Python 3.14: Deferred Annotation Evaluation and a New Interpreter
2025-02-10

Python 3.14 is here with exciting updates! PEP 649 and PEP 749 introduce deferred annotation evaluation, boosting performance and simplifying annotation writing. A new tail-call-based interpreter offers significant speed improvements (9-15% geometric mean on pyperformance) on specific compilers and architectures. Finally, PEP 741 refines the Python configuration C API, paving the way for future enhancements. These updates combine to make Python faster and more powerful!
