AWS CDK June 2026: Node.js 24 breaks callback handlers, new explore & validate commands
AWS CDK v2.258-260 and CLI v2.1126-1128 ship with Node.js 24 as the latest runtime, breaking callback-style Lambda handlers. New commands cdk explore and cdk validate provide visual assembly browsing and standalone validation. Token resolution is ~25% faster.

The Node.js 24 breaking change is a necessary migration, but the new explore and validate commands meaningfully improve developer experience.
