload operations could fail if a client retried its complete operation while the original completion was still in progress. As a consequence, a multipart upload failed, especially, when it was slow to complete. This update introduces a new serialization mechanism for upload completions, and the multipart upload failures no longer occur.
