⚠ BREAKING CHANGES

• lambda: Runtime.NODEJS_LATEST now resolves to nodejs24.x in every region. Customers who pin to a concrete runtime (Runtime.NODEJS_22_X, useLatestRuntimeVersion: false in aws-lambda-nodejs.NodejsFunction) are unaffected. Existing AWS::Lambda::Function resources synthesized with NODEJS_LATEST will see Runtime: nodejs22.x → Runtime: nodejs24.x on next deploy. Lambda accepts runtime updates in place.

  Customer-code compatibility — IMPORTANT: Node.js 24 removes support for callback-style asynchronous handlers ((event, context, callback) => {...}) per the launch blog. Customers whose Lambda code still uses callback-based handlers will see runtime errors after the bump. Customers should migrate to async (event, context) => {...} or pin to Runtime.NODEJS_22_X explicitly.

Superseded by #359, which bumps aws-cdk-lib to 2.260.0 in aws/cdk (manifest + lockfile) alongside the aws-cdk CLI floor bump needed for cloud-assembly schema v54 and the @aws-sdk / cli-installer fixes. #359 verifies synth against main with no resource diffs. Closing this in favor of the consolidated PR.
