3.1057.029 May 2026
Release notes
3.1057.0(2026-05-29)

Bug Fixes
- client-rds-data:
  - ArrayValue member element types are now nullable: booleanValues is (boolean | null)[], longValues and doubleValues are (number | null)[], stringValues is (string | null)[], and arrayValues is (ArrayValue | null)[]. This reflects that SQL array responses can contain NULL elements. Existing TypeScript code that reads elements as non-nullable values won't compile; migrate by changing the target type to nullable, using the nullish coalescing operator ?? to supply a default, or using .filter(v => v !== null). (43e8abc9)

Release notes
3.1000.0(2026-02-27)

New Features
- client-arc-region-switch: Post-Recovery Workflows enable customers to maintain comprehensive disaster recovery automation. This allows customer SREs and leadership to have complete recovery orchestration from failover through post-recovery preparation, ensuring Regions remain ready for subsequent recovery events. (3abb5202)
- client-keyspacesstreams: Added support for Change Data Capture (CDC) streams with Duration DataType. (59b94328)
- client-batch: This feature allows customers to specify the minimum time (in minutes) that AWS Batch keeps instances running in a compute environment after all jobs on the instance complete (25f4947a)
- client-cognito-identity-provider: Cognito is introducing a two-secret rotation model for app clients, enabling seamless credential rotation without downtime. Dedicated APIs support passing in a custom secret. Custom secrets need to be at least 24 characters. This eliminates reconfiguration needs and reduces security risks. (582a3813)
- client-bedrock: Added four new model lifecycle date fields, startOfLifeTime, endOfLifeTime, legacyTime, and publicExtendedAccessTime. Adds support for using the Converse API with Bedrock Batch inference jobs. (29b1fe6d)
- client-odb: ODB Networking Route Management is a feature improvement which allows for implicit creation and deletion of EC2 Routes in the Peer Network Route Table designated by the customer via new optional input. This feature release is combined with Multiple App-VPC functionality for ODB Network Peering(s). (d372d85d)
- client-customer-profiles: This release introduces an optional SourcePriority parameter to the ProfileObjectType APIs, allowing you to control the precedence of object types when ingesting data from multiple sources. Additionally, WebAnalytics and Device have been added as new StandardIdentifier values. (6166dfb7)
- client-connect: Deprecate EvaluationReviewMetadata's CreatedBy and CreatedTime, add EvaluationReviewMetadata's RequestedBy and RequestedTime (df058ded)
- client-ram: Resource owners can now specify ResourceShareConfiguration request parameter for CreateResourceShare API including RetainSharingOnAccountLeaveOrganization boolean parameter (3cc0ca9d)
- client-health: Updates the regex for validating availabilityZone strings used in the describe events filters. (eded08f6)
- client-transcribe-streaming: AWS Transcribe Streaming now supports specifying a resumption window for the stream through the SessionResumeWindow parameter, allowing customers to reconnect to their streams for a longer duration beyond stream start time. (56168c57)
Tests
- clients: enable snapshots for small subset of clients (#7790) (822c995d)
