BREAKING CHANGES
=========
* DynamoDB AutoScaling: Instead of `addReadAutoScaling()`, call `autoScaleReadCapacity()`, and similar for write scaling.
* CloudFormation resource usage: If you use L1s, you may need to change some `XxxName` properties back into `Name`. These will match the CloudFormation property names.
* You must use the matching `aws-cdk` toolkit when upgrading to this version, or context providers will cease to work. All existing cached context values in `cdk.json` will be invalidated and refreshed.
