 ### Added
 
+- Add `UNKNOWN_TO_SDK` value to enums that is used when the API returns an value that is not (or not yet) knwon by the AsyncAws
 - AWS api-change: Introduces Spark workgroup features including log persistence, S3/CloudWatch delivery, UI and History Server APIs, and SparkConnect 3.5.6 support. Adds DPU usage limits at workgroup and query levels as well as DPU usage tracking for Capacity Reservation queries to optimize performance and costs.
 
 ### Dependency bumped

 ### Added
 
+- Add `UNKNOWN_TO_SDK` value to enums that is used when the API returns an value that is not (or not yet) knwon by the AsyncAws
 - AWS api-change: Added `us-isob-west-1` region
 - AWS api-change: Adds support for record sizes up to 10MiB and introduces new UpdateMaxRecordSize API to modify stream record size limits. Adds record size parameters to existing CreateStream and DescribeStreamSummary APIs for request and response payloads respectively.
 - AWS api-change: Adds support to configure warm throughput for on-demand streams in new UpdateStreamWarmThroughput API and existing CreateStream API and UpdateStreamMode API.

 ### Added
 
+- Add `UNKNOWN_TO_SDK` value to enums that is used when the API returns an value that is not (or not yet) knwon by the AsyncAws
 - AWS api-change: Added `us-isob-west-1` region
 - AWS api-change: Added support for new ECC_NIST_EDWARDS25519 AWS KMS key spec

 ### Added
 
+- Add `UNKNOWN_TO_SDK` value to enums that is used when the API returns an value that is not (or not yet) knwon by the AsyncAws
 - AWS api-change: Added `us-isob-west-1` region
 - Added `S3Client::putPublicAccessBlock()` method
 - AWS api-change: Amazon Simple Storage Service / Features: Add conditional writes in CopyObject on destination key to prevent unintended object modifications.
