2.49.3 2026-07-24

AWS Artifact

• Features

  • Added the PutComplianceInquiryFeedback API, enabling customers to submit feedback on compliance inquiry responses. Customers can rate responses as helpful or not helpful and provide optional reason codes and comments.

AWS SDK for Java v2

• Features

  • Updated endpoint and partition metadata.

• Bugfixes

  • Fixed several delegating AsyncRequestBody implementations (including those used by S3 Transfer Manager uploads) that reported the request-body type as unknown in the user-agent business metric instead of the actual type (file, bytes, or stream).
  • Update ResponseInputStream, to only return 0 from available() if the stream is closed; in other cases, if the wrapped stream returns 0 from available(), 1 is returned instead. This is to avoid cases where other classes such as java.util.zip.GZIPInputStream misinterpret this as meaning the stream is closed.
