eks: (experimental module) the Mapping struct was renamed to AwsAuthMapping.
core: Arn.parseArn now returns empty string for nullable Arn components. Users who were depending on an undefined value will now receive the falsy empty string.
ecr-assets: all docker image assets are now pushed to a single ECR repository named aws-cdk/assets with an image tag based on the hash of the docker build source directory (the directory where your Dockerfile resides). See PR #5733 for details and discussion.
autoscaling: AutoScaling by using scaleOnMetric will no longer force the alarm period to 1 minute, but use the period from the Metric object instead (5 minutes by default). Use metric.with({ period: Duration.minute(1) }) to create a high-frequency scaling policy.
