AWS cli documentation change

Service: cli · 2026-04-25 · Documentation low

File: cli/latest/reference/s3api/write-get-object-response.md

Summary

Added new checksum parameters (SHA512, MD5, XXHASH64, XXHASH3, XXHASH128) for data integrity verification and updated CLI version reference

Security assessment

The change adds documentation for new checksum parameters that enable data integrity verification, which is a security feature for ensuring data hasn't been corrupted or tampered with during transmission. However, there's no evidence this addresses a specific security vulnerability or incident.
