Some exciting new features include:

1) A new and improved interactive interpreter, based on PyPy’s, featuring multi-line editing and color support

2) An experimental free-threaded build mode, which disables the Global Interpreter Lock, allowing threads to run more concurrently.

3) A preliminary, experimental JIT, providing the ground work for significant performance improvements.
