Amazon Verified Permissions now supports Cedar 4.5

Amazon Verified Permissions now supports Cedar 4.5. This enables customers to use the latest Cedar features, including the “is” operator, which allows customers to grant access based on resource types. For example, in a petstore application, you can use the “is” operator to write a policy that only grants administrators permission to view a resource if that resource "is" an invoice. This addition enhances Cedar's type system and helps catch potential type-related errors early in policy development. You can learn about other enhancements to Cedar on the Cedar releases page.

Amazon Verified Permissions is a permissions management and fine-grained authorization service for the applications that you build. Amazon Verified Permissions uses the Cedar policy language to enable developers and admins to define policy-based access controls using roles and attributes.

Amazon Verified Permissions supports Cedar 4.5 in all AWS Regions where the service is available. All new accounts and backward-compatible accounts have been automatically upgraded to Cedar-4, and no additional actions are required.
