AWS cli documentation change

Service: cli · 2025-06-28 · Documentation low

File: cli/latest/reference/s3api/upload-part-copy.md

Summary

Updated CLI version reference and added documentation about 'aws:fsx' encryption requirement for Amazon FSx file systems via S3 access points

Security assessment

Explicitly documents encryption requirements for FSx integration, which qualifies as security feature documentation. However, there's no evidence this change addresses an existing security vulnerability - it appears to be proactive guidance rather than a response to a security issue.
