AWS cli: Bedrock Agent untag-resource: ARN pattern adds retrieval-instruction resources

Service: cli · 2026-10-20 · Documentation low

File: cli/latest/reference/bedrock-agent/untag-resource.md · Type: iam

Summary

Updates the AWS CLI reference version to 2.38.2 and extends the accepted resource ARN regex for UntagResource to include retrieval-instruction resources and alternate partitions (aws-cn, aws-us-gov, aws-eusc, aws-iso*).

Security assessment

Same ARN-pattern expansion as the tag-resource page, applied to UntagResource. It broadens the set of valid resource ARNs for tag removal (IAM resource-scoping relevance) but is a routine API surface update with no vulnerability or security guidance.

Evidence
