HashiCorp has released Terraform 0.12, which it describes as a “major update” across the “breadth and depth” of the Infrastructure as Code tool. The new version features first-class expression syntax, which “allows expressions to be used directly in any situation where a value is expected”. Previously, non-literal expressions had to be included as interpolation sequences inside strings. v0.12 has a  generalized type system which “makes composition more convenient by giving more options for passing objects and other values between modules.” It also includes a new plan renderer, which integrates with the new type system, and shows changes “in a form that resembles the configuration language, and which indicates nested structures by indentation.”

No more casual release Fridays with Serverless Framework Enterprise

Admins can, for example, enable the framework to issue temporary AWS access keys to allow deployment. It cites the example of ensuring teams are not permitted to deploy to production on a Friday.
