v2.2.0

New Features

• Nested Items — Validate arrays of nested objects via #[Field(items: OrderItemRequest::class)]. Each element goes through the full pipeline (validation, casting, pre/post-processing). Validation errors use dot-notation (items.0.product).
• handleArray() — Process raw data arrays without a PSR-7 request.

Configuration Validation

• items must reference a class extending Request
• items requires array or ?array property type
• items and generator are mutually exclusive
