 OSlash (Ø) is a library for learning and understanding functional programming in Python 3.12+. It re-implements
 concepts from [Learn You a Haskell for Great Good!](http://learnyouahaskell.com/) using Python with modern type annotations. OSlash unifies
 functional and object-oriented paradigms by grouping related functions within classes. Objects are never used
 for storing values or mutable data; data exists only within function closures.
 
+## ✨ What's New in 1.0
+
+**OSlash 1.0 is a complete modernization** for Python 3.12+:
+
+- **Modern Type System**: Fully type-checked with Pyright in strict mode
+- **PEP 695 Syntax**: Clean type parameters (`class Maybe[T]:` instead of `Generic[T]`)
+- **Modern Tooling**: Built with uv, formatted with ruff, validated with pre-commit hooks
+- **Production Status**: Stable release ready for educational use
+
 **Type Safety**: OSlash is fully type-checked with Pyright in strict mode, providing excellent IDE support and catching errors at development time. It leverages Python 3.12's PEP 695 type parameter syntax for clean, ergonomic generic types.
 
 OSlash is intended to be a tutorial. For practical functional programming in Python in production environments you
