+
+### Added
+
+- 🧪 **Support for Mixed and Union Types (anyOf/nullables)**: mcpo now accurately exposes OpenAPI schemas with anyOf compositions and nullable fields.
+- 🧷 **Authentication-Required Docs Access with --strict-auth**: When enabled, the new --strict-auth option restricts access to both the tool endpoints and their interactive documentation pages—ensuring sensitive internal services aren’t inadvertently exposed to unauthenticated users or LLMs.
+- 🧬 **Custom Schema Definitions for Complex Models**: Developers can now register custom BaseModel schemas with arbitrary nesting and field variants, allowing precise OpenAPI representations of deeply structured payloads—ensuring crystal-clear docs and compatibility for multi-layered data workflows.
+- 🔄 **Smarter Schema Inference Across Data Types**: Schema generation has been enhanced to gracefully handle nested unions, nulls, and fallback types, dramatically improving accuracy in tools using variable output formats or flexible data contracts.
