The release adopts Symfony's TypeInfo component for more precise type definitions, adds forced typing via the #[MapTo] attribute, implements nesting for deeply nested object transformations, and supports Symfony's ObjectMapperInterface with optimized code generation. The update also improves polymorphism handling through class-level discriminator logic and includes an enhanced Symfony Profiler panel for debugging mappings. Requires PHP 8.4 or higher. ## Full article daily.dev links to this article rather than hosting it.
