AWS AmazonS3 documentation change

Service: AmazonS3 · 2026-04-25 · Documentation low

File: AmazonS3/latest/userguide/metadata-tables-inventory-schema.md

Summary

Updated the checksum_algorithm field in inventory schema documentation to include newly supported algorithms (MD5, XXHash64, XXHash3, XXHash128, SHA-512).

Security assessment

This change updates the inventory schema documentation to include new checksum algorithms. While checksum information in inventory can support integrity verification processes, there's no evidence this addresses a specific security vulnerability. The change adds documentation about security-related metadata fields but doesn't indicate a security issue was fixed.
