Changes since 4.4.2: - v5.x rewrites the implementation using the standard library inspect module, dropping the code generation approach - Signature preservation is now based on functools.wraps internals - New contextmanager and asynccontextmanager decorator support - Python 3.8+ required; Python 2 no longer supported Also add test.sh to verify signature preservation and basic usage.
