+### Added
+
+**Pydantic v2 Support**

+- Convert OpenAPI 3 schemas to Python models: `create_models_from_openapi3(schema)`
+- Supports JSON and YAML input (with pyyaml)
+
+**Plugin System for Custom Generators**
+- `register_generator()` - register custom generator
+- `unregister_generator()` - remove custom generator
+- `list_generators()` - list all available generators
+- Base classes: `BaseGenerator`, `ORMGenerator`, `DataModelGenerator`
