The latest release of HashiCorp Sentinel includes several new features that improve the developer experience, including improved configuration syntax, support for static JSON data, named functions, simplified expressions for unknown values, and per-policy parameter values. These features enhance policy authoring and evaluation, making it easier to create reusable policies with dynamic logic and manage exemptions. The updated language supports a standardized naming convention, allows overriding default configurations, and provides two new helpers to determine if a value is defined or not. The features are designed to make Sentinel more accessible to developers and improve the overall policy authoring experience.
