v1.16.0

⚠ BREAKING CHANGES

• core: template file names in cdk.out for new projects created by cdk init will use stack.artifactId instead of the physical stack name to enable multiple stacks to use the same name. In most cases the artifact ID is the same as the stack name. To enable this fix for old projects, add the context key @aws-cdk/core:enableStackNameDuplicates: true in your cdk.json file.
