Apr 1, 2026

In April 2026, AWS CDK CLI delivered migration tooling improvements and a new orphan workflow that together reduce downtime and manual steps for CloudFormation migrations. The team hardened the import flow to handle non-addition changes gracefully, introduced zero-downtime resource detachment, and expanded test coverage to validate migration scenarios.

Feb 1, 2026

February 2026 monthly summary: Delivered cross-account DynamoDB global table replication support via a new TableV2MultiAccountReplica construct with automatic permission management and settings replication controls, enabling secure multi-account deployments. Implemented automatic resource policies and KMS permissions, added TableGrants with multiAccountReplicationTo/multiAccountReplicationFrom, and established validation rules (region checks, explicit table names, and encryption considerations). Fixed SID formatting in DynamoDB grants to ASCII-alphanumeric to resolve cross-account replication errors. Achieved comprehensive test coverage (unit and integration) and manual validation of bidirectional replication, demonstrating end-to-end reliability.

Jan 1, 2025

January 2025 monthly summary for aws/aws-cdk focusing on DynamoDB data protection improvements and governance alignment. Delivered a new DynamoDB Point-in-Time Recovery Specification (pointInTimeRecoverySpecification) with recoveryPeriodInDays to provide granular control over recovery, and deprecated the older pointInTimeRecovery property to promote the more comprehensive specification. This change strengthens data resiliency and supports granular DR planning for DynamoDB deployments within CDK.

December 2024

Dec 1, 2024

December 2024 monthly summary for aws/aws-cdk: Delivered two DynamoDB integration enhancements that improve scalability, configurability, and data precision. Implemented warm-throughput configuration for Table and TableV2 constructs and introduced kinesisPrecisionTimestamp for DynamoDB-integrated Kinesis streams, with CloudFormation support. These changes enable pre-configured read/write capacity, reduce the risk of over- or under-provisioning, and improve timestamp accuracy for analytics and event processing.

October 2024
