__NOTICE__: This release includes a framework-wide [__breaking
change__](#712) which changes the type
of all the string resource attributes across the framework. Instead of using
strong-types that extend `cdk.Token` (such as `QueueArn`, `TopicName`, etc), we
now represent all these attributes as normal `string`s, and codify the tokens
into the string (using the feature introduced in [#168](#168)).
Furthermore, the `cdk.Arn` type has been removed. In order to format/parse ARNs,
use the static methods on `cdk.ArnUtils`.
See motivation and discussion in [#695](#695).
