AWS CloudFormation announces new language extensions transform

AWS CloudFormation announces the general availability of a new transform supporting extensions to the CloudFormation template language. AWS CloudFormation is an Infrastructure as Code (IaC) service that lets you model, provision, and manage AWS and third-party resources by authoring templates which are formatted text files in JSON or YAML. This release introduces a language transform called ‘AWS::LanguageExtensions.’ When declared in a template, the transform enables extensions to the template language. At launch, these include: new intrinsic functions for length (Fn::Length) and JSON string conversion (Fn::ToJsonString), and support for intrinsic functions and pseudo-parameter references in update and deletion policies.
