- Refactored to keep every transformation of built-in types (e.g. FS, Secret, etc) to/from CUE in the same place (plancontext) - dagger.#Service and dagger.#Secret are now following the new FS-like format (e.g. `_service: id: string`) - Backward compatibility - dagger.#Stream is now an alias for dagger.#Service Signed-off-by: Andrea Luzzardi <aluzzardi@gmail.com>
