AWS cli documentation change

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

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

Summary

Updated CLI version reference from 2.34.34 to 2.34.37 and added documentation for new checksum response fields (ChecksumSHA512, ChecksumMD5, ChecksumXXHASH64, ChecksumXXHASH3, ChecksumXXHASH128) in the get-object command output.

Security assessment

The change documents additional checksum fields that can be returned by the get-object operation, which helps with data integrity verification. This adds documentation about security features (checksums for integrity validation) but does not indicate a specific security issue being fixed. The change appears to be consistent with expanding checksum algorithm support across S3 operations.
